TMC
1K/2K/4K/8K/16K-bit
Serial EEPROM for Low Power
Data Sheet
OVERVIEW
The TMC 24A01/24A02/24A04/24A08/24A16 serial EEPROM has a 1,024/2,048/4,096/8,192/16,384-bit
capacity, supporting the standard I2C™-bus serial interface. It is fabricated using TMC’s most advanced
CMOS technology. It has been developed for low power and low voltage applications (1.8 V to 5.5 V). One of its
major feature is a hardware-based write protection circuit for the entire memory area. Hardware-based write
protection is controlled by the state of the write-protect (WP) pin. Using one-page write mode, you can load up to
16 bytes of data into the EEPROM in a single write operation. Another significant feature of the
TMC 24A01/24A02/24A08/24A16 is its support for fast mode and standard mode.
