USB 2.0 Device Enables Multi-Speed Control

Designed for use with an external processor, the M66591GP USB 2.0 peripheral controller provides both high-speed (480 Mb/s) and full-speed (12 Mb/s) control, as well as bulk, and interrupt transfers. The device comes in an 80-pin, 10 mm x 10 mm LQFP with a 0.4 mm pitch and integrates a power management function and a 1.8V or 3.3V power-source interface. Other integrated features include a USB transceiver, multi-function high-speed bus interface, an independent eight-bit split bus (DMA interface), a multiplex-selectable, 16-bit CPU bus, and a 3.5 KB FIFO. Each endpoint is said to be optimized by transfer type, transfer direction, and FIFO memory size. The M66591GP is sampling now with volume production scheduled for the second quarter. Pricing is $12 each in sample quantities. For further information, contact MITSUBISHI ELECTRIC & ELECTRONICS USA INC., Sunnyvale, CA. (408) 774-3191.
