Memory chip

The CAT24C08 is an EEPROM serial 8-Kb I2C device internally organized as 64 pages of 16 bytes each. The device supports standard (100 kHz) protocol as well as fast (400 kHz) I2C protocol. Data is written by providing a start address, then loading 1 to 16 consecutive bytes into the page write cache, and then writing all the data to non-volatile memory in an internal write cycle. The way to read data is: provide the start address, then move out the data in order, and automatically increment the internal address count at the same time. External address pins enable addressing of up to two CAT24C08 devices on the same bus.

1.7-5.5V wide working voltage

The CAT25040 is an EEPROM serial 4-Kb SPI device internally organized as 512x8 bits. ON Semiconductor's advanced CMOS technology significantly reduces device power requirements. It has a 16-byte write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through chip select (CS). Also, the must-have bus signals are the clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input can be used to suspend any serial communication with the CAT25040 device. The device features hardware and software write protection, including partial protection and full array protection.
