Agere Triple Performance of USB 2.0 Device Microcontrollers

Agere Systems introduced a Universal Serial Bus (USB) 2.0 system-on-a-chip with an on-board microprocessor that processes data more than three times faster than widely deployed 8051-based USB 2.0 device controllers.



The new chip integrates an ARM7TDMS microprocessor and processes 40 million instructions per second (MIPS), compared to 12 Mbps for competing designs.



USB 2.0 PC-based applications that might benefit from the added performance include cameras, MP3 players and scanners. One example could be boosting the speed at which a scanner performs image processing.



The chip supports both high-speed USB 2.0 (480 Mbps) and full-speed (12 Mbps) data transfers.
