AVR16DD28-I/SO

Overview

The AVR16DD28-I/SO is an 8-bit microcontroller from the AVR DD family, utilizing the AVR CPU with a hardware multiplier. It features 16 KB of in-system self-programmable Flash memory, 2 KB of SRAM, and 256 bytes of EEPROM. The device operates at clock speeds up to 24 MHz within a supply voltage range of 1.8V to 5.5V. It includes a 12-bit ADC with 19 channels, a 10-bit DAC, two USARTs, SPI, TWI/I2C interfaces, and Multi-Voltage I/O (MVIO) on Port C. The component is housed in a 28-pin SOIC package and supports industrial temperature ranges.

Feature Summary

Multi-Voltage I/O (MVIO) capability enables direct bidirectional communication between different power domains without external level shifters.
Configurable Custom Logic (CCL) provides four programmable Look-up Tables for custom digital logic implementation.
Event System allows for CPU-independent inter-peripheral signaling to reduce system latency.
Single-pin Unified Program and Debug Interface (UPDI) simplifies programming and debugging connections.

Applications

Industrial control systems requiring real-time processing
Smart home appliances with multiple power domains
Internet of Things (IoT) devices
Automotive embedded applications

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature rating. Ensure compatibility with existing design constraints regarding the 28-pin SOIC footprint. Confirm that the selected variant meets the required operational specifications for your application environment.

Selection Notes

Select this component when vertical migration within the AVR DD family is desired without code modification. Consider the MVIO feature if interfacing with peripherals operating at different voltage levels. Evaluate the peripheral count, specifically the number of ADC channels and timers, against project requirements before finalizing the selection.

Part Context

This part belongs to the AVR DD family of microcontrollers, which are designed for low-power and high-performance applications. The family offers pin-to-pin compatibility across various pin counts and memory sizes, facilitating easy upgrades or downgrades in product designs without hardware redesign.
