Overview

The M95040-WMN6TP is a 4Kbit non-volatile EEPROM organized as 512 x 8 bits, designed for reliable data storage in embedded systems. It operates over a wide voltage range of 2.5V to 5.5V and utilizes a high-speed SPI bus interface capable of clock frequencies up to 20 MHz. This component is optimized for low-power applications, drawing as little as 3uA in standby mode.

Why Choose This Part

This EEPROM offers a high-speed 20 MHz SPI clock for rapid data access and a versatile supply range suitable for both 3.3V and 5V logic systems. Its low 5mA maximum operating current and 3uA standby current make it ideal for battery-powered designs requiring efficient power management.

Applications

Microcontroller Boot Configuration
Storing setup parameters, trim values, and bootloader configuration data that must persist across power cycles.
Calibration Data Storage
Holding sensor calibration offsets and scaling factors in industrial instrumentation.
User Preference Logging
Saving small amounts of user-defined settings or state information in consumer electronics.
Event Counters
Maintaining error logs or usage counters that require byte-level alterability and high endurance.

Getting Started

Interface the M95040-WMN6TP to any MCU with an SPI peripheral using the standard MOSI, MISO, SCK, and CS pins. Ensure the Write Protect (WP) and Hold (HOLD) pins are tied high if not used to avoid unintended write-inhibition or communication pauses. Software implementation requires standard SPI byte-write and page-write commands as defined in the STMicroelectronics datasheet.
