1 / 16 page 1/16 September 2000 M27C801 8 Mbit (1Mb x 8) UV EPROM and OTP EPROM s 5V ± 10% SUPPLY VOLTAGE in READ OPERATION s ACCESS TIME: 45ns s LOW POWER CONSUMPTION: – Active Current 35mA at 5MHz – Standby Current 100µA s PROGRAMMING VOLTAGE: 12.75V ± 0.25V s PROGRAMMING TIME: 50µs/word s ELECTRONIC SIGNATURE – Manufacturer Code: 20h – Device Code: 42h DESCRIPTION The M27C801 is an 8 Mbit EPROM offered in the two ranges UV (ultra violet erase) and OTP (one time programmable). It is ideally suited for applica- tions where fast turn-around and pattern experi- mentation are important requirements and is organized as 1,048,576 by 8 bits. The FDIP32W (window ceramic frit-seal package) has transparent lid which allows 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 M27C801 is offered in PDIP32, PLCC32 and TSOP32 (8 x 20 mm) packages. 1 32 FDIP32W (F) PLCC32 (K) TSOP32 (N) 8 x 20 mm 32 1 PDIP32 (B) Figure 1.
