... Read enable (R) and write enable (W) must both be HIGH dur- ing a retransmit cycle, and then R is used to access the data. The CY7C460, CY7C462, and CY7C464 are fabricated using an advanced 0.8-micron N-well CMOS technology. Input ESD protection is greater than 2000V and latch-up is prevented by careful layout, guard rings, and a substrate bias generator ...
