CAT25080, CAT25160 EEPROM Serial 8/16-Kb SPI Description The CAT25080/25160 are a EEPROM Serial 8/16Kb SPI devices internally organized as 1024x8/2048x8 bits. They feature a 32byte page write buffer and support the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In www.onsemi.com addition, the required bus signals are a clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25080/25160 device. These devices feature 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 V + 0.5 V CC Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. 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.
