The M27256-2FI is a UV erasable programmable read-only memory (UV EPROM) chip produced by STMicroelectronics. It has a capacity of 256 Kbit, or 32 Kilobytes, and is organized as 8 bits per byte.
This chip can be programmed using ultraviolet (UV) light and can be erased using the same method. It is often used in applications where reprogramming of the memory is required, such as in the development of software or firmware.
The M27256-2FI is a NMOS (negative-channel metal-oxide-semiconductor) device, which means it uses a negatively charged channel to control the flow of electrons through the device.
It is suitable for use in a wide range of applications, including industrial, automotive, and consumer electronics.
