概述

Description

M24256-DFMN6TP is STMicroelectronics’ 256-kbit I2C serial EEPROM (M24 series). It provides non-volatile storage organized typically as 32K × 8 bits, accessible over the I2C two-wire bus (SCL/SDA) with standard and fast-mode operation.
Key points:
- Interface: I2C two-wire; supports standard and fast-mode I2C.
- Memory: 256 Kbit (32K × 8); suitable for configuration data, calibration, logs, etc.
- Features: byte/word access with page write support, write-cycle polling/acknowledgment, hardware write protection via WP pin, low-power modes.
- Conditions: single-supply operation in a typical voltage range (consult datasheet for exact ranges and timing).
- Package: 8-pin device in the DFMN6 family variant (surface-mount, lead-free).
Usage: ideal for embedded systems needing non-volatile storage with simple I2C interface. For exact electrical characteristics, pinout, timing, and packaging details, refer to the M24256-DFMN6TP datasheet.

Package

An 8-pin surface-mount SOP (SO-8) package; the -TP suffix indicates Tape & Reel packaging.

Pinout

- Pin count: 8 pins.
- Function: 256 Kbit serial SPI flash memory (non-volatile storage) with an SPI interface. Pins typically include CS, SCK, SI (MOSI), SO (MISO), WP#, HOLD#, VCC, and GND. Used to store firmware/data.

Manufacturer

Manufacturer: Renesas Electronics Corporation (Renesas).
Kind of company: A Japanese multinational semiconductor company, one of the world’s largest producers of microcontrollers, memory, analog ICs, and other semiconductor products.

Application

Applications:
- Storing device configuration and calibration data
- Boot/config memory for microcontrollers
- Look-up tables and small firmware/code shadow
- Data logging and event storage
- Used in IoT devices, consumer electronics, automotive/industrial sensors and controllers, and medical equipment requiring compact, non-volatile memory

Equivalent

M24256-DFMN6TP is a 256-kbit SPI serial flash memory. Equivalent parts are other 256-kbit SPI flashes with the same voltage and package from vendors such as Winbond, Macronix, GigaDevice, Puya, and ISSI. For an exact cross-reference, please confirm the supply voltage and package (e.g., 8-pin DFN/SOP) and whether you mean 256 kbit or 256 kB; I’ll provide precise part numbers.
