CAT93C56, CAT93C57 2-Kb Microwire Serial CMOS EEPROM Description The CAT93C56/57 is a 2kb CMOS Serial EEPROM device which is organized as either 128 registers of 16 bits (ORG pin at V ) or 256 CAT93C56, CAT93C57 Table 1. ABSOLUTE MAXIMUM RATINGS Parameters Ratings Units Storage Temperature 65 to +150 C Voltage on Any Pin with Respect to Ground (Note 1) 0.5 to +6.5 V Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. The DC input voltage on any pin should not be lower than 0.5 V or higher than V + 0.5 V. During transitions, the voltage on any pin may CC undershoot to no less than 1.5 V or overshoot to no more than V + 1.5 V, for periods of less than 20 ns. CC Table 2.
