SP813MCU

The SP813MCU is one member of the SP813M series.The SP813M series is a family of microprocessor (P) supervisory circuits that integrate myriad components involved in discrete solutions which monitor power-supply and battery in P and digital systems. The SP813M series will significantly improve system reliability and operational efficiency when compared to solutions obtained with discrete components. The features of the SP813M series include a watchdog timer,a P reset, a Power Fail Comparator, and a manual-reset input.

Features of the SP813MCU are:(1)independent watchdog timer - 1.6s timeout; (2)60A maximum supply current; (3)debounced TTL/CMOS manual reset input; (4)RESET asserted down to Vcc = 1V; (5)voltage monitor for power failure or low battery warning; (6)available in 8-pin PDIP, NSOIC, and SOIC packages; (7)functionally compatible to industry standard 1232 series.The SP813M series is ideal for applications in automotive systems, computers, controllers, and intelligent instruments. The SP813M series is an ideal solution for systems in which critical monitoring of the power supply to the P and related digital components is demanded.

The absolute maximum ratings of the SP813MCU can be summarized as:(1)Vcc:-0.3 to 6.0V;(2)input current:20mA;(3)storage temperature:-365 to 160;(4)lead temperature (soldering, 10s):+300;(5).This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability and cause permanent damage to the device.The SP813M series is a microprocessor (P) supervisory circuit that monitors the power supplied to  digital circuits such as microprocessors, microcontrollers, or memory.The series is an ideal solution for portable, battery-powered equipment that requires power supply monitoring. Implementing this series will reduce the number of components and overall complexity.  The watchdog functions of this product family will continuously oversee the operational status of a system.
