Overview

The Cypress CY14C101I/CY14B101I/CY14E101I combines a

1-Mbit nvSRAM^[1]with a full-featured RTC in a monolithic

integrated circuit with serial I²C interface. The memory is

organized as 128 K words of 8 bits each. The embedded nonvol-

atile 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.

On power-up, data is restored to the SRAM from the nonvolatile

memory (RECALL operation). The STORE and RECALL opera-

tions can also be initiated by the user through I²C commands.

❐ 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
