Overview
The CAT25040VI-GT3A is a Serial 4-Kb SPI EEPROM device manufactured by onsemi. This device is internally organized as 512x8 bits and features a 16-byte page write buffer. It supports the Serial Peripheral Interface (SPI) protocol and operates within a supply voltage range of 1.8 V to 5.5 V. The device is enabled through a Chip Select (CS) input and includes necessary bus signals such as a clock input (SCK), data input (SI), and data output (SO) lines. Additionally, it includes a HOLD input for pausing serial communication and write protection mechanisms for both software and hardware protection.
