Features

Functional Description

■ 35 ns access time

The Cypress STK14C88C is a fast static RAM, with a nonvolatile

element in each memory cell. The memory is organized as 32KB.

The embedded nonvolatile elements incorporate QuantumTrap

technology, producing the world’s most reliable nonvolatile

memory. The SRAM provides infinite 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 operations are also available

under software control.

■ Internally organized as 32K × 8

■ Hands-off automatic STORE on power-down with only a small

capacitor

■ STORE to QuantumTrap nonvolatile elements initiated by

software, device pin, or autostore on power-down

■ RECALL to SRAM initiated by software or power-up

■ Infinite read, write, and RECALL cycles

■ 1 million STORE cycles to QuantumTrap

■ 20-year data retention

■ Single 5 V + 10% operation

■ Industrial and Military temperatures

■ 32-pin CDIP package
