(1)

The TUSB3210 has 8K

× 8 RAM for development.

(2)

This is the buffer space for USB packet transactions.

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

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. In

addition, the vast amounts of application code available in the general market also can be used (this may

or may not require some code modification due to hardware variations).
