Overview

CAT93C46 1 Kb Microwire Serial EEPROM Description The CAT93C46 is a 1 Kb 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 CAT93C46 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: 2 MHz • 1.
8 V to 5.
5 V Supply Voltage Range • Selectable x8 or x16 Memory Organization • Self−Timed Write Cycle with Auto−Clear • Software Write Protection • Power−up Inadvertant Write Protection • Low Power CMOS Technology • 1,000,000 Program/Erase Cycles • 100 Year Data Retention • Industrial Temperature Range • 8−pin PDIP, SOIC, TSSOP and 8−pad TDFN Packages • This Device is Pb−Free, Halogen Free/BFR Free and RoHS Compliant* VCC ORG CS SK DI CAT93C46 DO GND Figure 1.
