概述

Description

The M93C76-RDW3TP/K is a Microwire-compatible serial EEPROM from STMicroelectronics. It provides non-volatile storage for microcontrollers and embedded systems.
Key points:
- Capacity and format: memory organized as 1K words × 16 bits (16 Kbits total), i.e., 2 KB.
- Interface: 3-wire Microwire (CS, SK, DI/DO); read and write operations follow the Microwire protocol with an internal write cycle.
- Electrical and temp: typically 4.5–5.5 V supply (some variants tolerate 2.7–5.5 V); industrial temperature grade (-40°C to +125°C) indicated by the K suffix.
- Package: 8-pin package with the RDW3TP/K device/packaging code variant.
- Applications: small configuration data, calibration constants, boot/firmware parameter storage in embedded systems.
- Practical notes: consult the datasheet for exact timing (read/write), endurance, and pinout; the RDW3TP/K suffix denotes a specific package/temperature variant.

Package

8-pin SO-8 (small-outline) package.

Manufacturer

Manufacturer: STMicroelectronics (ST).
What kind of company: A European multinational semiconductor company that designs and manufactures a wide range of integrated circuits and sensors (MCUs, analog/digital ICs, MEMS, etc.), headquartered in Geneva, Switzerland.

Application

Typical applications for the M93C76-RDW3TP/K: non-volatile storage for microcontroller configuration and calibration data; device IDs, serial numbers and traceability codes; small data logging, event counters and status flags; look-up tables and sensor calibration maps; boot/config memory in automotive, industrial controls, consumer electronics and IoT devices. It provides a Microwire-compatible serial EEPROM interface in an 8-pin RoHS package.
