ATTINY841-MMH

Overview

The ATTINY841-MMH is an 8-bit AVR microcontroller featuring 8K bytes of in-system programmable Flash, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at up to 16 MHz with a throughput of 16 MIPS. The device includes one 8-bit and two 16-bit Timer/Counters, a 10-bit ADC with 17 channels, two USARTs, SPI, and I2C interfaces. It supports a supply voltage range of 1.7V to 5.5V and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

Advanced RISC architecture executing most instructions in a single clock cycle for high efficiency.
Integrated non-volatile memory with high endurance for program and data storage.
Comprehensive peripheral set including multiple timers, analog-to-digital converter, and serial communication interfaces.
Multiple low-power operating modes to optimize energy consumption.

Applications

Battery-powered sensor nodes
Industrial control systems
Smart home appliances

Procurement Notes

Verify the specific ordering code suffix against official Microchip documentation to confirm package type and tape/reel configuration. Ensure the selected variant matches the required speed grade and temperature range for the target application environment.

Selection Notes

Select this component when 8KB of Flash memory and advanced timer configurations are required. Consider the VQFN package dimensions for PCB layout constraints. Evaluate power consumption requirements across different sleep modes if battery operation is critical.

Part Context

This part belongs to the ATtiny441/841 family of 8-bit AVR microcontrollers. It shares architectural similarities with other devices in the series but offers specific memory capacities and pin configurations tailored for compact embedded applications requiring robust peripheral integration.
