8Kbit I²C EEPROM in an 8-SOIC — what the specs mean for the board
The STMicroelectronics M24C08-DRMN8TP/K is an 8Kbit serial EEPROM organized as 1K x 8 bits, communicating over an I²C bus at up to 1 MHz. The 450 ns access time and 4 ms write cycle time (word or page) set the timing budget for the I²C bus master — the write cycle locks the bus, so firmware must account for the 4 ms window before the next start condition.
Automotive temperature grade and package rework
That makes it suitable for under-hood or engine-adjacent ECUs that see 105°C soak temperatures.
