Features

■ 512-Kbit nonvolatile static random access memory (nvSRAM)

• CY14C512Q: V_CC= 2.4 V to 2.6 V

• CY14B512Q: V_CC= 2.7 V to 3.6 V

❐ Industrial temperature

❐ 8- and 16-pin small outline integrated circuit (SOIC) package

❐ Restriction of hazardous substances (RoHS) compliant

internally organized as 64 K × 8

❐ STORE to QuantumTrap nonvolatile elements initiated

automatically on power-down (AutoStore) or by using SPI

instruction (Software STORE) or HSB pin (Hardware

STORE)

❐ RECALL to SRAM initiated on power-up (Power-Up

RECALL) or by SPI instruction (Software RECALL)

Functional Overview

❐ Support automatic STORE on power-down with a small

capacitor (except for CY14X512Q1A)

The Cypress CY14X512Q combines a 512-Kbit nvSRAM^[1]with

a nonvolatile element in each memory cell with serial SPI

interface. The memory is organized as 64 K words of 8 bits each.

The embedded nonvolatile elements incorporate the

QuantumTrap technology, creating the world’s most reliable

nonvolatile memory. The SRAM provides infinite read and write

cycles, while the QuantumTrap cells provide highly reliable

nonvolatile storage of data. Data transfers from SRAM to the

nonvolatile elements (STORE operation) takes place automati-

cally at power-down (except for CY14X512Q1A). On power-up,

data is restored to the SRAM from the nonvolatile memory

(RECALL operation). You can also initiate the STORE and

RECALL operations through SPI instruction.

■ High reliability

❐ Infinite read, write, and RECALL cycles

❐ 1million STORE cycles to QuantumTrap

❐ Data retention: 20 years at 85 C

■ 40-MHz, and 104-MHz High-speed serial peripheral interface

(SPI)

❐ 40-MHz clock rate SPI write and read with zero cycle delay

❐ 104-MHz clock rate SPI write and SPI read (with special fast

read instructions)

❐ Supports SPI mode 0 (0,0) and mode 3 (1,1)

■ SPI access to special functions

❐ Nonvolatile STORE/RECALL

❐ 8-byte serial number
