Functional Overview

The Cypress CY14MX064Q combines a 64 Kbit nvSRAM with a

nonvolatile element in each memory cell 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 (except for CY14MX064Q1B). 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.

■ High reliability

❐ Infinite read, write, and RECALL cycles

❐ 1million STORE cycles to QuantumTrap

❐ Data retention: 20 years at 85 C

■ High speed serial peripheral interface (SPI)

❐ 40-MHz clock rate SPI write and read with zero cycle delay

❐ Supports SPI mode 0 (0,0) and mode 3 (1,1)

■ SPI access to special functions

❐ Nonvolatile STORE/RECALL

❐ 8-byte serial number

❐ Manufacturer ID and Product ID

❐ Sleep mode
