1 / 15 page 1/15 PRELIMINARY DATA September 1998 This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. M27C320 32 Mbit (4Mb x8 or 2Mb x16) OTP EPROM s 5V ± 10% SUPPLY VOLTAGE in READ OPERATION s FAST ACCESS TIME: 80ns s BYTE-WIDE or WORD-WIDE CONFIGURABLE s 32 Mbit MASK ROM REPLACEMENT s LOW POWER CONSUMPTION – Active Current 70mA at 8MHz – Stand-by Current 100mA s PROGRAMMING VOLTAGE: 12V ± 0.25V s PROGRAMMING TIME: 100 µs/byte (typical)(PRESTO III Algorithm) s ELECTRONIC SIGNATURE: – Manufacturer Code 0020h – Device Code: 0032h DESCRIPTION The M27C320 is a 32 Mbit EPROM offered in the OTP range (one time programmable). It is ideally suited for microprocessor systems requiring large data or program storage. It is organised as either 4 MWords of 8 bit or 2 MWords of 16 bit. The pin- out is compatible with the 32 Mbit Mask ROM. The M27C320 is offered in TSOP48 (12 x 20mm) and SO44 packages. 44 1 SO44 (M) TSOP48 (N) 12 x 20 mm Figure 1.
