M27C2001 is a high speed 2 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for microprocessor systems requiring large pro- grams and is organised as 262,144 by 8 bits. The FDIP32W (window ceramic frit-seal package) and LCCC32W (leadless chip carrier package) have a transparent lids which allow the user to ex- pose the chip to ultraviolet light to erase the bit pat- tern. A new pattern can then be written to the device by following the programming procedure. For applications where the content is programmed only one time and erasure is not required, the M27C2001 is offered in PDIP32, PLCC32 and TSOP32 (8 x 20 mm) packages.
The M27C2001 is a high-speed 2 Mbit (256Kb x 8) EPROM available in both UV erasable and One-Time Programmable (OTP) versions. It is organized as 262,144 by 8 bits and operates with a single +5V supply voltage during read operations.
The device features two control functions: Chip Enable (E) for power control and Output Enable (G) to gate data to the output pins. It supports various packages including FDIP32W, LCCC32W, PDIP32, PLCC32, and TSOP322. Programming requires a Vpp voltage of 12.75V.
