AVR64DD28-I/SS

Overview

The AVR64DD28-I/SS is an 8-bit microcontroller from the AVR DD Family, utilizing the AVR CPU with a hardware multiplier and operating at clock speeds up to 24 MHz. It features 64 KB of in-system self-programmable Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. The device is housed in a 28-pin SSOP package and supports a supply voltage range of 1.8V to 5.5V. Key peripherals include a 12-bit ADC, 10-bit DAC, analog comparator, zero-cross detector, and multiple timers.

Feature Summary

Multi-Voltage I/O (MVIO) capability on PORTC for level shifting without external components
Configurable Custom Logic (CCL) with four programmable Look-up Tables (LUTs)
Event System (EVSYS) enabling CPU-independent inter-peripheral signaling
Single-pin Unified Program and Debug Interface (UPDI)

Applications

Industrial control systems requiring real-time processing
Smart home appliances with multi-voltage domain requirements
IoT devices needing low-power operation and efficient peripheral communication

Procurement Notes

Verify the specific ordering suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C). Confirm the package style 'SS' matches the required SSOP footprint. Ensure the datasheet version aligns with current manufacturing specifications before finalizing procurement orders.

Selection Notes

Select this component when 64 KB of program memory and 8 KB of RAM are required within a 28-pin form factor. The MVIO feature is critical for designs interfacing with mixed-voltage peripherals. Consider the AVR DD family's vertical migration capabilities if future pin count expansion is anticipated without code modification.

Part Context

This part belongs to the AVR DD Family, which emphasizes intelligent analog features and advanced digital peripherals. It shares architectural compatibility with other members like the AVR32DD28 and AVR16DD28, allowing for horizontal migration based on memory or pin requirements while maintaining software portability.
