Overview
The AVR16DD28T-E/STX is an 8-bit microcontroller from the AVR DD Family, featuring a 16 KB Flash memory, 2 KB SRAM, and 256 B EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8 V to 5.5 V. The device includes a 12-bit ADC with 19 channels, a 10-bit DAC, two USARTs, SPI, TWI/I2C, and Multi-Voltage I/O (MVIO). It utilizes a VQFN-28 package and supports extended temperature operation from -40°C to +125°C.
Feature Summary
- Features Multi-Voltage I/O (MVIO) on PORT C for flexible voltage level interfacing
- Includes intelligent analog peripherals such as a 12-bit differential ADC and Zero-Cross Detector
- Supports CPU-independent inter-peripheral signaling via the Event System
- Provides Configurable Custom Logic (CCL) with programmable Look-up Tables
Applications
- Industrial control systems requiring real-time processing
- Smart home appliances and IoT devices
- Automotive applications within specified temperature ranges
- Battery-powered equipment utilizing low-power sleep modes
Procurement Notes
Verify that the ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'STX' specifies the VQFN-28 tape and reel packaging. Ensure compatibility with the AVR DD Family pinout if migrating from other variants in the series. Confirm that the specific revision matches the required datasheet version DS40002315C for accurate peripheral specifications.
Selection Notes
Select this component when 16 KB of program memory is sufficient for the application logic. It is suitable for designs requiring multi-voltage I/O capabilities without external level shifters. Consider this part over higher-memory variants if cost and board space are constrained while maintaining access to advanced analog features like the 12-bit ADC and ZCD.
Part Context
This device belongs to the AVR DD Family, which emphasizes vertical migration compatibility across different memory sizes and pin counts. It shares architectural similarities with the AVR32DD and AVR64DD series, allowing code reuse. The family integrates modern features like the Event System and CCL, distinguishing it from older AVR architectures.
Replacement Considerations
AVR16DD28T-I/STX offers the same functionality with an industrial temperature range (-40°C to +85°C). AVR32DD28T-E/STX provides increased memory capacity while maintaining pin compatibility.
