DESCRIPTION

The MR53V8052J 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 MR53V8052J operates asynchronously,

external clocks are not required, making this device easy-to-use. The MR53V8052J 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.
