Overview
The Cypress CY14X064PA combines a 64 Kbit nvSRAM[1] with
a full-featured RTC in a monolithic integrated circuit with serial
SPI 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).
You can also initiate the STORE and RECALL operations
through SPI instruction.
