FEATURES
§ 128 kbytes of user NV RAM
§ Integrated NV SRAM, real time clock,
crystal, power-fail control circuit and lithium
energy source
§ Totally nonvolatile with over 10 years of
operation in the absence of power
§ Watchdog timer restarts an out-of-control
processor
§ Alarm function schedules real-time related
activities such as system wakeup
§ Programmable interrupts and square wave
output
§ All registers are individually addressable via
the address and data bus
§ Interrupt signals active in power-down mode
