ATMEGA1284 is a kind of 8-bit Microchip AVR RISC-based high performance Microcontroller, combining 128KB ISP flash memory with read-while-write capabilities. The Microcontroller is one of its primary functions. It features Advanced RISC Architecture, High Endurance Non-volatile Memory Segments, 20 MIPS/DMIPS CPU speed, 4096 Bytes Data Eeprom/HEF, and one comparator.
This post is mainly to introduce the ATMEGA1284 pinout and ATMEGA1284 circuit diagram for your demands.
ATMEGA1284 has 40 pins, and each pin has individual usage to make the whole chip achieve its function.
The ATMEGA1284 pinout can be found in the picture below:
also the pin configurations for ATMEGA1284 are labeled already.
ATMEGA1284 circuit schematic
A circuit schematic can better help us to understand circuits and components used, and it's a reference to make the actual circuit work.
Below is a fully labeled ATMEGA1284 schematic diagram for reference.
Referring to ATMEGA1284 Features, the first scene we can think is it works as Microcontroller.
Except that one, there still have some other features we may need to know, which can help us to make use of it well, such as utilize in Special Microcontroller Features: Power-on Reset and Programmable Brown-out Detection, Internal Calibrated RC Oscillator, External and Internal Interrupt Sources, Six Sleep Modes: Idle, ADC Noise Reduction, Power-save, Power-down, Standby, and Extended Standby.
