Description
The M95M01-DWDW3TP/K is a 1‑Mbit serial EEPROM from STMicroelectronics. It provides 128 kB of non-volatile storage that retains data when power is removed, ideal for small data like configuration, calibration, or logs.
Interface and organization:
- Two‑wire I2C serial interface (DW denotes dual‑wire).
- Memory is byte-addressable with page‑write capability.
- Device address combines fixed device type bits with A2–A0 pins; supports standard/fast I2C speeds.
Key features (typical):
- Non‑volatile memory with data retention and low‑power modes.
- Random byte reads with a write cycle that requires time to complete.
- Page write support to improve efficiency.
- RoHS‑compliant packaging in an 8‑pin format; temperature/packaging variants indicated by the suffix.
The -DWDW3TP/K suffixes indicate the I2C dual‑wire interface, packaging type, and RoHS/temperature variant.
Note: For exact electrical specs (voltage, timing, endurance, data retention, page size, and pinout) refer to the M95M01‑DWDW3TP/K datasheet.
