General Description
The CMOS bq4013/Y is a nonvolatile
1,048,576-bit static RAM organized as
131,072 words by 8 bits. The integral
control circuitry and lithium energy
source provide reliable nonvolatility
coupled with the unlimited write cy-
clesofstandardSRAM.
The control circuitry constantly
monitors the single 5V supply for an
out-of-tolerance condition.
V
CC
falls out of tolerance, the SRAM
is unconditionally write-protected to
prevent inadvertent write operation.
When
At this time the integral energy
source is switched on to sustain the
memory until after V
CC
returns valid.
The bq4013/Y uses an extremely
low standby current CMOS SRAM,
coupled with a small lithium coin
cell to provide nonvolatility without
long write-cycle times and the
write-cycle limitations associated
with EEPROM.
The bq4013/Y requires no external
circuitry and is socket-compatible
with industry-standard SRAMs and
most EPROMs and EEPROMs.
