M95128-DRMN3TP/K

The M95128-DRMN3TP/K is a 128‑Kbit SPI serial EEPROM manufactured by STMicroelectronics, providing non‑volatile memory storage in an industry‑standard SOP‑8 surface‑mount package. It belongs to the M95128 family and operates over a wide supply voltage range (typically 1.8 V to 5.5 V), supporting high‑speed SPI‑compatible serial communication with byte and page write capability. The device is organized as 16,384 × 8 bits and incorporates a hardware write‑protect pin and software write‑protection features for data integrity. The “/K” suffix denotes compliance with AEC‑Q100 automotive qualification standards, assuring extended temperature operation and enhanced reliability metrics suitable for harsh environments.

Typical applications include parameter storage and configuration data retention in industrial controllers, sensor calibration tables in aerospace guidance systems, and event logging in defense communication equipment. The EEPROM’s robust endurance and long data retention make it a candidate for high‑reliability embedded designs where data must survive power cycles and extended mission profiles. From a procurement perspective, the AEC‑Q100 qualification provides assurance of controlled lifecycle management and ongoing product support from STMicroelectronics, reducing the risk of premature obsolescence in programs with long qualification cycles. Engineers specifying this part for industrial, aerospace, or automotive applications benefit from a supply chain backed by ST’s long‑term availability programs for automotive‑grade EEPROMs, though buyers should verify current production status for their specific temperature grade and package variant.
