概述

Description

The M95020-DRMN3TP/K is STMicroelectronics’ M95x-series SPI serial EEPROM. It provides non-volatile storage accessible via a standard 4-wire SPI (CS, SCK, SI, SO). With about 2 Mbit (256 KB) capacity, it supports random and sequential reads, 256-byte page writes, and features such as hardware write protection, deep power-down, and a software reset. The device is offered in an 8-pin package (DRMN3TP/K denotes packaging and tape‑and‑reel). Typical applications include firmware/config data storage, serial numbers, and calibration tables in microcontroller-based systems. For exact electrical/temperature specs, endurance, and timing, consult the ST M95x datasheet and the M95020 product page.

Package

8-pin SO-8 (surface-mount) package for the SPI serial EEPROM.

Pinout

- Pin count: 8 pins (8-pin package)
- Function per pins (typical M95020 I2C EEPROM):
- VCC: supply voltage
- GND: ground
- SDA: I2C data line
- SCL: I2C clock line
- A0, A1, A2: I2C device address inputs
- WP: write-protect input
- Note: M95020 is a 2-kbit (256 x 8) I2C serial EEPROM.

Manufacturer

- Manufacturer: STMicroelectronics.
- What kind of company: A global semiconductor company (headquartered in Geneva, Switzerland) that designs and manufactures integrated circuits, including memory devices, microcontrollers, sensors, and power ICs.

Application

M95020-DRMN3TP/K is a 2 Mbit SPI serial EEPROM for non-volatile storage of calibration data, configuration data, and device IDs. Common application areas include:
- Automotive ECUs
- Industrial control and automation
- Consumer electronics (set-top boxes, displays, peripherals)
- Networking equipment (routers, switches)
- Medical devices and instrumentation
- IoT/smart sensors and edge devices

Equivalent

ST Microelectronics M95020-DRMN3TP/K is a 2‑Mbit SPI Serial EEPROM (8‑pin). Common drop‑in equivalents include Microchip 25AA2048 (2‑Mbit SPI EEPROM). Other vendors offer similar 2‑Mbit SPI EEPROMs; always verify pinout and operating voltage (3.3V/5V) for exact cross‑reference.
