AVR64DA28-I/SS

Overview

The AVR64DA28-I/SS is an 8-bit microcontroller from the AVR DA family, featuring a 28-pin SSOP package. It operates at a maximum frequency of 24 MHz and includes 64 KB of Flash memory, 8 KB of SRAM, and 512 B of EEPROM. The device supports a supply voltage range of 1.8 V to 5.5 V and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a Peripheral Touch Controller (PTC) for capacitive touch sensing applications
• Includes Program and Debug Interface Disable (PDID) for secure firmware protection
• Features a 12-bit differential ADC with up to 130 ksps conversion speed
• Supports single-pin Unified Program and Debug Interface (UPDI) for programming

Applications

• Capacitive touch control interfaces
• Secure embedded system development
• Industrial automation controllers
• Low-power consumer electronics

Procurement Notes

Verify that the ordering suffix 'I' confirms the industrial temperature range (-40°C to +85°C). Confirm the 'SS' suffix corresponds to the SSOP-28 package type. Ensure the specific part number matches the required pin count and memory configuration before finalizing procurement orders.

Selection Notes

Select this component when vertical migration within the AVR DA(S) family is required without code modification. Choose this model if the design necessitates exactly 28 pins while retaining full feature compatibility with larger pin-count variants in the same series.

Part Context

This device belongs to the AVR DA(S) family, which utilizes the latest Microchip technologies for flexible and low-power architectures. The family supports horizontal migration to reduce pin counts and vertical migration without code changes, ensuring scalability across different application requirements.
