As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region (minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions. The combined TSP and VHYS specifications are due to Schmitt Trigger inputs which provide improved noise spike suppression. This eliminates the need for a TI specification for standard operation.

The 24C02C supports a bidirectional 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as transmitter, and a device receiving data as receiver. The bus has to be controlled by a master device which generates the serial clock (SCL), controls the bus access, and generates the Start and Stop conditions, while the 24C02C works as slave. Both master and slave can operate as transmitter or receiver but the master device determines which mode is activated. TABLE 2-1: Name Vss SDA SCL VCC A0, A1, A2 WP PIN FUNCTION TABLE Function Ground Serial Data Serial Clock +4.5V to 5.5V Power Supply Chip Selects Hardware Write-Protect 2.1 SDA Serial Data This is a bidirectional pin used to transfer addresses and data into and data out of the device. It is an open drain terminal, therefore the SDA bus requires a pull-up resistor to VCC (typical 10 k for 100 kHz, 2 k for 400 kHz). For normal data transfer SDA is allowed to change only during SCL low. Changes during SCL high are reserved for indicating the Start and Stop conditions. 2.2 SCL Serial Clock This input is used to synchronize the data transfer from and to the device. 2.3 A0, A1, A2 The levels on these inputs are compared with the corresponding bits in the slave address. The chip is selected if the compare is true. Up to eight 24C02C devices may be connected to the same bus by using different Chip Select bit combinations. These inputs must be connected to either VCC or VSS. 2.4 WP This is the hardware write-protect pin. It must be tied to VCC or VSS. If tied to Vcc, the hardware write protection is enabled. If the WP pin is tied to Vss the hardware write protection is disabled. 2.5 Noise Protection The 24C02C employs a VCC threshold detector circuit which disables the internal erase/write logic if the VCC is below 3.8 volts at nominal conditions. The SCL and SDA inputs have Schmitt Trigger and filter circuits which suppress noise spikes to assure proper device operation even on a noisy bus. DS21202D-page 4 2003 Microchip Technology Inc. 24C02C 4.0 BUS CHARACTERISTICS The following bus protocol has been defined: * Data transfer may be initiated only when the bus is not busy. * During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line while the clock line is high will be interpreted as a Start or Stop condition. Accordingly, the following bus conditions have been defined (Figure 4-1). The data on the line must be changed during the low period of the clock signal. There is one bit of data per clock pulse. Each data transfer is initiated with a Start condition and terminated with a Stop condition. The number of the data bytes transferred between the Start and Stop conditions is determined by the master device and is theoretically unlimited, although only the last sixteen will be stored when doing a write operation. When an overwrite does occur it will replace data in a first in first out fashion. 4.1 Bus not Busy (A) 4.5 Acknowledge Both data and clock lines remain high. 4.2 Start Data Transfer (B) Each receiving device, when addressed, is required to generate an acknowledge after the reception of each byte. The master device must generate an extra clock pulse which is associated with this Acknowledge bit. Note: The 24C02C does not generate any Acknowledge bits if an internal programming cycle is in progress. A high-to-low transition of the SDA line while the clock (SCL) is high determines a Start condition. All commands must be preceded by a Start condition. 4.3 Stop Data Transfer (C) A low-to-high transition of the SDA line while the clock (SCL) is high determines a Stop condition. All operations must be ended with a Stop condition. 4.4 Data Valid (D) The state of the data line represents valid data when, after a Start condition, the data line is stable for the duration of the high period of the clock signal. The device that acknowledges has to pull down the SDA line during the Acknowledge clock pulse in such a way that the SDA line is stable low during the high period of the acknowledge related clock pulse. Of course, setup and hold times must be taken into account. A master must signal an end of data to the slave by not generating an Acknowledge bit on the last byte that has been clocked out of the slave. In this case, the slave must leave the data line high to enable the master to generate the Stop condition (Figure 4-2). FIGURE 4-1: SCL (A) (B) DATA TRANSFER SEQUENCE ON THE SERIAL BUS CHARACTERISTICS (C) (D) (C) (A) SDA Start Condition Address or Acknowledge Valid Data Allowed to Change Stop Condition FIGURE 4-2: ACKNOWLEDGE TIMING Acknowledge Bit SCL 1 2 3 4 5 6 7 8 9 1 2 3 SDA Data from transmitter Transmitter must release the SDA line at this point allowing the Receiver to pull the SDA line low to acknowledge the previous eight bits of data. Data from transmitter Receiver must release the SDA line at this point so the Transmitter can continue sending data. 2003 Microchip Technology Inc. DS21202D-page 5 24C02C 5.0 DEVICE ADDRESSING FIGURE 5-1: CONTROL BYTE FORMAT Read/Write Bit Chip Select Bits A control byte is the first byte received following the Start condition from the master device (Figure 5-1). The control byte consists of a four bit control code; for the 24C02C this is set as 1010 binary for read and write operations. The next three bits of the control byte are the Chip Select bits (A2, A1, A0). The Chip Select bits allow the use of up to eight 24C02C devices on the same bus and are used to select which device is accessed. The Chip Select bits in the control byte must correspond to the logic levels on the corresponding A2, A1, and A0 pins for the device to respond. These bits are in effect the three Most Significant bits of the word address. The last bit of the control byte defines the operation to be performed. When set to a one a read operation is selected, and when set to a zero a write operation is selected. Following the Start condition, the 24C02C monitors the SDA bus checking the control byte being transmitted. Upon receiving a 1010 code and appropriate Chip Select bits, the slave device outputs an Acknowledge signal on the SDA line. Depending on the state of the R/W bit, the 24C02C will select a read or write operation. Control Code S 1 0 1 0 A2 A1 A0 R/W ACK Slave Address Start Bit Acknowledge Bit 5.1 Contiguous Addressing Across Multiple Devices The Chip Select bits A2, A1, A0 can be used to expand