MCU USB设备

1 AMD am186
1.1 am186cu
am186 runs 8086 instruction set. am186cc means communications controller, am186cu means communications USB.
Only the USB data endpoints can be used with the SmartDMA controller. Endpoint A must be configured for OUT data on SmartDMA Channel 2 (receive), while Endpoint B must be configured for IN data on the SmartDMA Channel 2 (transmit). Endpoint C must be configured for OUT on Channel 3 (receive), and Endpoint D must be IN on Channel 3 (transmit). Depending on the application, the appropriate endpoint should be chosen.

1.2 am186ESLV
am186ESLV means 16-Bit Embedded SRAM Low-Voltage.

2 Cypress EZ USB
