Overview

The ATTINY24A-PU is an 8-bit AVR microchip in a 14-pin PDIP package, offering 2KB of flash and 12 I/O lines. It is designed for simple, low-power applications where a small through-hole footprint is required for prototyping or legacy system support. This microcontroller operates at speeds up to 20MHz and includes an integrated temperature sensor and internal calibrated oscillator.

Why Choose This Part

This MCU provides a balance of 12 I/O pins in a compact 14-DIP package, making it easier to integrate than 8-pin variants while remaining breadboard-friendly. It features 128 bytes of EEPROM for non-volatile parameter storage and supports debugWIRE for efficient on-chip debugging.

Applications

Battery-Powered Handheld Devices
Utilizes low-power modes and 0.21mA run current (at 1.8V/1MHz) to extend life in portable electronics.
Simple Sensor Nodes
The integrated temperature sensor and 10-bit ADC allow for compact environmental monitoring solutions.
GPIO Expansion
Serves as a dedicated peripheral controller or I/O expander communicating via the Universal Serial Interface (USI).

Getting Started

Developers can program the ATTINY24A-PU using the Microchip Studio (formerly Atmel Studio) IDE or the AVR-GCC toolchain. Hardware programming is typically performed via an AVRISP mkII or an MPLAB SNAP programmer connected to the SPI pins. For prototyping, the PDIP package can be directly inserted into standard breadboards or 14-pin DIP sockets.
