CAV93C66

CAV93C66 EEPROM Serial 4-Kb Microwire - Automotive Grade 1 Description The CAV93C66 is an EEPROM Serial 4−Kb Microwire Automotive Grade 1 device which is organized as either 256 registers of 16 bits (ORG pin at VCC) or 512 registers of 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The device 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 Automotive AEC−Q100 Grade 1 (−40°C to +125°C) Qualified High Speed Operation: 2 MHz 2.5 V to 5.5 V Supply Voltage Range Selectable x8 or x16 Memory Organization Self−timed Write Cycle with Auto−clear Sequential Read Software Write Protection Power−up Inadvertent Write Protection Low Power CMOS Technology 1,000,000 Program/Erase Cycles 100 Year Data Retention 8−lead SOIC and TSSOP Packages These Devices are Pb−Free, Halogen Free/BFR Free, and RoHS Compliant VCC ORG CS SK CAV93C66 DO DI www.onsemi.com SOIC−8 V SUFFIX CASE 751BD TSSOP−8 Y SUFFIX CASE 948AL PIN CONFIGURATIONS CS 1 SK DI DO VCC NC ORG GND SOIC (V), TSSOP (Y) (Top View) Pin Name CS SK DI DO VCC GND ORG NC PIN FUNCTION Function Chip Select Clock Input Serial Data Input Serial Data Output Power Supply Ground Memory Organization No Connection GND Figure 1.
