Product Overview

The STMicroelectronics M95640-DRMN3TP/K is a 64Kbit (8,192 x 8) serial EEPROM device that operates over a wide voltage range of 1.8V to 5.5V, making it compatible with both low‑power and legacy 5V systems. It features an SPI (Serial Peripheral Interface) bus that supports up to 20MHz clock frequency, enabling fast read/write operations for configuration data, parameter storage, and calibration tables.

The device is organized in 256‑byte pages, with a 5ms (max) write cycle time and page write capability of up to 32 bytes. The “K” suffix denotes automotive AEC‑Q100 Grade 1 qualification, with an extended operating temperature range of -40°C to +125°C. Housed in a compact 8‑pin SOIC (150mil) package (DRMN3TP/K), it is ideal for harsh automotive environments, industrial controls, and battery‑management systems. With 4 million write cycles and 200‑year data retention, the M95640‑DRMN3TP/K delivers the extreme endurance and reliability required for mission‑critical automotive electronics.

⚡ SPI Performance & Write Protection

SPI Clock Speed

20 MHz @ 2.5‑5.5V
10 MHz @ 1.8‑2.5V
Read throughput up to 2.5 MB/s

Write Cycle

5ms max (including page write)
