CAV25320
32-Kb SPI Serial CMOS
EEPROM
Description
The CAV25320 is a 32âKb Serial CMOS EEPROM device
internally organized as 4096x8 bits. This features a 32âbyte 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.
