Features

Functional Description

■ 35 ns access time

The Cypress STK14C88C-3 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

■ Power supply operation

❐ Single 3.0 V + 20%, -10% operation for Industrial

Temperature

❐ Single 3.3 V + 0.3 V operation for Military Temperature

■ Industrial and Military temperatures

■ 32-pin CDIP package
