ATTINY24A-SSU Introduction

Looking for a microcontroller that is both strong and affordable? Consider the ATTINY24A-SSU instead! This miniature computer on an integrated circuit was created and manufactured by Atmel Corporation, which is now a division of Microchip Technology Inc. It belongs to the renowned AVR microcontroller family, which is renowned for its superior performance, low power consumption, and broad functionality.

The ATTINY24A-SSU is an 8-bit microcontroller that first became available in 2011 as an upgrade to the ATTINY24. It makes use of the effective AVR RISC architecture. It is perfect for low-power applications that call for a compact design and a reasonable price because of its small form factor and low power consumption.

ATTINY24A-SSU Description

The ATtiny24A/44A/84A lets you experience the power of low-power CMOS 8-bit microcontrollers. The upgraded RISC architecture of the AVR, on which these microcontrollers are based, allows them to process powerful instructions in a single clock cycle and attain throughputs that are nearly 1 MIPS per MHz. With this special function, the system designer can balance the amount of power used and the speed of processing to get the best performance.

The AVR core has both a full set of instructions and 32 general-purpose working registers. In contrast to other microcontrollers, all 32 registers on this one are directly connected to the Arithmetic Logic Unit (ALU). This means that two different registers can be accessed at the same time during a single clock cycle. The ATtiny24A/44A/84A’s design makes it faster and more code-efficient than conventional CISC microcontrollers, providing you with a strong and dependable answer for your project’s requirements.

ATTINY24A-SSU Features

An 8-bit microcontroller called the ATTINY24A-SSU is based on the AVR RISC (Reduced Instruction Set Computing) architecture. Most of its instructions are run in a single cycle, which lets it have great performance while using little power.

Memory configuration: The ATTINY24A-SSU includes a total of 128 bytes of SRAM for data storage and 2 KB of flash memory for storing programs. It also has 128 bytes of EEPROM, which is a non-volatile memory that can be used to store configuration data and other important information.

14 I/O (input/output) pins make up the ATTINY24A-SSU in total, and each of these pins can be set up to function as either an input pin or an output pin. These pins can be used to control external devices and talk to sensors, among other things.

Two 8-bit timers and one 16-bit timer are included in the ATTINY24A-SSU, which can be utilized for timing and counting applications. These timers can be used to create interruptions, measure the length of events, and generate PWM (Pulse Width Modulation) signals.

Communication Protocols: The ATTINY24A-SSU works with a number of communication protocols, such as USART (Universal Synchronous/Asynchronous Receiver/Transmitter), I2C (Inter-Integrated Circuit), and SPI (Serial Peripheral Interface). Using these protocols, you can talk to other devices like sensors, displays, and other microcontrollers.


Industrial Applications: The ATTINY24A-SSU is suitable for a variety of industrial applications, including temperature detection, motor control, and process control. For applications that need great dependability at a low cost, its tiny form factor and low power consumption make it the perfect option.

Applications in consumer electronics: The ATTINY24A-SSU is also ideally suited for a variety of consumer electronics applications, including wearable technology, toys, and remote controls. For battery-powered devices that need a long battery life, its tiny size and low power consumption make it the perfect option.

Gadgets for the Internet of Things (IoT): Because of its support for SPI and I2C, the ATTINY24A-SSU is ideally suited for use in IoT devices like smart home gadgets, environmental sensors, and smart meters. Its low power consumption also makes it a great option for IoT devices that run on batteries.

Robotics and automation: The ATTINY24A-SSU has a number of applications in robotics and automation, such as motor control, sensor interfaces, and control systems. Its support for communication protocols including USART and I2C make it a flexible option for directing and interacting with other components in a robotic or automation system.


  • Low Power Consumption: The ATTINY24A-SSU is developed for low power applications and, when compared to other microcontrollers, has a very low power consumption, making it perfect for battery-powered devices.
  • Diverse Communication Protocols: The ATTINY24A-SSU supports a number of communication standards, including SPI, I2C, and USART, which makes it simple to connect to other devices.
  • Compact SSU (Shrink Small Outline Packaging) form factor: The ATTINY24A-SSU is a diminutive microcontroller that is perfect for applications that call for a small footprint.
  • Cost-Effective: The ATTINY24A-SSU is a reasonably priced microcontroller with good performance-price ratio, making it a popular option for a variety of applications.


  • Restricted Memory: The ATTINY24A-SSU has a meager amount of EEPROM, SRAM, and flash memory, which might not be enough for all applications.
  • Low Processing Power: The ATTINY24A-SSU is an 8-bit microcontroller, making it potentially unsuitable for applications requiring significant processing power.
  • Low I/O Pin Count: The ATTINY24A-SSU only has a small number of I/O pins, which might not be enough for some applications.

Comparing several microcontrollers

The ATTINY24A-SSU is a solid option when compared to other microcontrollers for applications that call for low power consumption, a tiny form factor, and flexible communication protocols. It might not work well for applications that need a lot of I/O pins, a lot of memory, or significant computing power, though. The ATTINY24A-SSU is a lower-end microcontroller in the AVR family than some of the higher-end variants, including the ATmega series, and has less memory. Yet, it is more economical and uses less power than these types.


In short, the ATTINY24A-SSU is a powerful microcontroller with many benefits, such as low power consumption, a small size, and a wide range of communication protocols. Even though it has some limitations, it is still a popular choice for a wide range of applications, such as industrial, consumer electronics, IoT devices, robotics, and automation, because it offers a great balance between price and performance.
