Overview
The STMicroelectronics M27C64A-20F6 is a 64Kbit EPROM (Erasable Programmable Read-Only Memory) device. This component is available in two main types: UV (ultra violet erase) and OTP (one time programmable). Although it is now an obsolete (EOL) component, it was widely used in various applications requiring non-volatile memory. The M27C64A-20F6 is configured as 8K x 8 bits, making it suitable for storing small to medium-sized programs or data.
