ATXMEGA64B1-AUR

Overview

The ATXMEGA64B1-AUR is an 8/16-bit AVR XMEGA microcontroller featuring a 32 MHz CPU, 64 KB flash, 4 KB SRAM, and 2 KB EEPROM. It operates between 1.6 V and 3.6 V across -40°C to +85°C. The device includes a USB 2.0 interface, two USARTs, AES/DES crypto engine, LCD controller, two 12-bit ADCs, and four analog comparators. It utilizes a 100-lead TQFP package with 53 programmable I/O pins.

Feature Summary

Integrates a high-performance AVR RISC CPU with single-cycle execution and hardware multiplier
Includes a dedicated USB 2.0 full-speed device interface with flexible endpoint configuration
Features advanced cryptographic capabilities via integrated AES and DES engines
Supports capacitive touch sensing through the QTouch library for buttons, sliders, and wheels

Applications

Industrial control systems
Factory automation equipment
Medical devices
HVAC and building control units
Utility metering applications

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the 100-lead TQFP form factor. Confirm that the selected revision matches the required firmware development tools and programming interfaces.

Selection Notes

Select this component when a balance of processing power and peripheral richness is required for embedded designs. The inclusion of a hardware crypto engine and USB interface makes it suitable for secure communication applications. Evaluate memory requirements carefully as the 64 KB flash limits complex application storage compared to larger family members.

Part Context

This part belongs to the AVR XMEGA B1 series, designed for low-power, high-performance applications. It shares architectural similarities with other XMEGA devices but offers specific peripheral configurations tailored for industrial and consumer electronics. The series emphasizes energy efficiency without compromising processing speed or connectivity options.
