Atmega168-PU 8-bit IC Microcontroller

Description
The high-performance, low-power Microchip AVR® RISC-based CMOS 8-bit microcontroller combines 16 KB ISP flash memory with read-while-write capabilities, 512B EEPROM, 1 KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, byte-oriented Two-Wire serial interface, SPI serial port, 6-channel/10-bit A/D converter (8-channel in TQFP and QFN packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
