Description
MP23AB02BTR is a small serial non-volatile memory device (I2C serial EEPROM). It provides 2 kilobits of storage (approximately 256 bytes) to hold small configuration or calibration data. Key features typically include:
- I2C-compatible two-wire interface
- 2 kb total memory (256 x 8)
- 8-pin package (e.g., SOP/USON variants) with Tape-and-Reel (TR) packaging option
- Voltage supply range usually around 1.8–5.5 V
- Page write (up to 8 bytes) and random/sequential read capability
- Low-power standby mode
Uses: storing device configuration, calibration constants, serial numbers, or other non-volatile data for embedded systems.
Note: exact electrical specs (voltage range, timing, addressing, and package options) can vary by manufacturer and revision. Check the specific datasheet for the MP23AB02BTR you’re using.
