Functional Overview
The Cypress CY14X512Q combines a 512-Kbit nvSRAM[1] with
a nonvolatile element in each memory cell with serial SPI
interface. The memory is organized as 64 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 automati-
cally at power-down (except for CY14X512Q1A). 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.
