www.austriamicrosystems.com/led-driver-ics/AS1119 revision 1.04 1 - 30 datasheet AS1119 144-led cross-plexing driver with 320ma charge-pump 1 general description the AS1119 is a compact led driver for 144 (90) single leds. the devices can be programmed via an i2c compatible interface. the AS1119 offers two blocks driving each 72 leds (3 blocks each 30leds) with 1/9 (1/6) cycle rate. the required lines to drive all 144 (90 )leds are reduced to 18 by using the cross-plexing feature opti- mizing space on the pcb. every block driving 72(30) leds can be analog dimmed from 1 to 30ma in 256 steps (8 bit). additionally each of the 144 (90) leds can be dimmed individually with 8-bit allowing 256 steps of linear dimming. to reduce cpu usage up to 6 frames can be stored with individual time delays between frames to play small animations automatically. the AS1119 operates from 2.7v to 5.5v and includes a 320ma charge-pump to drive also white leds. the charge-pump operates in 2:3 and 1:2 mode. the AS1119 features very low shutdown and operational current. the device is available in a ultrasmall 36-pin wl-csp. figure 1.

www.austriamicrosystems.com/led-driver-ics/AS1119 revision 1.04 10 - 30 AS1119 datasheet - detailed description i2c interface the AS1119 supports the i2c serial bus and data transmission protocol in fast mode at 1mhz. the AS1119 operates as a slave on t he i2c bus. the bus must be controlled by a master device that generates the serial clock (scl), controls the bus access, and generates the start and stop conditions. connections to the bus are made via the open-drain i/o pins scl and sda. figure 14. i2c interface initialisation figure 15. bus protocol the bus protocol (as shown in figure 15 ) is defined as: - 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 control signals. the bus conditions are defined as: - bus not busy . data and clock lines remain high. - start data transfer . a change in the state of the data line, from high to low, while the clock is high, defines a start condition. - stop data transfe r. a change in the state of the data line, fr om low to high, while the clock line is high, defines the stop condition. - data valid . the state of the data line represents valid data, wh en, after a start condition, the data line is stable for the duration of the high period of the clock signal. there is one clock pulse per bit of data. each data transfer is initiated with a start condition and terminated with a stop cond ition. the number of data bytes transferred between start and stop conditions is not limited and is determined by the master device. the information is transferred byte-wise and each receiver acknowledges with a ninth-bit. within the i2c bus specifications a high-speed mode (3.4mhz clock rate) is defined. - acknowledge : each receiving device, when addressed, is obliged to generate an acknowledge after the recep- tion of each byte. the master device mu st generate an extra clock pulse that is associated with this acknowledge bit. a device that acknowledges must 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 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 19 81 9 8 1 0 0 11 a1 a0 r/w d15 d14 d13 d12 d11 d10 d9 d8 a0 and a1 are defined by the pins ad0 and ad1. pin ad0 and ad1 must not be left floating. scl sda sdi scl slave address r/w direction bit start 1 2 6 7 8 9 1 23-8 8 9 ack msb repeat if more bytes transferred stop or repeated start ack from receiver ack from receiver ack ams ag technical content still valid
www.austriamicrosystems.com/led-driver-ics/AS1119 revision 1.04 11 - 30 AS1119 datasheet - detailed description acknowledge bit on the last byte that has been clocked out of the slave. in this ca se, the slave must leave the data line high to enable the master to generate the stop condition. - figure 15 on page 10 details how data transfer is accomplished on the i2c bus. depending upon the state of the r/w bit, two types of data transfer are possible: - master transmitter to slave receiver . the first byte transmitted by the master is the slave address, followed by a number of data bytes. the slave returns an acknowled ge bit after the slave address and each received byte. - slave transmitter to master receiver . the first byte, the slave address, is transmitted by the master. the slave then returns an acknowledge bit. next, a number of data bytes are transmitted by the slave to the master. the master returns an acknowledge bit after all received bytes other than the last by te. at the end of the last received byte, a not-acknowledge is returned. the master device generates all of the serial clock pulses and the start and stop conditions. a transfer is ended with a stop condition or a repeated start condition. since a repeated start condition is also the beginning of the next serial transfer, the bus will not be released. the AS1119 can operate in the following slave modes: - slave receiver mode . serial data and clock are received through sda and scl. after each byte is received, an acknowledge bit is transmitted. start and stop conditio ns are recognized as the beginning and end of a serial transfer. address recognition is performed by hardware after reception of the slave address and direction bit. - slave transmitter mode . the first byte (the slave address) is received and handled as in the slave receiver mode. however, in this mode the direction bit will indicate that the transfer direction is reversed. serial data is transmitted on sda by the AS1119 while the serial clock is input on scl. start and stop conditions are recog- nized as the beginning and end of a serial transfer. i2c device address byte the address byte (see figure 16) is the first byte received following the start condition from the master device. figure 16. i2c device address byte - the bit 1 and bit 2 of the address byte are the device select pins ad0 and ad1, which must be set to v dd or to gnd. a maximum of four devices with the same pre-set code can therefore be connec ted on the same bus at one time. - the last bit of the address byte (r/w ) define the operation to be performed. when set to a 1 a read operation is selected; when set to a 0 a write operation is selected. following the start condition, the AS1119 monitors the i2c bus, checking the device type identifier being transmitted. upon rec eiving the address code, and the r/w bit, the slave device outputs an acknowledge signal on the sda line. command byte the AS1119 operation, ( see table 15 on page 21 ) is determined by a command byte (see table 17) . figure 17. command byte 0 1 1 1 0 ad1 ad0 r/w msb654321lsb address: a7 a6 a5 a4 a3 a2 a1 a0 msb654321lsb ams ag technical content still valid
