AT90USB162-16AU Datasheet PDF - Microchip

●The AT90USB162-16AU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 16kb ISP flash memory with read-while-write capabilities, 512B EEPROM, 22 general purpose I/O lines, 32 general purpose working registers, two flexible timer/counters with compare modes and PWM, USART, programmable watchdog timer with internal oscillator, SPI serial port, debugWIRE interface for on-chip debugging and programming and five software selectable power saving modes. The device operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
