Overview
The ATXMEGA64B3-MUR is an 8/16-bit microcontroller from the AVR XMEGA B3 family, manufactured by Microchip Technology. It features a 64KB in-system self-programmable flash memory, 2KB EEPROM, and 4KB internal SRAM. The device operates at frequencies up to 32MHz with a supply voltage range of 1.6V to 3.6V. It includes a two-channel DMA controller, four-channel event system, USB 2.0 full-speed interface, LCD controller supporting up to 4x25 segments, and an 8-channel 12-bit ADC. The component is housed in a 64-pad QFN package (9x9mm) and is supplied in tape and reel packaging.
Feature Summary
- Integrates a high-performance AVR RISC CPU with single-cycle execution capabilities and hardware multiplier.
- Includes a dedicated Liquid Crystal Display controller with built-in contrast control and ASCII character mapping.
- Features a two-channel DMA controller and four-channel event system for efficient peripheral data handling.
- Provides a full-speed USB 2.0 device interface with flexible endpoint configuration.
Applications
- Industrial control systems
- Building and climate control applications
- Utility metering devices
- Medical equipment interfaces
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm current production status as availability may vary. Ensure compatibility with existing PCB footprints for the 64-QFN package. Check for required development tools or libraries such as QTouch support.
Selection Notes
Select this component for designs requiring integrated LCD driving and USB connectivity within a low-power constraint. Consider the 64KB flash capacity for application complexity. Evaluate the 36 programmable I/O pins against interface requirements. Verify that the 1.6V to 3.6V operating voltage aligns with the system power budget.
Part Context
This part belongs to the AVR XMEGA B3 microcontroller family, which emphasizes picoPower technology for low sleep currents. The series supports linear address mapping for easy migration between different memory sizes within the same family. It utilizes the Program and Debug Interface (PDI) alongside JTAG for programming.
Replacement Considerations
ATXMEGA64B3-AUR is a verified alternative offering identical electrical specifications but utilizing a 64-TQFP package instead of QFN. Both parts share the same core architecture and peripheral set.
