Overview
The M27C1001-15C1 is a 1 Mbit EPROM (Erasable Programmable Read-Only Memory) produced by STMicroelectronics. It is available in two main types: UV (ultra violet erase) and OTP (one time programmable). This device is particularly suited for microprocessor systems that require large program storage and is organized as 131,072 words of 8 bits each.
The M27C1001-15C1 is offered in various packages, including FDIP32W (window ceramic frit-seal package), PDIP32, PLCC32, and TSOP32. The FDIP32W package features a transparent lid, allowing the chip to be exposed to ultraviolet light for erasure. For environmental compliance, ECOPACK® packages are also available, which are lead-free and meet JEDEC standards.
