Overview

The Cypress CY14C101J/CY14B101J/CY14E101J combines a

1-Mbit nvSRAM^[2]with a nonvolatile element in each memory

cell. The memory is organized as 128 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 CY14X101J1). 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.
