1 / 16 page 1/16 September 1998 M27V800 8 Mbit (1Mb x8 or 512Kb x16) Low Voltage UV EPROM and OTP EPROM s LOW VOLTAGE READ OPERATION: 3V to 3.6V s FAST ACCESS TIME: 100ns s BYTE-WIDE or WORD-WIDE CONFIGURABLE s 8 Mbit MASK ROM REPLACEMENT s LOW POWER CONSUMPTION – Active Current 30mA at 8MHz – Standby Current 20 µA s PROGRAMMING VOLTAGE: 12.5V ± 0.25V s PROGRAMMING TIME: 100 µs/byte (typical) s ELECTRONIC SIGNATURE – Manufacturer Code: 0020h – Device Code: 00B2h DESCRIPTION The M27V800 is a low voltage 8 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 data or program storage. It is organised as either 1 Mbit words of 8 bit or 512 Kbit words of 16 bit. The pin- out is compatible with a 8 Mbit Mask ROM. 1 42 1 42 44 1 FDIP42W (F) PDIP42 (B) SO44 (M) PLCC44 (K) Figure 1.
