M95320-RMN6TP

M95320-RMN6TP

STMicroelectronics
EEPROM Memory IC 32Kbit SPI 20 MHz 8-SOIC
Active11,514 in stock

Overview

The M95320-RMN6TP is a 32Kbit serial SPI EEPROM organized as 4096 x 8 bits. It operates across a wide supply voltage range of 1.8V to 5.5V and supports high-speed clock frequencies up to 20 MHz. This non-volatile memory is designed for reliable data storage in space-constrained designs using the industry-standard 8-SOIC package.

Why Choose This Part

This device offers a low standby current of 1 uA and a wide operating voltage range, making it suitable for battery-powered applications. The 20 MHz SPI interface ensures fast read and write access, while the 4K x 8 organization provides a compact memory footprint for many microcontroller-based projects.

Applications

Configuration Storage
Storing calibration data, device settings, and user preferences in embedded systems.
Firmware Metadata
Housing bootloader parameters, version strings, and lookup tables that require infrequent updates.
Event Logging
Recording error codes, timestamps, and sensor event history for diagnostic purposes.

Getting Started

To interface with the M95320-RMN6TP, configure your microcontroller's SPI peripheral to Mode 0 or Mode 3. Ensure the Write Protect and Hold pins are tied to VCC if not actively used. You can verify communication by reading the Status Register or performing a simple write-then-read sequence to a known memory address.
