The main difference between uPSD34xx and uPSD33xx are, uPSD34xx family support full speed USB 2.0 runs with PLL. In addition, uPSD34xx family have 16-bit wide Prefetch Queue thus higher performance compare to the 8-bit wide PFQ on the uPSD33xx family processors. uPSD34xx family processors should be available by Feb. 04.
