CAT93C46B Datasheet | onsemi

EEPROM Serial 1-Kb Microwire Description The CAT93C46B is a 1- Kb Microwire Serial EEPROM memory device which is configured as either 64 registers of 16 bits (ORG pin at VCC) or 128 registers of 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The CAT93C46B Features a self- timed internal write with auto- clear. On- chip Power- On Reset circuit protects the internal logic against powering up in the wrong state. Features - High Speed Operation: 4 MHz - 1.8 V (1.65 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 Inadvertant 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 UDFN and TDFN Packages - This Device is Pb- Free, Halogen Free/BFR Free and Ro HS pliant† ORG CS SK DI DO CAT93C46B GND Figure 1.
