What Is the ATmega16? 40-Pin AVR MCU: Specs and Uses
The ATmega16 is a classic 40-pin 8-bit AVR microcontroller. It offers 16 KB flash, 1 KB SRAM, 32 GPIO and an 8-channel 10-bit ADC (16 MHz, PDIP-40). It is common in teaching and industrial projects; it is largely compatible with the ATmega32 (half flash). It is the AVR-side counterpart of the PIC16F877A.
The ATmega16 is a classic 40-pin 8-bit AVR microcontroller. With plenty of I/O and rich peripherals, it was long a standard in teaching and industrial projects. For the concept, see what is a microcontroller (MCU).
What is the ATmega16 used for?
General embedded control, LCD/keypad, sensor reading (ADC), motor driving and serial communication. With a 40-pin DIP and 32 GPIO, it is the AVR-side counterpart of the PIC16F877A. It is largely compatible with the ATmega32 (less flash).
