Product Descriptions

A plug-in EPRoM storage module, including three versions HW-669A (without chip), HW-669B(AT24C256),HW-669C(AT24C128), Other microcontrollers can communicate through the I2C protocol and write data to EEPROM (electrically erasable and programmable memory), which remains stored even after power failure. The A0-A2 switchable jumper cap on the board selects the corresponding I2 address, while the WP jumper cap prevents writing to the memory. The EEPROM series includes models such as AT24C128 (128Kb), AT24C256 (256Kb), AT24C512 (512b), and AT24C1024 (1024 Kb) with integrated 8P pins and pluggable chips, requiring larger capacity EEPROM chips to be inserted.
