F CAT93C46 1-Kb Microwire Serial EEPROM FEATURES s High speed operation: 2MHz s 1.8V to 5.5V supply voltage range s Selectable x8 or x16 memory organization s Self-timed write cycle with auto-clear s Software write protection s Power-up inadvertant write protection s Low power CMOS technology s 1,000,000 Program/erase cycles s 100 year data retention s Industrial temperature ranges s RoHS-compliant 8-pin PDIP, SOIC, TSSOP and 8-pad TDFN packages PIN CONFIGURATION PDIP (L) SOIC (V, X) TSSOP (Y) TDFN (VP2) SOIC (W) DESCRIPTION The CAT93C46 is a 1K-bit 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. FUNCTIONAL SYMBOL Note: When the ORG pin is connected to VCC, the x16 organization is selected. When it is connected to ground, the x8 organization is selected. If the ORG pin is left unconnected, then an internal pullup device will select the x16 organization.
