Functional Description

The Cypress CY14C064I/CY14B064I/CY14E064I combines a

64-Kbit nvSRAM^[2]with a full-featured RTC in a monolithic

integrated circuit with serial I²C interface. 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.

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.

❐ Zero cycle delay reads and writes

■ Write protection

❐ Hardware protection using Write Protect (WP) pin

❐ Software block protection for one-quarter, one-half, or entire

array

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 will be referred to as nvSRAM throughout the datasheet.
