FEATURES
Integrated NV SRAM, real time clock, crystal,
power-fail control circuit and lithium energy
source
Clock registers are accessed identically to the
static RAM; these registers are resident in the
16 top RAM locations
Totally nonvolatile with over 10 years of
operation in the absence of power
Precision power-on reset
Programmable watchdog timer and RTC alarm
BCD coded year, month, date, day, hours,
minutes, and seconds with automatic leap year
compensation valid up to the year 2100
Battery voltage level indicator flag
Power-fail write protection allows for
±10%
VCC power supply tolerance
Lithium energy source is electrically
disconnected to retain freshness until power is
applied for the first time
