HY23C08200
Description
512K X 16/1M X 8 BIT
CMOS MASK ROM
The HY23C08200 high performance read only memory is organized either as 1,048,576 x 8 bit (byte mode)
or as 524,288 x 16 bit(word mode) followed by BHE mode select. The low power feature allows the battery
operation.
The large size of 8M bit memory density is ideal for character generator, data or program
memory in micro-processor application. The HY23C08200 is packaged 42pin DIP or 44 pin SOP.
