Features

Functional Description

■ 25 ns and 45 ns access times

The Cypress CY14B256LA is a fast static RAM, with a

nonvolatile element in each memory cell. The memory is

organized as 32 K bytes of 8 bits each. 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 32 K × 8 (CY14B256LA)

■ 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 3 V +20% to –10% operation

■ Industrial temperature

■ 44-pin thin small outline package (TSOP) Type II, 48-pin shrunk

small outline package (SSOP), and 32-pin small-outline

integrated circuit (SOIC) packages

■ Pb-free and restriction of hazardous substances (RoHS)
