PIN DESCRIPTION Pin Number ASM705/706 ASM707/708 ASM813L DIP/ SO MicroSO DIP/ SO MicroSO DIP/ SO MicroSO Name Function 1 3 1 3 1 3 MR Manual reset input. The active LOW input triggers a reset pulse. A 250 mA pull−up current allows the pin to be driven by TTL/CMOS logic or shorted to ground with a switch. 2 4 2 4 2 4 VCC +5 V power supply input. 3 5 3 5 3 5 GND Ground reference for all signals. 4 6 4 6 4 6 PFI Power−fail input voltage monitor. With PFI less than 1.25 V, PFO goes LOW. Connect PFI to Ground or VCC when not in use. 5 7 5 7 5 7 PFO Power−fail output. The output is active LOW and sinks current when PFI is less than 1.25 V. 6 8 − − 6 8 WDI Watchdog input. WDI controls the internal watchdog timer. A HIGH or LOW signal for 1.6 sec at WDI allows the internal timer to run−out, setting WDO LOW. The watchdog function is disabled by floating WDI or by connecting WDI to a high impedance three−state buffer. The internal watchdog timer clears when: RESET is asserted; WDI is three− stated; or WDI sees a rising or falling edge. − − 6 8 − − NC Not Connected. 7 1 7 1 − − RESET Active LOW reset output. Pulses LOW for 200 ms when triggered, and stays LOW whenever VCC is below the reset threshold. RESET remains LOW for 200 ms after VCC rises above the reset threshold or MR goes from LOW to HIGH. A watchdog timeout will not trigger RESET unless WDO is connected to MR. 8 2 − − 8 2 WDO Watchdog output. WDO goes LOW when the 1.6 second internal watchdog timer times−out and does not go HIGH until the watchdog is cleared. In addi- tion, when VCC falls below the reset threshold, WDO goes LOW. Unlike RESET, WDO does not have a minimum pulse width and as soon as VCC exceeds the reset threshold, WDO goes HIGH with no delay. − − 8 2 7 1 RESET Active HIGH reset output. The inverse of RESET. The ASM813L only has a RESET output. |
