Procurement Notes
Verify the specific ordering code ATXMEGA64B1-ANR against official Microchip documentation to confirm the tape and reel packaging suffix and industrial temperature grade. Ensure compatibility with the 100-lead TQFP footprint during PCB design. Cross-reference datasheet revision Atmel-8330H-AVR-ATxmega64B1-128B1_Datasheet.pdf for accurate pinout and electrical characteristics.
Selection Notes
Select this component when requiring a balance of high performance and low power consumption in the AVR XMEGA architecture. The industrial temperature range makes it suitable for demanding environments. Consider the available memory sizes and peripheral sets, such as the LCD controller and crypto engine, to determine if it meets the specific application requirements compared to other B1 series variants.
Part Context
This device belongs to the AVR XMEGA B1 microcontroller family, designed with picoPower technology for scalable low-power operation. The family offers large memory ranges with reduced sleep current, enabling extended battery life in portable applications. It supports fast wake-up times and efficient interrupt handling through a programmable multilevel interrupt controller.
Replacement Considerations
The ATXMEGA64B1-AUR is a compatible alternative within the same package and specification profile. Verify that any substitute maintains the 100-lead TQFP form factor and the -40°C to +105°C temperature range to ensure direct interchangeability without hardware redesign.
