CAT25320 32-Kb SPI Serial CMOS EEPROM Description The CAT25320 is a 32 Kb Serial CMOS EEPROM device internally organized as 4096x8 bits. This features a 32byte page write CAT25320 Table 1. ABSOLUTE MAXIMUM RATINGS Parameters Ratings Units Operating Temperature 45 to +130 C 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.
