DESCRIPTION

The MR27V1602E is a 16 Mbit electrically Programmable Read-Only Memory that can be electrically switched between 1,048,576-word × 16-bit and 2,097,152-word × 8-bit configurations. This device operates on a single +3.3V power supply, and all inputs and outputs are TTL compatible. Because of its asynchronous operation, it requires no external clocks, making this device easy-to-use.

The MR27V1602E is suitable as large-capacity fixed memory for microcomputers and data terminals. It is manufactured using a CMOS double silicon gate technology and is offered in 44-pin SOP, 44-pin TSOP(II) or 48-pin TSOP(I) packages.

APPLICATION
