Overview
The AVR64DA48T-E/6LX 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 utilizes a VQFN-48 package (suffix 6LX) with an extended temperature range of -40°C to +125°C (suffix E). Key peripherals include a 12-bit ADC, three analog comparators, a Peripheral Touch Controller (PTC), and multiple communication interfaces such as USART, SPI, and TWI.
Feature Summary
- Supports vertical migration within the AVR DA(S) family without code modification due to pin and feature compatibility.
- Includes Program and Debug Interface Disable (PDID) for secure firmware upgrades and authentication.
- Features an integrated Peripheral Touch Controller (PTC) with Driven Shield+ technology for capacitive touch applications.
Applications
- Secure firmware upgrade implementations requiring PDID protection
- Capacitive touch interface designs using PTC channels
- Industrial control systems operating in extended temperature environments
Procurement Notes
Verify that the 'E' suffix confirms the extended temperature range (-40°C to +125°C) and the '6LX' suffix corresponds to the VQFN-48 package style. Confirm the 'T' indicates tape and reel packaging. Ensure the specific part number matches the required memory size and peripheral configuration for your design.
Selection Notes
Select this component if your application requires the specific VQFN-48 form factor combined with the extended industrial temperature rating. The device offers high I/O density and advanced analog features like the PTC and ZCD, suitable for complex embedded control tasks requiring secure boot capabilities.
Part Context
This part belongs to the AVR64DA28/32/48/64(S) series, which shares a common architecture and instruction set. Devices in this series are designed for horizontal and vertical migration, allowing designers to scale pin counts or memory sizes while maintaining software compatibility across the family.
Replacement Considerations
AVR64DA48-E/PT is a compatible alternative offering identical electrical and functional specifications but packaged in TQFP-48 instead of VQFN-48. Other family members like AVR64DA64 provide more pins but require layout adjustments.
