EEPROM Serial 512-Kb SPI Automotive Grade 1 CAV25512 Description The CAV25512 is a EEPROM Serial 512Kb SPI Automotive Grade 1 device internally organized as 64Kx8 bits. This features a www.onsemi.com 128byte 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 CAV25512 device. The device features software and hardware write protection, including partial as well as full array protection. WLCSP8 TSSOP8 SOIC8 OnChip ECC (Error Correction Code) makes the device suitable C8A SUFFIX Y SUFFIX V SUFFIX CASE 567MB CASE 948AL for high reliability applications.

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 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.

These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AECQ100 and JEDEC test methods. 3. Page Mode, V = 5 V, 25C. CC 4. 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 in order to benefit from the maximum number of write cycles. Table 3. D. C.
