1 / 16 page 1/16 April 1999 M27C2001 2 Mbit (256Kb x 8) UV EPROM and OTP EPROM s 5V ± 10% SUPPLY VOLTAGE in READ OPERATION s FAST ACCESS TIME: 55ns s LOW POWER CONSUMPTION: – Active Current 30mA at 5MHz – Standby Current 100 µA s PROGRAMMING VOLTAGE: 12.75V ± 0.25V s PROGRAMMING TIME: 100 µs/byte (typical) s ELECTRONIC SIGNATURE – Manufacturer Code: 20h – Device Code: 61h DESCRIPTION The M27C2001 is a high speed 2 Mbit EPROM of- fered 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. Figure 1.
