Microchip ATmega168PA-AU SMD IC

The ATmega168PA is a low power, CMOS 8-bit microcontroller based on the AVR,®, enhanced RISC architecture. By executing instructions in a single clock cycle, the devices achieve CPU, throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system, designer to optimize power consumption versus processing speed., The high-performance Microchip Pico Power,® 8-bit AVR,® RISC-based 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, a byte-oriented Two-Wire serial interface, SPI serial port, 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts., By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
