CAT93C56

CAT93C56, CAT93C57 2-Kb Microwire Serial CMOS EEPROM CAT93C57 Not Recommended for New Designs: Replace with CAT93C56 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. Features High Speed Operation: 2 MHz 1.8 V to 5.5 V Supply Voltage Range Selectable x8 or x16 Memory Organization Sequential Read Software Write Protection Power−up Inadvertent Write Protection Low Power CMOS Technology 1,000,000 Program/Erase Cycles 100 Year Data Retention Industrial and Extended Temperature Ranges 8−pin PDIP, SOIC, TSSOP and 8−pad TDFN Packages These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant VCC ORG CS SK DI CAT93C56 CAT93C57 DO GND Figure 1. Functional Symbol 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 an internal pullup device will select the x16 organization. http://onsemi.com SOIC−8 V or W SUFFIX CASE 751BD SOIC−8 EIAJ X SUFFIX CASE 751BE TDFN−8 VP2 SUFFIX CASE 511AK PDIP−8 L SUFFIX CASE 646AA TSSOP−8 Y SUFFIX CASE...
