The AT90USB1287-AU is a 8-bit high-performance low-power AVR RISC-based Microcontroller combines 128kB ISP flash memory with read-while-write capabilities, 4kB EEPROM, 8kB SRAM, 48 general purpose I/O lines, 32 general purpose working registers, real time counter, four flexible timer/counters with compare modes and PWM, USART, byte oriented 2-wire serial interface, USB 2.0 low-speed and full-speed On-The-Go (OTG) host/device, an 8-channel 10-bit A/D converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, SPI serial port, JTAG (IEEE 1149.1 compliant) interface for on-chip debugging and six software selectable power saving modes. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processor speed.
• Advanced RISC architecture — On-chip 2-cycle multiplier
• Non-volatile program and data memories
• JTAG (IEEE 1149.1 compliant) interface — Extensive on-chip debug support
• USB 2.0 full-speed/low-speed device and on-the-go module
• USB full-speed/low speed device module with interrupt on transfer completion
• USB OTG reduced host
• Peripheral features — Real time counter with separate oscillator
• Power-on reset (POR) and programmable brown-out detection
• Internal calibrated oscillator
• External and internal interrupt sources
• Six sleep modes — Idle, ADC noise reduction, power-save, power-down, standby and extended standby
