Overview
The AVR64DA28T-E/SS is an 8-bit microcontroller from the AVR DA(S) family, featuring a 24 MHz CPU, 64 KB Flash, 8 KB SRAM, and 512 B EEPROM. It operates within a 1.8 V to 5.5 V supply range across -40°C to +125°C temperatures. The device includes a Peripheral Touch Controller (PTC), Configurable Custom Logic (CCL), Event System, and Program and Debug Interface Disable (PDID). It utilizes a single-pin UPDI for programming and debugging.
Feature Summary
- Integrates a Peripheral Touch Controller (PTC) with Driven Shield+ technology for capacitive touch sensing.
- Features Configurable Custom Logic (CCL) allowing hardware-based logic implementation without CPU intervention.
- Includes Program and Debug Interface Disable (PDID) to secure firmware against unauthorized access or modification.
- Supports vertical migration within the AVR DA(S) family while maintaining pin and feature compatibility.
Applications
- Embedded systems requiring secure firmware updates
- Industrial control applications with capacitive user interfaces
- Low-power sensor nodes utilizing event-driven architectures
Procurement Notes
Verify that the ordering suffix 'T' corresponds to Tape & Reel packaging and 'E' indicates Extended temperature range (-40°C to +125°C). Confirm the 'S' designation in the base model implies PDID support if security features are required. Ensure the SSOP-28 package matches your PCB footprint requirements.
Selection Notes
Select this component when a balance of memory capacity and advanced analog peripherals like PTC is needed. The extended temperature rating makes it suitable for harsh environments. Consider the TCA, TCB, and TCD timer configurations for precise timing control needs.
Part Context
This part belongs to the AVR DA(S) family, which offers vertical migration capabilities. It shares architectural similarities with other devices in the series but is distinguished by its specific 64 KB Flash size and 28-pin SSOP package configuration.
Replacement Considerations
AVR64DA28-I/SS provides the same specifications with Industrial temperature range instead of Extended.
FAQ
What does the 'S' suffix indicate in the AVR64DA28S model?
The 'S' suffix indicates that the device includes the Program and Debug Interface Disable (PDID) feature for enhanced security.
How does the Event System benefit peripheral interaction?
The Event System allows peripherals to communicate directly without CPU intervention, enabling predictable and low-latency inter-peripheral signaling.
