Boasting of being the world's first USB 2.0 device controller, the NET2290 chip is said to rate high in design flexibility and in delivering system performance. With read/write cycle times of less than 15 ns--or over 1-Gb/s burst data rates--the Universal Serial Bus (USB) 2.0 chip is designed to minimize local CPU processing and software overhead while still achieving the maximum USB bandwidth. Targeted for CPU-based peripherals, the controller integrates on-chip an analog transceiver for USB 2.0, a direct interface to most 16/32-bit CPUs, seven endpoints, 8 KB of FIFO memory, a high-performance Serial Interface Engine (SIE), and highly integrated configuration logic. The NET2290's built-in dual-channel DMA interface and its automatic assignment of multiple-buffered FIFO are said to assure continuous high-speed USB performance.
The chip comes with a complete development kit, the NET2290PCI-RDK, whose PCI board allows engineers to easily emulate a USB 2.0 device without investing in software development tools or in-circuit emulators. And software developers can start their project in parallel with hardware designers to get a jump on time-to-market. The NET2290 chip comes in a 128-pin TQFP costing $15 each in initial volume quantities.
