M95160-A125

The M95160-A125 is a serial 16 Kbit EEPROM from STMicroelectronics, designed for low-power, high-reliability data storage applications. It operates with a supply voltage range of 1.8 V to 5.5 V, making it suitable for both battery-powered and standard industrial systems. The device supports two communication protocols—SPI-compatible serial interface (Mode 0 and Mode 3) and a 4-wire interface with chip select, allowing flexible integration into various embedded systems. This memory features a 16 Kbit (2048 x 8) array organized in 256 pages of 8 bytes each, enabling efficient read and write operations. Write protection is implemented via hardware pin control and software-based sector locking, ensuring data integrity and preventing accidental overwrites. The memory supports up to 1 million erase/write cycles and retains data for up to 200 years at 25°C, offering long-term reliability in demanding environments. The M95160-A125 includes built-in write protection mechanisms such as the Write Enable Latch (WEL), which must be set before any write operation, and an internal write cycle timer that ensures proper programming timing without external intervention. Its compact 8-pin SO8 package and low active current consumption (typically 5 mA at 5 V) make it ideal for space-constrained and power-sensitive applications. Common applications include consumer electronics, automotive systems, industrial controls, and smart meters, where non-volatile memory is required to store configuration settings, calibration data, or user preferences. It is particularly well-suited for use in devices operating under varying temperature conditions due to its wide operating temperature range of -40°C to +85°C. The device also includes an automatic address increment feature for burst reads and writes, enhancing performance during bulk data transfers. Additionally, it offers robust ESD protection on all pins, improving resilience against electrostatic discharge during handling and operation. With its combination of low power, high endurance, and reliable performance, the M95160-A125 provides an efficient solution for embedded systems requiring persistent, secure, and easily accessible memory storage.
