FEATURES s High speed operation: s Software write protection s Power-up inadvertent write protection s 1,000,000 program/erase cycles s 100 year data retention s mercial, industrial and automotive - 93HC46: 3MHz s Low power CMOS technology s 1.8 to 6.0 volt operation s Selectable x8 or x16 memory organization s Self-timed write cycle with auto-clear s Sequential Read temperature ranges DESCRIPTION The CAT93HC46 is a 1K-bit Serial EEPROM memory devices which is configured as either registers of 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 technology. The device is designed to endure 1,000,000 program/erase cycles and has a data retention of 100 years. The CAT93HC46 is available in 8-pin DIP, 8-pin SOIC or 8-pin TSSOP packages.
