AT90USB646 概述

USB Function Microcontroller.
64-Kbyte self-programming Flash Program Memory, 4-Kbyte SRAM, 2-Kbyte EEPROM, 8 Channel 10-bit A/D-converter. JTAG interface for on-chip-debug. Up to 16 MIPS throughput at 16 MHz. 2.7 - 5.5 Volt operation.

The AT90USB64/128 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By execut ing powerful inst ruct ions in a single clock cycle, the AT90USB64/128 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
