FM3104-G

Product Summary

The FM3104-G is an Integrated Processor Companion with Memory. It includes the most commonly needed functions for processor-based systems. Major features include nonvolatile memory available in various sizes, real-time clock, low-VDD reset, watchdog timer, nonvolatile event counter, lockable 64-bit serial number area, and general purpose comparator that can be used for an early power-fail (NMI) interrupt or other purpose. The FM3104-G operates from 2.7 to 5.5V. It provides nonvolatile RAM available in sizes including 4Kb, 16Kb, 64Kb, and 256Kb versions. The FM3104-G companion includes commonly needed CPU support functions.
