Functional Overview
The Cypress CY14V101QS combines a 1-Mbit nvSRAM with a
QPI interface. The QPI allows writing and reading the memory in
either a single (one I/O channel for one bit per clock cycle), dual
(two I/O channels for two bits per clock cycle), or quad (four I/O
channels for four bits per clock cycle) through the use of selected
opcodes.
The memory is organized as 128Kbytes each consisting of
SRAM and nonvolatile SONOS Quantum Trap cells. The SRAM
provides infinite read and write cycles, while the nonvolatile cells
provide highly reliable storage of data. Data transfers from
SRAM to the nonvolatile cells (STORE operation) take place
automatically at power-down. On power-up, data is restored to
the SRAM from the nonvolatile cells (RECALL operation). You
can also initiate the STORE and RECALL operations through
SPI instructions.
