128Kx8 Nonvolatile SRAM

The bq4013/Y uses an extremely

Features

General Description

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.

➤ Data retention for at least 10

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-

cles of standard SRAM.

years without power

➤ Automatic write-protection during

power-up/power-down cycles

➤ Conventional SRAM operation,

The bq4013/Y requires no external

circuitry and is socket-compatible

with industry-standard SRAMs and

most EPROMs and EEPROMs.

including unlimited write cycles

The control circuitry constantly

monitors the single 5V supply for an

out-of-tolerance condition. When

is unconditionally write-protected to

prevent inadvertent write operation.

At this time the integral energy

source is switched on to sustain the

memory until after V_CCreturns valid.
