The Microchip Technology ATmega161-4PC is an 8-bit AVR RISC microcontroller featuring 8KB of FLASH program memory and 512 bytes of Data EEPROM. It operates at a maximum clock frequency of 4MHz and utilizes a CMOS technology. This component offers 35 general-purpose I/O lines, three 8-bit timers, and two UARTs for serial communication, alongside SPI connectivity. Integrated peripherals include an analog comparator, Power-on Reset (POR), Pulse Width Modulation (PWM), and a Watchdog Timer (WDT). With a 16-bit address bus width and an 8-bit external data bus, it supports up to three external interrupts. The ATmega161-4PC is housed in a 40-pin PDIP package, suitable for through-hole mounting, and operates within a temperature range of 0°C to 70°C with a supply voltage range of 3.0V to 5.5V. This microcontroller finds application in industrial automation, consumer electronics, and embedded control systems.
