It carries AEC-Q100 automotive qualification and operates over a -40°C to 105°C temperature range. ## 450 ns access time — bus timing headroom The 450 ns access time is the time from the I²C address byte acknowledge to the first data byte on a random read. On a 1 MHz I²C bus (1 µs SCL period), this means the EEPROM releases data within half a clock cycle after the address ACK — no extra wait states needed for most MCU I²C peripherals. The 105°C upper limit covers under-hood and engine-bay ambient temperatures where the PCB sees conducted heat from the engine block. The AEC-Q100 stress tests — extended temperature cycling, high-temperature operating life (HTOL), and electrostatic discharge (HBM/CDM) — are what the automotive OEM requires for PPAP submission. If your BOM targets a passenger-car ECU, this qualification is the gate. ## Write cycle time and page write The write cycle time is 4 ms for a word or a page write. On a 512 Kbit device, the page size is typically 64 bytes (the I²C EEPROM standard for this density). A 4 ms write window means the master must wait 4 ms after the STOP condition on a write before sending the next start — no polling of the ACK is needed if the master inserts a 4 ms delay. No last-time-buy, no NRND flag, no official successor.","metaTitle":"M24512-DRDW8TP/K 512Kbit I²C EEPROM, AEC-Q100, 450 ns","metaDescription":"STMicroelectronics M24512-DRDW8TP/K automotive EEPROM, 512Kbit, I²C, 1 MHz, 1.8-5.5 V, -40 to 105°C, 8-TSSOP.
