CAT93C76B EEPROM Serial 8-Kb Microwire Description The CAT93C76B is an 8Kb Microwire Serial EEPROM memory device which is configured as either registers of 16 bits (ORG pin at www.onsemi.com V or Not Connected) or 8 bits (ORG pin at GND). Each register can CC be written (or read) serially by using the DI (or DO) pin. The CAT93C76B is manufactured using ON Semiconductors advanced CMOS EEPROM floating gate technology. The device is designed to SOIC8 UDFN8 endure 1,000,000 program/erase cycles and has a data retention of 100 V SUFFIX HU4 SUFFIX years. The device is available in 8pin PDIP, SOIC, TSSOP, MSOP CASE 751BD CASE 517AZ and 8pad UDFN packages. Features High Speed Operation: 4 MHz (5 V), 2 MHz (1.8 V) 1.8 V (1.65 V*) to 5.5 V Supply Voltage Range PDIP8 TSSOP8 MSOP8 L SUFFIX Y SUFFIX Z SUFFIX Selectable x8 or x16 Memory Organization CASE 646AA CASE 948AL CASE 846AD Selftimed Write Cycle with Autoclear Software Write Protection PIN CONFIGURATION Powerup Inadvertant Write Protection 1 Low Power CMOS Technology V CS CC SK NC 1,000,000 Program/Erase Cycles DI ORG DO 100 Year Data Retention GND Industrial and Extended Temperature Ranges PDIP (L), SOIC (V), TSSOP (Y), UDFN (HU4), MSOP (Z) Sequential Read (Top View) 8pin PDIP, SOIC, TSSOP, MSOP and 8Pad UDFN Packages This Device is PbFree, Halogen Free/BFR Free and RoHS PIN FUNCTION Compliant Pin Name Function V CS Chip Select CC SK Serial Clock Input ORG DI Serial Data Input DI DO Serial Data Output CS CAT93C76B DO V Power Supply CC SK GND Ground ORG Memory Organization GND NC No Connection Figure 1. Functional Symbol NOTE: When the ORG pin is connected to V , the CC x16 organization is selected. When it is connected to ground, the x8 organization is selected. If the ORG pin *CAT93C76BxxxxL (T = 20 C to +85 C) A is left unconnected, then an internal pullup device will select the x16 organization.
