Preliminary
524,288-Word X 16-Bit or 1,048,576-Word X 8-Bit MASK ROM
DESCRIPTION
The MR53V8002J is a 8Mbit Read-Only Memory whose configuration can be electrically switched
between 524,288 word x 16bit and 1,048,576 word x 8bit. The MR53V8002J operates asynchronously,
external clocks are not required, making this device easy-to-use. The MR53V8002J is suitable as
large-capacity fixed memory for microcomputers and data terminals. It is manufactured using a CMOS
silicon gate technology and is offered in 42-pin DIP, 44-pin SOP or 44-pin TSOP packages.
