3 S93WD462/S93WD463 2029 2.2 1/23/01 SUMMIT MICROELECTRONICS, Inc. Instructions, addresses, and write data are clocked into the DI pin on the rising edge of the clock (SK). The DO pin is normally in a high impedance state except when reading data from the device, or when checking the ready/busy status after a write operation.
4 S93WD462/S93WD463 2029 2.2 1/23/01 SUMMIT MICROELECTRONICS, Inc. Erase Upon receiving an ERASE command and address, the CS (Chip Select) pin must be deselected for a minimum of 250ns (t CSMIN ). The falling edge of CS will start the auto erase cycle of the selected memory location.
