Overview
The M27C1001-70F1 is a 1 Mbit EPROM (Erasable Programmable Read-Only Memory) produced by STMicroelectronics. This device is available in two main types: UV (ultra violet erase) and OTP (one time programmable). It is designed to meet the needs of microprocessor systems that require large program storage, organized as 131,072 words of 8 bits each.
The M27C1001-70F1 is suitable for applications where high storage capacity and reliable data retention are essential. The device can be programmed using a standard EPROM programmer and can be erased using ultraviolet light for the UV version.
