(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
programmed via an inter-IC (I
2
C) 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. 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).
