Product Introduction

Overview

The M95320-DWDW4TP/K is a 32-Kbit serial SPI bus Electrically Erasable Programmable Memory (EEPROM) produced by STMicroelectronics. This device is designed for high-reliability applications, particularly in the automotive and industrial sectors. It features a compact 8-TSSOP package and supports a wide range of operating temperatures, making it suitable for demanding environments. The EEPROM is accessed through the Serial Peripheral Interface (SPI) bus, allowing for efficient data transfer and storage.
