ATTINY441-MMH

Overview

The ATTINY441-MMH is an 8-bit AVR microcontroller featuring 4K bytes of in-system programmable Flash, 256 bytes of EEPROM, and 256 bytes of SRAM. It operates at speeds 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 delivering up to 16 MIPS throughput at 16 MHz
• Integrated analog peripherals including a 10-bit ADC with differential inputs and two on-chip analog comparators
• Dual full-duplex USARTs with start frame detection for versatile serial communication
• Four software-selectable power-saving modes including Idle, ADC Noise Reduction, Standby, and Power-down

Applications

• Battery-powered embedded systems requiring low active and standby current consumption
• Industrial control applications utilizing multiple timers and high-current drive capability
• Sensor interface modules leveraging the 10-bit ADC and programmable gain amplifiers
• Communication nodes employing dual USARTs or Master/Slave SPI and Slave I2C interfaces

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm package type and speed grade. Ensure that the selected variant matches the required operating voltage and temperature range specifications for your application environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require high performance per milliwatt due to its single-cycle execution architecture. Consider the 14-pin SOIC package availability if board space is constrained. Evaluate the need for dual USARTs and extensive timer resources against simpler alternatives if peripheral requirements are minimal.
