Microcontroller Clock Generator with Watchdog
General Description
The MAX7389/MAX7390 replace ceramic resonators, crystals, and supervisory functions for microcontrollers in 3.3V and 5V applications. The MAX7389/MAX7390 provide a clock source, reset, and watchdog functions. The watchdog timer is pin programmable and provides watchdog timeout values in the 16ms to 2048ms range. The MAX7389 provides a separate watchdog output that is used as a status indicator or to control safety-critical system elements. The MAX7390 features a clock-speed select that reduces the output frequency by half. This functionality allows the microcontroller to operate at reduced power and may be used to extend the time available to perform housekeeping tasks, such as writing data to flash during a power failure. The MAX7389/MAX7390 clock outputs are factory programmed to a frequency in the 1MHz to 16MHz range. Four standard frequencies are available. Other frequencies are available upon request. The maximum operating supply current is 5.5mA with a clock frequency of 12MHz. Unlike typical crystal and ceramic resonator oscillator circuits, the MAX7389/MAX7390 are resistant to EMI and vibration, and operate reliably at high temperatures. The high-output drive current and absence of high-impedance nodes make the oscillator invulnerable to dirty or humid operating conditions. The MAX7389/MAX7390 are available in an 8-pin package. The MAX7389/MAX7390 standard operating temperature range is from -40C to +125C. MAX(R)

Detailed Description
The MAX7389/MAX7390 replace ceramic resonators, crystals, and supervisory functions for microcontrollers in 3.3V and 5V applications. The MAX7389/MAX7390 provide a clock source, reset, and watchdog functions. The watchdog timer is pin programmable and provides watchdog timeout values in the 16ms to 2048ms range. The MAX7389 provides a separate watchdog output that is used as a status indicator or to control safety-critical system elements. The MAX7390 features a clock-speed switch that reduces the output frequency by half. This functionality allows the microcontroller to operate at reduced power and may be used to extend the time available to perform housekeeping tasks, such as writing data to flash during a power failure. The integrated reset and watchdog functions provide the power-supply monitoring functions necessary to ensure correct microcontroller operation. The reset circuit has built-in power-supply transient immunity and provides both power-on reset and power-fail or brownout reset
functionality. Two standard factory-trimmed reset levels are available. The watchdog timer is programmable to eight individual timeout values and may be disabled for test purposes.
Clock Output (CLOCK)
The push-pull clock output (CLOCK) drives a groundconnected 1k load or a positive supply connected 500 load to within 300mV of either supply rail. CLOCK remains stable over the full operating voltage range and does not generate short output cycles during either power-on or power-off. A typical startup characteristic is shown in the Typical Operating Characteristics section. The MAX7390 clock output frequency is reduced by a factor of two by taking SPEED low. This functionality allows the microcontroller to operate at reduced power and may be used to extend the time available to perform housekeeping tasks.
Reset
The reset function drives the microcontroller reset input to prevent operation in the cases of the initial power-on setting, low power-supply voltages, and the failed

watchdog operations. Three reset output versions are available: push-pull RST, push-pull RST, and open-drain RST. The reset timeout period (tRST) is nominally 135s. Power-On Reset (POR) The internal power-on reset (POR) circuit detects the power-supply voltage (VCC) level at startup. The POR circuit starts the oscillator when VCC exceeds the reset rising threshold level (VTH+). The reset output remains asserted from the time VCC crosses the VTH+ and continues to be asserted for the reset timeout period (tRST). Upon completion of the reset timeout, the reset output is released. See Figure 1. Low-Voltage Lockout The reset output asserts whenever VCC drops below the reset falling threshold, VTH-. The difference between the reset rising and falling threshold values is VTH+ - (VTH-). The nominal hysteresis value is 2% of the reset rising threshold value. The reset detection circuitry provides filtering to prevent triggering on negative voltage spikes. See the Typical Operating Characteristics for a plot of maximum transient duration without causing a reset pulse vs. reset comparator overdrive. Figure 1 shows the reset output (RST/RST) behavior during power-up and brownout.
MAX7389/MAX7390
Watchdog
The watchdog function provides microprocessor monitoring by requiring the microprocessor to toggle an output pin to indicate correct operation. The WDI input monitors the port signal and resets the watchdog timer on receipt of a rising edge. If an edge is not received within the required watchdog timeout period, the watchdog circuit initiates a reset cycle and asserts the WDO output (MAX7389 only). The internal watchdog circuits are reset and the watchdog timer restarts at the end of the reset cycle (RST/RST output releases). The WDO output remains asserted until a valid edge is received on the WDI input, signifying correct microprocessor operation. The WDO output can be used as a status indicator either to the microprocessor or to an external device, such as a fault-indicating LED or sounder. The

CLOCK STARTS ON INTERNAL POR (VTH+, VCC RISING). RST RELEASES AFTER THE RESET TIMEOUT PERIOD. RST ASSERTS ON RESET FALLING VOLTAGE (VTH-, VCC FALLING). CLOCK STOPS. RST CONTINUES TO ASSERT UNTIL VCCR.

WDO output is an open-drain output. The power-up condition of the WDO output is high (not asserted). The operation of the watchdog and reset function is illustrated in Figure 2. The watchdog timeout period is set to one of nine possible values by pin strapping WDS1 and WDS2. Each control input has three possible values assigned by connection to GND, VCC, or VCC/2 (see Table 1). One of the assigned values disables the watchdog function and is intended for customer use during test. The watchdog timer is disabled while the RST/RST output is asserted.
Applications Information
Interfacing to a Microcontroller Clock Input
The CLOCK output is a push-pull, CMOS logic output, which directly drives any microprocessor (P) or microcontroller (C) clock input. There are no impedancematching issues when using the MAX7389/MAX7390. Operate the MAX7389/MAX7390 and microcontroller (or other clock input device) from the same supply voltage level. Refer to the microcontroller data sheet for clock-input compatibility with external clock signals. The MAX7389/MAX7390 require no biasing components or load capacitance. When using the MAX7389/ MAX7390 to retrofit a crystal oscillator, remove all biasing components from the oscillator input.

Power-Supply Considerations
The MAX7389/MAX7390 operate with power-supply voltages in the 2.7V to 5.5V range. Power-supply decoupling is needed to maintain the power-supply rejection performance of the devices. Bypass VCC to GND with a 0.1F surface-mount ceramic capacitor. Mount the bypass capacitor as close to the device as possible. If possible, mount the MAX7389/MAX7390 close to the microcontroller's decoupling capacitor so that additional decoupling is not required. A larger-value bypass capacitor is recommended if the MAX7389/MAX7390 are to operate with a large capacitive load. Use a bypass capacitor value of at least 1000 times that of the output load capacitance.

Output Jitter
The MAX7389/MAX7390s' jitter performance is given in the Electrical Characteristics table as a peak-to-peak value obtained by observing the output of the device for 20s with a 500MHz oscilloscope. Jitter measurements are approximately proportional to the period of the output frequency of the device. Thus, a 4MHz part has approximately twice the jitter value of an 8MHz part. The jitter performance of all clock sources degrades in the presence of mechanical and electrical interference. The MAX7389/MAX7390 are immune to vibration, shock, and EMI influences and thus provide a considerably more robust clock source than crystal- or ceramicresonator-based oscillator circuits.
