CAT25M02 EEPROM Serial 2-Mb SPI Description The CAT25M02 is a EEPROM Serial 2Mb SPI device internally organized as 256Kx8 bits. This features a 256byte 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 www.onsemi.com 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 CAT25M02 device. The device features software and hardware write protection, including partial as well as full array protection. OnChip ECC (Error Correction Code) makes the device suitable SOIC8 WLCSP8 V SUFFIX C8A SUFFIX for high reliability applications.

ABSOLUTE MAXIMUM RATINGS Parameters Ratings Units Operating Temperature 40 to +125 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 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.

The device uses ECC (Error Correction Code) logic with 6 ECC bits to correct one bit error in 4 data bytes. Therefore, when a single byte has to be written, 4 bytes (including the ECC bits) are reprogrammed. It is recommended to write by multiple of 4 bytes located at addresses 4N, 4(N+1), 4(N+2), 4(N+3), in order to benefit from the maximum number of write cycles. 4. These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AECQ100 and JEDEC test methods. www.onsemi.com 2
