The M93C86-WMN6TP is a 256-bit Serial EEPROM manufactured by STMicroelectronics. It has an 8-pin SOIC package and uses a serial peripheral interface to read and write data. The 8 pins are Vcc, Gnd, clock, chip select, data input, data output, write protect, and output enable. The part is a nonvolatile memory, meaning the data stored in the chip will remain even when power is removed. The M93C86-WMN6TP is suitable for use in a variety of applications, including automotive systems, remote control systems, industrial controllers, and more.
