AVR64DA28-E/SS

Overview

The AVR64DA28-E/SS is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz CPU, 64 KB Flash, 8 KB SRAM, and 512 B EEPROM. It includes a 12-bit ADC with 10 channels, three analog comparators, one 10-bit DAC, three zero-cross detectors, and a Peripheral Touch Controller. The device supports up to six USARTs, two SPIs, and two TWIs within a 28-pin SSOP package.

Feature Summary

Supports vertical migration across the AVR DA(S) family without code modification due to full pin and feature compatibility.
Integrates a Peripheral Touch Controller (PTC) with Driven Shield+ and Boost Mode technologies for capacitive touch applications.
Provides a Program and Debug Interface Disable (PDID) mechanism to prevent unauthorized access to reprogrammable Flash memory over UPDI.

Applications

Capacitive touch interfaces using buttons, sliders, wheels, and 2D surfaces
Secure firmware upgrades requiring application authentication
Power control systems utilizing optimized Timer/Counter type D

Procurement Notes

Verify that the specific ordering suffix matches the required temperature range and package style. Confirm whether the PDID security feature is enabled in the target configuration. Ensure the selected variant aligns with the necessary I/O count and peripheral availability for the design.

Selection Notes

Select this component when 64 KB of program memory and 8 KB of data RAM are sufficient for the application logic. Choose the extended temperature grade (-40°C to +125°C) for environments exceeding industrial limits. Verify that the 28-pin form factor accommodates the required number of general-purpose I/O pins.

Part Context

This device belongs to the AVR DA(S) family, which utilizes the latest Microchip technologies for flexible and low-power operation. The family architecture emphasizes intelligent analog features, advanced digital peripherals, and an Event System for predictable inter-peripheral signaling independent of the CPU.

FAQ

How does the PDID feature protect the device?

PDID prevents access to the device's reprogrammable Flash memory over the Unified Program and Debug Interface (UPDI), ensuring that only software stored in the Boot Code section can update the Application Code.
