ATMEGA168P-20AU

The ATmega48P/V/88P/V/168P/V is a low power, CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. This specific model, the ATMEGA168P-20AU, offers 16KB of in-system self-programmable Flash program memory and 1KB of internal SRAM. It operates at a speed of 20MHz and supports a voltage range of 2.7V to 5.5V.

Key peripherals include two 8-bit Timer/Counters, one 16-bit Timer/Counter, a Real Time Counter, six PWM channels, and an 8-channel 10-bit ADC. Connectivity options include I²C, SPI, and UART/USART interfaces. The microcontroller also features a programmable watchdog timer and an on-chip analog comparator.

Designed for high performance and low power consumption, this device is suitable for a wide range of embedded applications. It operates within a temperature range of -40°C to 85°C and is available in a compact 32-TQFP package, suitable for surface mount applications.

Features like Power-on Reset, Programmable Brown-out Detection, and multiple sleep modes contribute to its robust design. The advanced RISC architecture allows for most instructions to execute in a single clock cycle, achieving high throughput.
