Overview

Description

24FC512-I/ST is STMicroelectronics’ 512‑Kbit I2C Serial EEPROM (64 KBytes) with industrial temperature range (-40 to +85°C). It provides a non-volatile memory on the I2C two‑wire bus.
Key features
- Capacity: 512 Kbit (64 KB); 16‑bit addressing (two address bytes)
- Interface: I2C, up to 400 kHz (Fast mode)
- Memory organization: single 64K-byte array; A0–A2 pins for device addressing; WP for write protection
- Page write: up to 128 bytes per write; random and sequential read support
- Write cycle: typically 3–5 ms
- Packages: 8‑pin packages (SOIC/DIP/SOT variants)
Typical usage
- Store configuration data, calibration tables, logs, or small datasets
- Multiple devices on one bus (up to 8 with A0–A2 addressing)
Basic operation
- Write: device address (R/W=0), two-byte memory address, data, stop
- Read: set address, then restart with R/W=1 to fetch data
For specifics (pinout, timing, and electrical characteristics) refer to the ST 24FC512-I/ST datasheet.

Package

8-pin SOIC (D) package (SO-8) for the 24FC512-I/ST.

Pinout

- Pin count: 8 pins (DIP-8/SO-8).
- Function: ST24FC512-I/ST is an I2C 512 kbit serial EEPROM (64 KB). It uses a two-wire I2C interface (SDA, SCL) with A0–A2 address pins to set the device address, 16-bit memory addressing (two-byte word address), and a WP (write-protect) input. Pinout typically: 1 A0, 2 A1, 3 A2, 4 GND, 5 SDA, 6 SCL, 7 WP, 8 VCC.

Manufacturer

- Manufacturer: STMicroelectronics (ST)
- What kind of company: A multinational semiconductor company that designs and manufactures integrated circuits and electronic components (memory, microcontrollers, sensors, analog ICs, etc.).

Application

24FC512-I/ST is a 512-kbit I2C serial EEPROM. It offers non-volatile storage for device configuration and calibration data, IDs/serial numbers, security keys, logs, firmware/config tables, and look-up tables in microcontroller-based designs. Suitable for automotive, industrial equipment, consumer electronics, medical devices, smart meters, and other space-constrained applications needing reliable, low-power data retention with an I2C interface.
