It is qualified to AEC-Q100 Grade 1, meaning the part is tested and guaranteed over the full -40°C to +125°C ambient temperature range — the under-hood band where an ECU sees 105°C on a hot day and still needs margin. The 1.8 V to 5.5 V supply rail lets it sit on a 3.3 V or 5 V logic bus without an external regulator or level shifter on the Vcc pin. The 8-SOIC narrow body (3.90 mm width) is a standard footprint — no board respin needed if the layout already carries an SOIC-8 EEPROM. ## 16 MHz SPI throughput and write-cycle budget The 16 MHz SPI clock delivers a raw read throughput of 16 Mbit/s in single-I/O mode — fast enough to shadow calibration tables or boot code into SRAM without stalling the host controller. The 4 ms page write time (word or page) means a full 64-byte page takes 4 ms to commit; budget this into the firmware update window if the application writes large blocks sequentially. The 512 Kbit density (64K x 8) stores roughly 64 KB of parameter sets, VIN calibration maps, or event logs. For a data logger writing a 32-byte record every second, the 4 ms write cycle leaves plenty of bus time for other SPI slaves. ## Active lifecycle and automotive compliance AEC-Q100 Grade 1 qualification covers the full -40°C to +125°C operating range with the reliability stress tests (preconditioning, temperature cycling, HAST, high-temperature storage) that automotive Tier-1s require for PPAP submission. The part carries the full STMicroelectronics compliance documentation package — RoHS, REACH, and the AEC-Q100 qualification report available on request.","metaTitle":"STMicroelectronics M95512-DRMN3TP/K 512Kbit SPI EEPROM","metaDescription":"STMicroelectronics M95512-DRMN3TP/K 512Kbit SPI EEPROM, 16 MHz clock, 1.8-5.5V supply, -40 to +125°C, 8-SOIC.
