CAV25512
512-Kb SPI Serial CMOS
EEPROM
Description
The CAV25512 is a 512−Kb Serial CMOS EEPROM device
internally organized as 64Kx8 bits. This features a 128−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 CAV25512 device. The device
features software and hardware write protection, including partial as
well as full array protection.
On−Chip ECC (Error Correction Code) makes the device suitable
for high reliability applications.

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 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.

2. These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC−Q100
and JEDEC test methods.
3. Page Mode, VCC = 5 V, 25°C.
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 re−programmed. It is recommended to write by multiple of 4 bytes in order to benefit
from the maximum number of write cycles.
