Overview

The ATMEGA16A-PU is an 8-bit AVR RISC-based microcontroller featuring 16KB of ISP flash memory, 1KB of SRAM, and 512 bytes of EEPROM. Housed in a 40-pin PDIP package, it provides 32 general-purpose I/O lines and an on-chip JTAG interface for programming and debugging. It operates at speeds up to 16MHz and includes a 2-cycle multiplier and six versatile sleep modes for power management.

Why Choose This Part

The through-hole 40-DIP package allows for easy prototyping without the need for specialized soldering equipment or adapter boards. It features a robust peripheral set including a 2-cycle hardware multiplier and a calibrated internal RC oscillator for simplified hardware design. High integration of JTAG and on-chip debug support streamlines the development and troubleshooting process.

Applications

Educational Development
The through-hole PDIP package makes it ideal for teaching embedded systems and assembly programming on breadboards.
Industrial Control Systems
Used for monitoring sensors and controlling actuators via its 32 I/O pins and integrated PWM channels.
Legacy System Maintenance
Serves as a drop-in replacement or update for older ATmega16 designs requiring long-term availability.
Home Automation Nodes
Handles simple logic for lighting, security sensors, and HVAC control using UART and I2C connectivity.

Getting Started

Developers can use the Microchip Studio (formerly Atmel Studio) IDE along with an AVR ISP mkII or JTAGICE programmer. For hardware development, the part fits directly into standard breadboards or 40-pin IC sockets. Programming can also be performed via the JTAG interface or using the In-System Programming (ISP) header.
