CAT93C46R 1 kb Microwire Serial EEPROM Description The CAT93C46R is a 1 kb CMOS Serial EEPROM device which is organized as either 64 registers of 16 bits or 128 registers of 8 bits, as CAT93C46R Table 1. ABSOLUTE MAXIMUM RATINGS Parameter Value 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.
