4 Kbit I²C EEPROM in 8-SOIC — supply and timing fit
The STMicroelectronics M24C04-RMN6TP is a 4 Kbit serial EEPROM organized as 512 x 8 bits, accessed over an I²C interface at up to 400 kHz. The 900 ns access time and 5 ms write cycle (word or page) are typical for this density class — the bus timing budget is straightforward for any MCU with a hardware I²C peripheral.
Tape & Reel — what the procurement buyer sees
The active lifecycle status means ST continues to manufacture it — no last-time-buy clock ticking, no forced redesign for a drop-in substitute.
The wide supply range is the single most important compatibility spec for a BOM line. At 3.3 V the part runs within its nominal window; at 5 V it still meets the 400 kHz clock and 900 ns access without derating.
