STMicroelectronics M24C08-FDW6TP

Overview

M24C08-FDW6TP from STMicroelectronics is an 8-Kbit I²C-compatible serial EEPROM for low-voltage nonvolatile data storage. The memory is organized as 1024 × 8 bits and is designed for configuration data, board identification, calibration constants, service records, and small persistent data blocks in embedded systems operating from the M24C08-F low-voltage supply range.

For engineers reviewing the M24C08-FDW6TP datasheet, M24C08-FDW6TP pinout, M24C08-FDW6TP application, or M24C08-FDW6TP equivalent, this EEPROM is most relevant for MCU configuration storage, product ID memory, sensor calibration data, industrial module settings, consumer electronics parameters, and low-power embedded products requiring TSSOP8 assembly, I²C serial access, 16-byte page write operation, hardware write control, and tape-and-reel production handling.

Technical Context

M24C08-FDW6TP stores 8 Kbits of electrically erasable nonvolatile memory and communicates through SDA and SCL on an I²C-compatible bus. The device supports byte write, 16-byte page write, current-address read, random read, and sequential read operations, allowing a host microcontroller to store small data records without using a parallel address or data bus.

The 8-Kbit density uses internal memory block addressing in the I²C control byte, while the E2 pin provides a hardware address input for bus address planning. The WC pin provides hardware write-control protection, which is useful when configuration, calibration, or production-programmed data must remain readable while accidental EEPROM write cycles are inhibited.

Key Specifications

Pinout & Package

M24C08-FDW6TP is supplied in an 8-lead TSSOP package. The TSSOP8 format reduces EEPROM footprint compared with wider SO8 packages while retaining the standard serial-memory pin structure for address selection, ground, I²C data, I²C clock, write control, and supply, making it practical for compact MCU boards and high-density control modules.

Key Features

• 8-Kbit serial EEPROM organized as 1024 × 8 bits for compact nonvolatile storage.

Applications

Equivalent & Alternatives

When evaluating M24C08-FDW6TP equivalent devices, engineers should compare EEPROM density, package footprint, voltage option, I²C address behavior, page size, write-control pin handling, timing, endurance and retention requirements, temperature range, and whether the firmware depends on the 8-Kbit internal block-addressing structure.

Compared with M24C08-FMN6TP, M24C08-FDW6TP keeps the same EEPROM density and serial-memory function while using a smaller TSSOP8 package. M24C08-FDW6TP vs M24C04-FDW6TP or M24C16-FDW6TP selection depends mainly on required nonvolatile capacity, firmware address mapping, board footprint, and programming workflow.

FAQ

What is M24C08-FDW6TP used for?

M24C08-FDW6TP is used to store small nonvolatile data blocks such as configuration bytes, board identification data, calibration constants, service settings, display information, and production-programmed parameters. It connects to a host controller through an I²C-compatible serial interface and retains data after power is removed.

How much memory does M24C08-FDW6TP provide?

M24C08-FDW6TP provides 8 Kbits of EEPROM memory organized as 1024 bytes. This capacity is suitable for compact tables, identification records, calibration data, and configuration storage. Firmware should account for the M24C08 memory block addressing used by the 8-Kbit device density.

What interface does M24C08-FDW6TP use?

M24C08-FDW6TP uses an I²C-compatible two-wire serial interface with SDA and SCL pins. SDA is a bidirectional open-drain data line and SCL is the serial clock input from the host controller. External pull-up resistors are required on the I²C bus according to bus voltage, capacitance, and speed.

What package is used by M24C08-FDW6TP?

M24C08-FDW6TP uses a TSSOP8 package. The DW package code identifies the TSSOP8 package option, while the TP suffix identifies tape-and-reel packing. This package is useful for compact EEPROM layouts where a smaller footprint than SO8 is preferred.

What do the NC and E2 pins mean on M24C08-FDW6TP?

M24C08-FDW6TP uses pin 1 and pin 2 as no-connect pins, while pin 3 is E2, the available hardware address input. The remaining addressing needed for the 8-Kbit memory array is handled internally through memory block selection in the I²C control byte, so firmware addressing must match the M24C08 structure.

How does the WC pin work on M24C08-FDW6TP?

The WC pin on M24C08-FDW6TP provides hardware write-control protection. When driven to the protected state, EEPROM write operations are inhibited while read operations remain available. This is useful after production programming, calibration, or final configuration because it reduces accidental modification of stored data.

What is the difference between M24C08-FDW6TP and M24C08-FMN6TP?

M24C08-FDW6TP and M24C08-FMN6TP are both STMicroelectronics M24C08-F 8-Kbit I²C EEPROM options. The main difference is package format: M24C08-FDW6TP uses TSSOP8, while M24C08-FMN6TP uses SO8. The correct choice depends on PCB footprint, assembly process, and replacement compatibility.

What are common M24C08-FDW6TP alternatives?

Common comparison options include M24C08-FMN6TP for the same 8-Kbit density in SO8, M24C04-FDW6TP when 4-Kbit capacity is enough, and M24C16-FDW6TP when 16-Kbit capacity is needed. These options require package, address mapping, firmware driver, and memory-size comparison before substitution.