the contiguous address space for up to 16K bits by adding up to eight 24C02C devices on the same bus. In this case, software can use A0 of the control byte as address bit A8, A1 as address bit A9, and A2 as address bit A10. It is not possible to write or read across device boundaries. DS21202D-page 6 2003 Microchip Technology Inc. 24C02C 6.0 6.1 WRITE OPERATIONS Byte Write Following the Start signal from the master, the device code(4 bits), the Chip Select bits (3 bits) and the R/W bit which is a logic low is placed onto the bus by the master transmitter. The device will acknowledge this control byte during the ninth clock pulse. The next byte transmitted by the master is the word address and will be written into the address pointer of the 24C02C. After receiving another Acknowledge signal from the 24C02C the master device will transmit the data word to be written into the addressed memory location. The 24C02C acknowledges again and the master generates a Stop condition. This initiates the internal write cycle, and during this time the 24C02C will not generate Acknowledge signals (Figure 6-1). If an attempt is made to write to the protected portion of the array when the hardware write protection has been enabled, the device will acknowledge the command but no data will be written. The write cycle time must be observed even if the write protection is enabled. operation, once the Stop condition is received an internal write cycle will begin (Figure 6-2). If an attempt is made to write to the protected portion of the array when the hardware write protection has been enabled, the device will acknowledge the command but no data will be written. The write cycle time must be observed even if the write protection is enabled. Note: Page write operations are limited to writing bytes within a single physical page, regardless of the number of bytes actually being written. Physical page boundaries start at addresses that are integer multiples of the page buffer size (or `page size') and end at addresses that are integer multiples of [page size - 1]. If a Page Write command attempts to write across a physical page boundary, the result is that the data wraps around to the beginning of the current page (overwriting data previously stored there), instead of being written to the next page as might be expected. It is therefore necessary for the application software to prevent page write operations that would attempt to cross a page boundary. 6.2 Page Write 6.3 The write control byte, word address and the first data byte are transmitted to the 24C02C in the same way as in a byte write. But instead of generating a Stop condition, the master transmits up to 15 additional data bytes to the 24C02C which are temporarily stored in the on-chip page buffer and will be written into the memory after the master has transmitted a Stop condition. After the receipt of each word, the four lower order address pointer bits are internally incremented by one. The higher order four bits of the word address remains constant. If the master should transmit more than 16 bytes prior to generating the Stop condition, the address counter will roll over and the previously received data will be overwritten. As with the byte write WRITE PROTECTION The WP pin must be tied to VCC or VSS. If tied to VCC, the upper half of the array (080-0FF) will be writeprotected. If the WP pin is tied to VSS, then write operations to all address locations are allowed.

DS21202D-page 7 24C02C 7.0 ACKNOWLEDGE POLLING 8.0 READ OPERATIONS Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). Once the Stop condition for a Write command has been issued from the master, the device initiates the internally timed write cycle. ACK polling can be initiated immediately. This involves the master sending a Start condition followed by the control byte for a Write command (R/W = 0). If the device is still busy with the write cycle, then no ACK will be returned. If no ACK is returned, then the Start bit and control byte must be re-sent. If the cycle is complete, then the device will return the ACK and the master can then proceed with the next Read or Write command. See Figure 7-1 for flow diagram. Read operations are initiated in the same way as write operations with the exception that the R/W bit of the slave address is set to one. There are three basic types of read operations: current address read, random read, and sequential read. 8.1 Current Address Read FIGURE 7-1: ACKNOWLEDGE POLLING FLOW Send Write Command The 24C02C contains an address counter that maintains the address of the last word accessed, internally incremented by one. Therefore, if the previous read access was to address n, the next current address read operation would access data from address n + 1. Upon receipt of the slave address with the R/W bit set to one, the 24C02C issues an acknowledge and transmits the eight bit data word. The master will not acknowledge the transfer but does generate a Stop condition and the 24C02C discontinues transmission (Figure 8-1). 8.2 Random Read Send Stop Condition to Initiate Write Cycle Send Start Send Control Byte with R/W = 0 Random read operations allow the master to access any memory location in a random manner. To perform this type of read operation, first the word address must be set. This is done by sending the word address to the 24C02C as part of a write operation. After the word address is sent, the master generates a Start condition following the acknowledge. This terminates the write operation, but not before the internal address pointer is set. Then the master issues the control byte again but with the R/W bit set to a one. The 24C02C will then issue an acknowledge and transmits the eight bit data word. The master will not acknowledge the transfer but does generate a Stop condition and the 24C02C discontinues transmission (Figure 8-2). After this command, the internal address counter will point to the address location following the one that was just read. Did Device Acknowledge (ACK = 0)? YES Next Operation NO 8.3 Sequential Read Sequential reads are initiated in the same way as a random read except that after the 24C02C transmits the first data byte, the master issues an acknowledge as opposed to a Stop condition in a random read. This directs the 24C02C to transmit the next sequentially addressed 8-bit word (Figure 8-3). To provide sequential reads the 24C02C contains an internal address pointer which is incremented by one at the completion of each operation. This address pointer allows the entire memory contents to be serially read during one operation. The internal address pointer will automatically roll over from address FF to address 00.
