Overview

The Cypress CY14X101PA combines a 1 Mbit nvSRAM^[1]with a

full-featured RTC in a monolithic integrated circuit with serial SPI

interface. 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. On power-up, data is restored to

the SRAM from the nonvolatile memory (RECALL operation).

You can also initiate the STORE and RECALL operations

through SPI instruction.
