General Description
The Cypress S29WS512/256/128P are Mirrorbit® Flash products fabricated on 90 nm process technology. These burst mode Flash
devices are capable of performing simultaneous read and write operations with zero latency on two separate banks using separate
data and address pins. These products can operate up to 104 MHz and use a single VCC of 1.7 V to 1.95 V that makes them ideal
for today’s demanding wireless applications requiring higher density, better performance and lowered power consumption.
