CAV25320 32-Kb SPI Serial CMOS EEPROM Description The CAV25320 is a 32−Kb Serial CMOS EEPROM device internally organized as 4096x8 bits. This features a 32−byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAV25320 device. The device features software and hardware write protection, including partial as well as full array protection.

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 VCC + 0.5 V. During transitions, the voltage on any pin may undershoot to no less than −1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns. Table 2.
