E only (not recommended for new designs of CAT93C56) PIN FUNCTION Pin Name Function CS Chip Select SK Clock Input DI Serial Data Input DO Serial Data Output VCC Power Supply GND Ground ORG Memory Organization NC No Connection DESCRIPTION The CAT93C56/57 is a 2-Kb CMOS Serial EEPROM device which is organized as either 128 registers of 16 bits (ORG pin at VCC) or 256 registers of 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The CAT93C56/57 features sequential read and self-timed internal write with auto- clear. On-chip Power-On Reset circuitry protects the internal logic against powering up in the wrong state. For Ordering Information details, see page 16. FUNCTIONAL SYMBOL CS SK DI ORG DO CAT93C56 CAT93C57 VCC GND Note: When the ORG pin is connected to VCC, the x16 organization is selected. When it is connected to ground, the x8 pin is selected. If the ORG pin is left unconnected, then am internal pullup device will select the x16 organization |
