HY23V28101
Description
8MX16BIT
CMOS MASK ROM
The HY23V28101 high performance read only memory is organized either as 8,388,608 x16 bit (word mode)
and has an access time of 100/120ns. It needs no external control clock to assure simple operation, because of
its asynchronous operation. It is designed to be suitable for use in program memory of game machine, data
memory and entertainments. The HY23V28101 is packaged in a 44SOP provides polarity programmable CE
and OE buffer as user option mode.
