说明

The TUSB3210 is a USB-based controller targeted as a general-purpose MCU with GPIO. The TUSB3210 has 8K × 8 RAM space for application development. In addition, the programmability of the TUSB3210 makes it flexible enough to use for various other general USB I/O applications. Unique vendor identification and product identification (VID/PID) can be selected without the use of an external EEPROM. Using a 12-MHz crystal, the onboard oscillator generates the internal system clocks. The device can be programmed via an inter-IC (I²C) serial interface at power on from an EEPROM, or optionally, the application firmware can be downloaded from a host PC via USB. The popular 8052-based microprocessor allows several third-party standard tools to be used for application development.
