Overview
The CAT25020VI-GT3JN is a 2-Kb SPI Serial CMOS EEPROM device manufactured by onsemi. This device is part of the CAT25010/20/40 series, which are internally organized as 256x8 bits. It features a 16-byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input and uses clock (SCK), data input (SI), and data output (SO) lines for communication. Additionally, it includes a HOLD input to pause any serial communication.
