Function Description
The HF88M02 is a command interfaced 256K x 8 bit Mask ROM. It features command mode interface
with external CPU or MCU. In other words, it uses only 8-bit data bus and a few additional control pins
to load addresses and provide the ROM access as well as expansion I/O ports capability. This design not
only reduces pin count required to access data in ROM dramatically but also allows for systems
expansion to higher capacity memories while using the existing board design. The application areas
include voice, graphic, data storage in consumer product.
