Overview
The AVR64DD28T-I/SS is an 8-bit microcontroller from the AVR DD family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB of Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports industrial temperatures (-40°C to +85°C). Key peripherals include a 12-bit ADC, 10-bit DAC, analog comparator, zero-cross detector, and multi-voltage I/O (MVIO). It utilizes a 28-pin SSOP package in tape and reel format.
Feature Summary
- Multi-Voltage I/O (MVIO) capability on PORT C for interfacing with different power domains
- Configurable Custom Logic (CCL) with four Look-up Tables for independent peripheral signaling
- Event System (EVSYS) for low-latency inter-peripheral communication without CPU intervention
- Single-pin Unified Program and Debug Interface (UPDI) for programming and debugging
Applications
- Industrial control systems requiring real-time processing
- Smart home appliances with mixed-signal requirements
- IoT devices utilizing multi-voltage sensor interfaces
- Motor control applications using PWM and zero-cross detection
Procurement Notes
Verify the ordering suffix 'I' confirms the -40°C to +85°C industrial temperature rating. Confirm 'SS' indicates the SSOP package and 'T' denotes tape and reel packaging. Ensure the specific part number matches the required pin count and memory configuration before finalizing procurement orders.
Selection Notes
Select this component when 64 KB of program memory and 8 KB of RAM are required alongside advanced analog features like MVIO and ZCD. It is suitable for designs needing vertical migration within the AVR DD family without code modification. Consider the 28-pin footprint constraints and the availability of UPDI for development tools.
Part Context
This part belongs to the AVR64DD32/28 subset of the broader AVR DD family. It shares architectural similarities with other members like the AVR32DD28 and AVR16DD28 but offers higher memory capacity. The device is designed for seamless integration into Microchip's ecosystem, supporting standard development environments and toolchains compatible with the AVR architecture.
Replacement Considerations
AVR64DD28-E/SS provides extended temperature range (+125°C). AVR64DD28-I/SO offers the same electrical specifications in a SOIC package. AVR64DD28T-SS is identical except for potential carrier variations.
