ATMEGA168P-20ANR Description

Short technical summary and product information.

The ATMEGA168P-20ANR is an 8-bit AVR microcontroller from Microchip Technology based on the high-performance, low-power AVR enhanced RISC architecture. It features 16KB of in-system self-programmable Flash program memory, 1KB internal SRAM, and 512B EEPROM. The device operates at a maximum clock frequency of 20MHz, delivering up to 20 MIPS throughput.

 

Key peripherals include two 8-bit timer/counters, one 16-bit timer/counter with capture mode, six PWM channels, an 8-channel 10-bit ADC, and a programmable watchdog timer. Connectivity options include I²C, SPI, and UART/USART interfaces. The microcontroller also supports QTouch capacitive touch sensing.

 

The device is supplied in a 32-TQFP package (7x7mm) with surface mount mounting. It operates over a supply voltage range of 2.7V to 5.5V and a temperature range of -40°C to +105°C. The internal oscillator eliminates the need for external clock components in many applications.
