GENERAL DESCRIPTION
The WT65F5 is highly integrated Micro controller with Universal Serial Bus (USB)
interface. It contains an 8051 based CPU core, 64K bytes Flash memory, 2304
bytes (2K+256 bytes) RAM, USB transceiver, Serial bus Interface Engine (SIE),
System Interface Logic (SIL) and transmit / receive FIFOs. The USB function
supports low/full-speed data rate (1.5M & 12M bps), suspend / resume mode,
control / interrupt/ bulk transfer and is fully compliant with the USB specification
version 1.1.
