1 / 9 page Discontinued Part 1 CAT93HC46 1-kb High Speed Microwire Serial EEPROM FEATURES s High speed operation: 4 MHz @ 5.0 V s 1.8 to 5.5 volt operation s Selectable x8 or x16 word organization s Sequential Read s Software write protection s Power-up inadvertent write protection s Low power CMOS technology s 1,000,000 program/erase cycles s 100 year data retention s Industrial and extended temperature ranges s 8-Lead PDIP, SOIC, MSOP and TSSOP packages PIN CONFIGURATION DIP Package (P, L) SOIC Package (J, W) DESCRIPTION The CAT93HC46 is a 1-kb Serial EEPROM memory device which is configured as registers of either 16 bits (ORG pin at VCC) or 8 bits (ORG pin at GND). Each register can be written (or read) serially by using the DI (or DO) pin. The CAT93HC46 is manufactured using Catalyst’s advanced CMOS EEPROM floating gate SOIC Package (S, V) 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. © 2005 by Catalyst Semiconductor, Inc.
