AVR64DA64ST-I/5LX

Overview

The AVR64DA64ST-I/5LX is an 8-bit microcontroller from the AVR DA(S) family, utilizing the AVR CPU with a hardware multiplier. It operates at up to 24 MHz and features 64 KB of Flash memory, 8 KB of SRAM, and 512 B of EEPROM. The device includes a 12-bit differential ADC, three analog comparators, a 10-bit DAC, and up to six USARTs. It supports UPDI for programming and debugging. The part is housed in a VQFN48 package (suffix 5LX), designed for industrial temperature ranges (-40°C to +85°C).

Feature Summary

Supports Program and Debug Interface Disable (PDID) for secure firmware protection.
Includes Peripheral Touch Controller (PTC) with Driven Shield+ technology.
Features Configurable Custom Logic (CCL) with programmable Look-up Tables.
Provides Event System for CPU-independent inter-peripheral signaling.

Applications

Industrial control systems requiring real-time processing.
Smart home appliances with capacitive touch interfaces.
IoT sensor nodes needing low-power operation.
Automotive secondary monitoring applications.

Procurement Notes

Verify the specific ordering suffix '5LX' corresponds to the VQFN48 package type as defined in Microchip documentation. Confirm that the 'I' designation matches the required industrial temperature range for your application environment. Ensure compatibility with existing design tools and verify that the PDID feature requirements align with your security protocols before finalizing procurement.

Selection Notes

Select this component when a balance of high I/O count and advanced analog peripherals is needed within a compact footprint. The 64-pin variant offers extensive connectivity compared to smaller packages. Consider the DA family's vertical migration capabilities if future scalability is anticipated. Evaluate the power consumption profiles against system requirements, particularly regarding sleep modes and clock options.

Part Context

This MCU belongs to the AVR DA(S) family, which shares architectural similarities with other AVR devices but introduces enhanced analog and digital peripherals. It is designed for applications requiring robust security features and flexible I/O configurations. The family supports seamless code migration between different pin counts and memory sizes, facilitating product line expansion without significant software rewrites.
