AVR16DD28T-I/STX

Overview

AVR16DD28T-I/STX is an 8-bit AVR microcontroller with 16 KB Flash, 2 KB SRAM, and 256 B EEPROM. It operates at up to 24 MHz within a 1.8 V to 5.5 V range. The device features a 12-bit ADC, 10-bit DAC, ZCD, and multiple timers. It uses a VQFN-28 package and supports I2C, SPI, and USART interfaces.

Feature Summary

• Supports multi-voltage I/O (MVIO) for flexible interfacing
• Includes hardware multiplier and single-cycle I/O access
• Features event system for peripheral signaling
• Provides configurable custom logic look-up tables

Applications

• Industrial control systems
• Smart home appliances
• IoT sensor nodes
• Automotive instrumentation

Procurement Notes

Verify the specific ordering suffixes against official Microchip documentation to ensure correct package type, temperature rating, and carrier configuration. Confirm that the 'T' suffix indicates tape and reel packaging and 'STX' denotes the VQFN28 form factor before finalizing procurement orders.

Selection Notes

Select this model when 16 KB of program memory is sufficient for the application requirements. Consider the VQFN28 package constraints and verify that the 22 available I/O pins meet the interface needs. Ensure the industrial temperature range aligns with the operational environment.

Part Context

This component belongs to the AVR DD Family, designed for high performance and low power consumption. It shares architectural similarities with larger flash variants like the AVR32DD28 and AVR64DD28, allowing for potential vertical migration without code modification.
