... Read Enable (R) and Write Enable (W) must both be HIGH during a retransmit cycle, and then R is used to access the data. The CY7C460A, CY7C462A, CY7C464A, and CY7C466A are fabricated using Cypress’s advanced 0.5µ RAM3 CMOS tech- nology. Input ESD protection is greater than 2000V and latch-up is prevented by careful layout and the use of guard rings ...

... The retransmit feature is beneficial when transferring packets of data. It enables the receipt of data to be acknowledged by the receiver and retransmitted if necessary. The retransmit after the rising RHF (RT) input is active in the standalone and width expansion modes.
