FEATURES
Converts CMOS SRAM into nonvolatile
memory
Unconditionally write-protects SRAM when
VCC is out of tolerance
Automatically switches to battery backup
supply when VCC power failure occurs
Flexible memory organization
- Mode 0: 4 banks with 1 SRAM each
- Mode 1: 2 banks with 2 SRAMs each
- Mode 2: 1 bank with 4 SRAMs each
Monitors voltage of a lithium cell and
provides advanced warning of impending
battery failure
Signals low-battery condition on active low
Battery Warning output signal
Resets processor when power failure occurs
and holds processor in reset during system
power-up
Optional 5% or 10% power-fail detection
16-pin PDIP, 16-pin SO and 20-pin TSSOP
packages
Industrial temperature range of -40°C to
+85°C
