Overview
The AVR64DA48-I/6LX is an 8-bit microcontroller from the AVR DA family, featuring a 24 MHz AVR CPU with hardware multiplier. It includes 64 KB of Flash, 8 KB of SRAM, and 512 B of EEPROM. The device utilizes a VQFN-48 package (suffix 6LX) and supports industrial temperatures (-40°C to +85°C). Key peripherals include up to six USARTs, two SPIs, two TWIs, a 12-bit ADC, three analog comparators, a DAC, and a Peripheral Touch Controller.
Feature Summary
- Features a flexible low-power architecture with an Event System for CPU-independent inter-peripheral signaling.
- Includes intelligent analog subsystems such as a 12-bit differential ADC with programmable gain and window-compare analog comparators.
- Supports secure firmware upgrades through Program and Debug Interface Disable (PDID) mechanisms.
- Integrates advanced digital peripherals including Configurable Custom Logic (CCL) and a Peripheral Touch Controller.
Applications
- Industrial control systems requiring robust I/O and communication interfaces
- Smart home appliances utilizing capacitive touch controls via PTC
- Power management applications using Timer/Counter type D (TCD)
- Secure embedded devices needing code protection features
Procurement Notes
Verify the specific ordering suffix '6LX' corresponds to the VQFN-48 package configuration required for your PCB layout. Confirm that the 'I' temperature grade meets your operational environment specifications. Ensure compatibility with the UPDI programming interface for development and debugging workflows.
Selection Notes
Select this component when pin count flexibility and vertical migration within the AVR DA family are required. It is suitable for designs needing high-speed serial communication (up to six USARTs) and precise analog signal processing. Consider the VQFN-48 footprint constraints and thermal dissipation capabilities during the mechanical design phase.
Part Context
This part belongs to the AVR64DA28/32/48/64(S) family, which offers horizontal and vertical migration capabilities without code modification. The AVR DA family represents Microchip's latest technology integration, combining standard AVR CPU performance with enhanced peripheral sets like the Peripheral Touch Controller and advanced event routing systems.
Replacement Considerations
AVR64DA48-I/PT: Same memory and peripherals in TQFP-48 package. AVR64DA48-E/6LX: Extended temperature range (-40°C to +125°C) in identical VQFN-48 package. AVR64DA32-I/6LX: Reduced pin count and I/O availability.
