Automotive-grade 2 Kbit I2C EEPROM
The STMicroelectronics M24C02-DRMN8TP/K is a 2 Kbit serial EEPROM organized as 256 x 8 bits, accessed through an I²C interface at clock frequencies up to 1 MHz.
1 MHz I²C bus — fast enough for parameter logging
The 1 MHz clock frequency places this part in the fast-mode-plus tier of the I²C specification. For an ECU that logs calibration trims, fault codes, or VIN data at power-up, the 450 ns access time and 4 ms page write cycle keep the bus transaction short enough that the main controller is not stalled waiting for the EEPROM to finish. The 256-byte page boundary means a full 2 Kbit write completes in two page-write cycles, each taking 4 ms.
The ROHS3 compliance is current and covers the EU RoHS recast.
The mounting is surface-mount only; the shipping options include Tape & Reel and Cut Tape, so it feeds into a standard pick-and-place line without a reel change.
