Overview
The AVR64DD28-E/SP is an 8-bit microcontroller from the AVR DD family, featuring a 28-pin SPDIP package. It utilizes an AVR CPU with hardware multiplier operating at up to 24 MHz. The device includes 64 KB of in-system self-programmable Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. It supports a supply voltage range of 1.8V to 5.5V and operates within an extended temperature range of -40°C to +125°C.
Feature Summary
- Multi-Voltage I/O (MVIO) capability on Port C for interfacing with different power domains
- Integrated intelligent analog peripherals including a 12-bit ADC, DAC, and Zero-Cross Detector
- Advanced digital peripherals such as Configurable Custom Logic (CCL) and Event System
- Single-pin Unified Program and Debug Interface (UPDI) for programming and debugging
Applications
- Industrial control systems requiring robust noise immunity
- Smart home appliances with multi-voltage requirements
- IoT sensor nodes utilizing low-power architecture
- Automotive applications meeting extended temperature standards
Procurement Notes
Verify the specific ordering suffix 'E' confirms the extended temperature range (-40°C to +125°C) and 'SP' indicates the SPDIP package style. Ensure compatibility with existing designs by confirming pinout alignment with other AVR DD family members. Cross-reference the datasheet revision DS40002315C for any updates regarding fuse settings or peripheral configurations before finalizing procurement.
Selection Notes
Select this component when vertical migration within the AVR DD family is required without code modification. It is suitable for designs needing high-performance analog features alongside standard digital I/O. Consider the extended temperature rating if the application environment exceeds industrial limits. Verify that the 28-pin footprint accommodates the SPDIP package dimensions in the target PCB layout.
Part Context
This part belongs to the AVR DD family, which emphasizes kernel-independent peripherals and smart analog capabilities. It shares architectural similarities with other AVR DD devices, allowing for easy scaling across pin counts and memory sizes. The family targets applications demanding real-time control and efficient power management.
Replacement Considerations
AVR64DD28-I/SP offers identical functionality but with an industrial temperature range (-40°C to +85°C). Other AVR DD family members provide vertical migration options with varying pin counts and memory sizes while maintaining full pin and feature compatibility.
