Microchip (ATMEGA168P-20AU) 8 Bit MCU, 20 MHz, 16 KB, 32 Pins, TQFP

8 Bit MCU, AVR ATmega Family ATmega16X Series Microcontrollers, 20 MHz, 16 KB, 32 Pins, TQFP Product Overview The ATMEGA168P-20AU is a 8-bit high-performance picoPower AVR RISC-based Microcontroller combines 16kB ISP flash memory with read-while-write capabilities, 512B EEPROM, 1kB 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 2-wire serial interface, SPI serial port, 6-channel 10-bit A/D converter (8-channel in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator 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. The AVR core combines a rich instruction set with 32 general purpose working registers.
