ATXMEGA64D4-CUR

Overview

The ATXMEGA64D4-CUR is an 8/16-bit microcontroller from the AVR XMEGA D4 family, manufactured by Microchip Technology. It features 64KB of in-system self-programmable flash memory, 2KB of EEPROM, and 4KB of internal SRAM. The device operates on a supply voltage ranging from 1.6V to 3.6V and supports clock frequencies up to 32MHz when powered at 2.7V or higher. It is housed in a 49-ball VFBGA package with a -40°C to +85°C industrial temperature range.

Feature Summary

• Supports capacitive touch sensing via QTouch library integration for buttons, sliders, and wheels
• Includes a four-channel event system for direct peripheral-to-peripheral communication without CPU intervention
• Features a high-resolution timer/counter system with advanced waveform extensions
• Provides a twelve-channel, 12-bit Analog to Digital Converter with optional differential inputs

Applications

• Industrial control systems
• Building and climate control units
• Utility metering applications
• Low power battery operated devices

Procurement Notes

Verify the specific ordering suffix 'CUR' corresponds to the tape and reel packaging format as documented in the official datasheet. Confirm that the component meets RoHS compliance standards and halide-free requirements specified for this product line. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the silicon.

Selection Notes

Select this component for designs requiring high performance combined with low power consumption in a compact footprint. The 64KB flash capacity accommodates complex firmware while the extensive peripheral set reduces external component count. Consider the VFBGA package constraints regarding thermal management and PCB layout density during the hardware design phase.

Part Context

This part belongs to the AVR XMEGA D4 series, which utilizes picoPower technology to scale low-power characteristics across different memory sizes. The series is designed for embedded applications needing fast wake-up times and full SRAM retention in sleep modes. It shares architectural similarities with other D4 variants but offers specific memory and package configurations tailored for space-constrained industrial environments.
