Functional Overview
The Cypress CY14V101PS 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 128 Kbytes each consisting of
SRAM and nonvolatile SONOS FLASH 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). The user can initiate the STORE and RECALL
operations through SPI instructions.
