Features

Functional Description

■

35 ns and 45 ns access times

The Cypress STK14C88-3 is a 256 Kb fast static RAM with

a nonvolatile element in each memory cell. The embedded

Automatic nonvolatile STORE on power loss

Nonvolatile STORE under Hardware or Software control

Automatic RECALL to SRAM on power up

Unlimited Read/Write endurance

Unlimited RECALL cycles

nonvolatile

elements

incorporate

QuantumTrap^™

technology producing the world’s most reliable nonvolatile

memory. The SRAM provides unlimited read and write

cycles, while independent, nonvolatile data resides in the

highly reliable QuantumTrap cell. Data transfers from the

SRAM to the nonvolatile elements (the STORE operation)

takes place automatically at power down. On power up, data

is restored to the SRAM (the RECALL operation) from the

nonvolatile memory. Both the STORE and RECALL opera-

tions are also available under software control.

1,000,000 STORE cycles

100 year data retention

Single 3.3V+0.3V power supply

Commercial and Industrial Temperatures

32-pin (300mil) SOIC and 32-pin (600 mil) PDIP packages

RoHS compliance
