Overview
The AVR16DD28-E/SP is an 8-bit microcontroller from the AVR DD family, featuring a 16 KB Flash memory, 2 KB SRAM, and 256 bytes of EEPROM. It operates at clock speeds up to 24 MHz with a supply voltage range of 1.8V to 5.5V. The device includes a 12-bit ADC, 10-bit DAC, two USARTs, SPI, TWI/I2C, and Multi-Voltage I/O (MVIO). It is housed in a 28-pin SPDIP package and supports an extended operating temperature range of -40°C to +125°C.
Feature Summary
- Multi-Voltage I/O (MVIO) on PORT C enables bidirectional communication across different power domains without external level shifters.
- Configurable Custom Logic (CCL) provides four Look-Up Tables for hardware-based logic implementation independent of CPU processing.
- Event System (EVSYS) allows direct inter-peripheral signaling to reduce system latency and CPU overhead.
- Integrated intelligent analog peripherals include a 12-bit differential ADC, 10-bit DAC, Analog Comparator, and Zero-Cross Detector.
Applications
- Industrial control systems requiring robust noise immunity and multi-voltage domain interfacing
- Smart home appliances utilizing low-power operation and real-time control features
- Internet of Things (IoT) nodes needing efficient peripheral handling via the Event System
- Automotive applications meeting ISO 26262 functional safety requirements
Procurement Notes
Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and 'SP' indicates the 28-pin SPDIP package. Confirm the specific revision status against the manufacturer's latest documentation to ensure compatibility with current production standards.
Selection Notes
Select this component when vertical migration within the AVR DD family is required without code modification. Ensure the design utilizes the Multi-Voltage I/O capabilities if interfacing with devices operating at different supply voltages. Verify that the 16 KB Flash and 2 KB SRAM meet the application's memory constraints.
Part Context
This part belongs to the AVR DD family, which offers pin-and-feature compatible horizontal and vertical migration options. It shares the same core architecture as higher-memory variants like the AVR32DD28 and AVR64DD28, allowing for scalable design transitions while maintaining software compatibility.
Replacement Considerations
AVR16DD28-I/SP serves as a direct replacement for industrial temperature range applications. For surface-mount needs, consider AVR16DD28T-E/SS or AVR16DD28-I/SS. Ensure the substitute matches the required temperature grade and package type.
