■ Industry standard configurations

❐ Operating voltages:

Features

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

❐ Internally organized as 8 K × 8

❐ STORE to QuantumTrap nonvolatile elements initiated

automatically on power-down (AutoStore) or by using I²C

command (SoftwareSTORE) orHSBpin(HardwareSTORE)

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

RECALL) or by I²C command (Software RECALL)

❐ Automatic STORE on power-down with a small capacitor

(except for CY14MX064J1)

• CY14MB064J: V_CC= 2.7 V to 3.6 V

• CY14ME064J: V_CC= 4.5 V to 5.5 V

❐ Industrial temperature

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

❐ Restriction of hazardous substances (RoHS) compliant

Overview

The Cypress CY14MB064J/CY14ME064J combines a 64-Kbit

nvSRAM^[2]with a nonvolatile element in each memory cell. The

memory is organized as 8 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 automatically at power-down

(except for CY14MX064J1). 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 I²C commands.

■ High reliability

❐ Infinite read, write, and RECALL cycles

❐ 1 million STORE cycles to QuantumTrap

❐ Data retention: 20 years at 85 C

■ High speed I²C interface ^[1]

❐ Industry standard 100 kHz and 400 kHz speed

❐ Fast-mode Plus: 1 MHz speed

❐ High speed: 3.4 MHz

❐ Zero cycle delay reads and writes

■ Write protection

❐ Hardware protection using Write Protect (WP) pin

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

■ I²C access to special functions

❐ Nonvolatile STORE/RECALL

❐ 8 byte serial number

❐ Manufacturer ID and Product ID

❐ Sleep mode

Notes

1. The I C nvSRAM is a single solution which is usable for all four speed modes of operation. As a result, some I/O parameters are slightly different than those on

chips which support only one mode of operation. Refer to AN87209 for more details.

2. Serial (I C) nvSRAM is referred to as nvSRAM throughout the datasheet.
