1MX16/2MX8 BIT
CMOS MASK ROM
HY23V16202
Description
The HY23V16202 high performance read only memory is organized either as 2,097,152 x 8 bit (byte mode) or
as 1,048,576 x 16 bit(word mode) followed by BHE mode select. The low power feature allows the battery
operation.
The large size of 16M bit memory density is ideal for character generator, data or program
memory in micro-processor application. The HY23V16202 is packaged 42pin DIP , 44 pin SOP, 44 pin
TSOP-II or 48 pin TSOP-I.
