E) 2K-Bit Microwire Serial EEPROM FEATURES I High speed operation: 1MHz I Low power CMOS technology I 1.8 to 5.5 volt operation I Selectable x8 or x16 memory organization I Self-timed write cycle with auto-clear I Software write protection I Sequential read I Power-up inadvertant write protection I 1,000,000 Program/erase cycles I 100 year data retention I Commercial, industrial and automotive temperature ranges I RoHS-compliant packages PIN CONFIGURATION DIP Package (L) SOIC Package (W) using Catalyst’s advanced CMOS EEPROM floating gate technology. The devices are designed to endure 1,000,000 program/erase cycles and has a data reten- tion of 100 years. The devices are available in 8-pin DIP, SOIC, TSSOP and 8-pad TDFN packages. DESCRIPTION The CAT93C56/57 are 2K-bit Serial EEPROM memory devices which are 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 CAT93C56/57 are manufactured SOIC Package (V) SOIC Package (X) TSSOP Package (Y) TDFN Package (ZD4) Bottom View FUNCTIONAL SYMBOL Note: When the ORG pin is connected to VCC, the x16 organiza- tion 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.
