MG64F225中文资料USB 6502 MCU数据手册Megawin规格书

描述 Description

The MG64F237 is a 65C02 MCU with an USB 2.0 low-speed interface.  A PS/2 connection can be established on USB DP & DM pins by user firmware.  It will be very suitable for low-cost keyboard and products like hand-held game, data bank, and I-toy, which need to download/upload data from the PC host.
