Q1: What are the key features of the STMicroelectronics M24C04-WMN6TP?
A: The M24C04-WMN6TP is a 4 Kbit (512-byte) serial EEPROM with an I²C interface supporting data rates up to 400 kHz. It works from a 2.5 V to 5.5 V supply voltage and includes a 16-byte page write structure. It supports random and sequential read modes, and both byte and page write operations with a typical write time of 5 ms. The device operates from -40°C to +85°C, provides more than 4 million write cycles, over 200 years of data retention, and includes write protection as well as enhanced ESD and latch-up protection.
Q2: What is the M24C04-WMN6TP used for?
A: It is used to store small amounts of non-volatile data in electronic systems. Typical data includes configuration settings, calibration values, identification numbers, system parameters, and user preferences. It is widely used in industrial control systems, consumer electronics, communication modules, instrumentation equipment, IoT devices, and embedded microcontroller applications where reliable data retention is required.
Q3: Does the M24C04-WMN6TP have alternative manufacturer and part numbers?
A: Direct drop-in replacements are available from other EEPROM manufacturers, since the M24C04-WMN6TP is a standard 4 Kbit I²C serial EEPROM. Similar compatible devices can be found from companies such as Microchip Technology, onsemi, Renesas Electronics, and ROHM Semiconductor, including parts like Microchip 24LC04B-I/SN, onsemi CAT24C04WI-GT3, and Renesas R1EX24004ASA00A. Any alternative must be carefully evaluated for supply voltage range, package type, I²C timing characteristics, memory organization, and pin compatibility to ensure proper system integration.
Q4: Is technical support available for the M24C04-WMN6TP?
A: Yes. Technical support is available through STMicroelectronics documentation, including datasheets and application notes. In addition, authorized distributors such as Nantian Electronics can provide datasheets, pin diagrams, stock information, pricing, and assistance with selection or substitution for design and procurement needs.
