Document Type: Datasheet for low-power microprocessor (µP) supervisor circuits.

Devices Covered:

️· ASM705: Active LOW reset, watchdog output, and manual reset.
️· ASM706: Active LOW reset, watchdog output, and manual reset. (Lower reset threshold than ASM705)
️· ASM707: Active LOW & HIGH reset with manual reset.
️· ASM708: Active LOW & HIGH reset with manual reset. (Lower reset threshold than ASM707)
️· ASM813L: Active HIGH reset, watchdog output, and manual reset.

Key Features (Common to many):

️· Reset Function: Monitors the voltage of a microcontroller/processor and resets it if the voltage drops below a certain threshold.
️· Watchdog Timer: Resets the processor if the software doesn't "kick" the watchdog within a set time, preventing software lockups.
️· Manual Reset: Allows for a forced reset via a dedicated input pin.
️· Low Power Consumption: Designed for battery-powered or energy-efficient applications.

Variations:

️· Reset Polarity: Devices have either active-LOW or active-HIGH reset outputs.
️· Reset Threshold: Different devices have slightly different reset threshold voltages (e.g., 4.65V vs. 4.40V).
️· Temperature Range: Devices are available in different temperature ranges (0°C to +70°C and -40°C to +85°C).

Package Options:

️· 8-Pin Plastic DIP
️· 8-Pin SO (Small Outline)
️· 8-Pin MicroSO

Ordering Codes:

The datasheet provides detailed ordering codes that specify the part number, reset threshold, temperature range, and package type.

Important Note: The datasheet includes a disclaimer that the information is subject to change.



In essence, this document describes a family of chips designed to ensure the reliable operation of microprocessors by monitoring power and software activity and providing a reset signal if necessary.
