512-Kbit (64 K × 8) Serial (SPI) nvSRAM

512-Kbit (64

K × 8) Serial (SPI) nvSRAM

■ Industry standard configurations

❐ Industrial temperature

❐ CY14B512Q1 has identical pin configuration to industry

standard 8-pin NV memory

Features

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

❐ Internally organized as 64 K × 8

❐ 8-pin dual flat no-lead (DFN) package and 16-pin small

❐ STORE to QuantumTrap nonvolatile elements initiated

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

HSB pin (Hardware STORE) or SPI instruction (Software

STORE)

outline integrated circuit (SOIC) package

❐ Restriction of hazardous substances (RoHS) compliant

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

Functional Overview

RECALL) or by SPI instruction (Software RECALL)

The

Cypress

CY14B512Q1/CY14B512Q2/CY14B512Q3

❐ Automatic STORE on power-down with a small capacitor

(except for CY14B512Q1)

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 cell provides highly reliable nonvolatile storage of

data. Data transfers from SRAM to the nonvolatile elements

(STORE operation) takes place automatically at power-down

(except for CY14B512Q1). On power-up, data is restored to the

SRAM from the nonvolatile memory (RECALL operation). The

STORE and RECALL operations can also be initiated by the user

through SPI instruction.

■ High reliability

❐ Infinite read, write, and RECALL cycles

❐ 1 million STORE cycles to QuantumTrap

❐ Data retention: 20 years

■ High speed serial peripheral interface (SPI)

❐ 40 MHz clock rate

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

■ Write protection

❐ Hardware protection using Write Protect (WP) pin

❐ Software protection using Write Disable instruction

❐ Software block protection for 1/4,1/2, or entire array

Configuration

■ Low power consumption

❐ Single 3 V +20%, –10% operation

❐ Average active current of 10 mA at 40 MHz operation
