Preliminary
2,097,152-Word X 16-Bit or 4,194,304-Word X 8-Bit
8Word X 16-Bit or 16Word X 8-Bit/Page Mode MASK ROM
DESCRIPTION
The MR533252J is a 32Mbit Read-Only Memory whose configuration can be electrically switched
between 2,097,152 word x 16bit and 4,194,304 word x 8bit. The MR533252J operates asynchronously,
external clocks are not required, making this device easy-to-use. The MR533252J is suitable as largecapacity fixed memory for microcomputers and data terminals. It is manufactured using a CMOS
silicon gate technology and is offered in 44-pin SOP or 44-pin TSOP packages.
