Overview

The Microchip ATTINY841-SSU is an 8-bit AVR microcontroller operating at up to 16MHz. It features 8KB of In-System Programmable Flash memory, 512 bytes of SRAM, and 512 bytes of EEPROM. This MCU offers a balance of performance and low power consumption for embedded applications requiring a compact footprint.

Why Choose This Part

Engineers choose the ATTINY841-SSU for its reliable 8-bit AVR core, offering robust performance up to 16MHz. Its integrated communication peripherals (I2C, SPI, UART) simplify connectivity in diverse embedded designs. The device's low-power modes and compact 14-SOIC package make it suitable for space-constrained, battery-sensitive applications.

Applications

Embedded Control Systems
Ideal for general-purpose embedded control tasks where a compact, low-power 8-bit MCU is sufficient, managing sensors, actuators, and basic logic.
Portable Battery-Powered Devices
Its low-power modes, including Idle, ADC Noise Reduction, Power-down, and Standby, make it suitable for devices that require extended battery life.
Sensor Interface and Data Acquisition
With 12 I/O pins, an on-chip analog comparator, and communication interfaces like I2C, SPI, and UART, it can effectively interface with various sensors and collect data.
Simple Human-Machine Interface (HMI)
Can be used in applications requiring basic user input and output, such as controlling LEDs, reading buttons, or driving small displays via serial communication.
Motor and Actuator Control
The integrated PWM peripheral allows for direct control of small motors, solenoids, or other actuators in simple control loops.

Getting Started

To get started with the ATTINY841-SSU, engineers typically use Microchip's MPLAB X IDE with an AVR programmer/debugger like the Atmel-ICE or Pickit 4. The device is compatible with the standard AVR toolchain, including avr-gcc. The Atmel Studio IDE (now integrated into MPLAB X) provides a comprehensive development environment for AVR microcontrollers.
