概要

Description

The M27C256B-10F1 is a 256 Kbit (32KB) EPROM (Erasable Programmable Read-Only Memory) chip manufactured by STMicroelectronics. It is designed for applications requiring non-volatile memory storage, such as firmware and microcontroller programming. The "10" in its designation indicates a maximum access time of 100 nanoseconds, making it suitable for high-speed applications.
This EPROM features an 8-bit data bus, allowing it to read and write data in bytes. It operates with a supply voltage of 5V, with an additional 12.5V for programming. The chip can be erased using UV light, exposing the window on the top of the package, and can be programmed about 1,000 times.
The M27C256B-10F1 is commonly used in embedded systems, consumer electronics, and various industrial applications, where the need for reliable and reusable memory is essential. Its durability and capacity make it a popular choice among designers looking for efficient memory solutions.
