ATXMEGA64B3-ANR

Overview

The ATXMEGA64B3-ANR is an 8/16-bit microcontroller from the AVR XMEGA B3 family. It features 64KB of in-system self-programmable flash, 2KB EEPROM, and 4KB SRAM. The device operates at frequencies up to 32MHz with a supply voltage range of 1.6V to 3.6V. Key peripherals include a USB 2.0 full-speed interface, two-channel DMA controller, four-channel event system, one USART with IrDA support, AES/DES crypto engine, and an 8-channel 12-bit ADC. It is housed in a 64-lead TQFP package.

Feature Summary

Integrated USB 2.0 full-speed device interface with flexible endpoint configuration
Hardware cryptographic engine supporting AES and DES algorithms
Capacitive touch sensing capabilities via QTouch library support
Liquid Crystal Display controller with built-in contrast control and ASCII mapping

Applications

Industrial control systems
Building and climate control units
Utility metering applications
Medical devices
HVAC systems

Procurement Notes

Verify the specific ordering suffix 'ANR' against official Microchip documentation to confirm tape and reel packaging and temperature grade. Confirm current production status as availability may vary. Ensure compatibility with existing design files before procurement.

Selection Notes

Select this component for applications requiring integrated USB connectivity and cryptographic security within a low-power 8/16-bit architecture. The B3 series offers high performance per megahertz, suitable for battery-powered devices needing fast wake-up times and extensive peripheral integration.

Part Context

This part belongs to the AVR XMEGA B3 microcontroller family, designed for high-performance, low-power embedded applications. The family utilizes picoPower technology to maintain low sleep currents regardless of memory size, optimizing battery life for devices spending most time in sleep mode.

Replacement Considerations

Consult official datasheets for cross-referencing. Verify pinout and peripheral compatibility with potential substitutes such as other XMEGA B3 variants or newer Microchip MCU families.
