16-Mbit (1024 K × 16) nvSRAM

■ Industrial temperature: –40 C to +85 C

Features

■ 165-ball fine-pitch ball grid array (FBGA) package

■ Restriction of hazardous substances (RoHS) compliant

■ 16-Mbit nonvolatile static random access memory (nvSRAM)

❐ 30-ns and 45-ns access times

❐ Logically organized as 1024 K × 16

❐ Hands-off automatic STORE on power-down with only a

small capacitor

Functional Description

The Cypress CY14V116N is a fast SRAM, with a nonvolatile

element in each memory cell. The memory is organized as

1024 K words of 16 bits each. The embedded nonvolatile

elements incorporate QuantumTrap technology, producing the

world’s most reliable nonvolatile memory. The SRAM can be

read and written an infinite number of times. The nonvolatile data

residing in the nonvolatile elements do not change when data is

written to the SRAM. 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.

❐ STORE to QuantumTrap nonvolatile elements is initiated by

software, device pin, or AutoStore on power-down

❐ RECALL to SRAM initiated by software or power-up

■ High reliability

❐ Infinite read, write, and RECALL cycles

❐ 1 million STORE cycles to QuantumTrap

❐ Data retention: 20 years

■ Sleep mode operation

■ Low power consumption

❐ Active current of 75 mA at 45 ns

❐ Standby mode current of 650 A

❐ Sleep mode current of 10 A

■ Operating voltage

❐ Core V_CC= 2.7 V to 3.6 V; I/O V_CCQ= 1.65 V to 1.95 V
