ATXMEGA64D3-ANR

Overview

The ATXMEGA64D3-ANR is an 8-bit microcontroller from the AVR XMEGA D3 series, manufactured by Microchip Technology. It features a 32 MHz AVR core with 64 kB of Flash program memory, 4 kB of SRAM, and 2 kB of EEPROM. The device operates within a supply voltage range of 1.6 V to 3.6 V and supports a maximum clock frequency of 32 MHz. It includes a 12-bit ADC with 16 channels, five timers/counters, and interfaces such as SPI, USART, and I2C. The component is housed in a 64-pin TQFP package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-performance 8-bit AVR RISC core capable of executing complex instructions in a single clock cycle.
• Provides flexible communication capabilities through multiple serial peripheral interfaces including SPI, USART, and TWI/I2C.
• Features a 12-bit analog-to-digital converter with up to 16 input channels for precise signal acquisition.
• Supports low-power operation modes with fast wake-up times enabled by real-time counter functionality.

Applications

• Industrial control systems requiring robust processing and reliable communication interfaces
• Building automation and climate control applications utilizing sensor data acquisition
• Utility meters and instrumentation devices needing accurate analog measurement capabilities

Procurement Notes

Verify the specific suffix 'ANR' against official Microchip documentation to confirm package type and tape-and-reel availability. Ensure compatibility with required operating temperatures and voltage levels. Confirm RoHS compliance status for your region. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a balance of moderate memory capacity and rich peripheral set is required. The 64-pin TQFP package offers ample I/O options for complex designs. Consider the 32 MHz speed and low-power features for battery-operated or thermally constrained environments. Evaluate alternative packages if space constraints differ from the standard TQFP dimensions.

Part Context

This part belongs to the AVR XMEGA D3 family, designed for applications demanding high code density and low power consumption. The D3 series emphasizes energy efficiency without sacrificing performance, making it suitable for cost-sensitive embedded solutions. It shares architectural similarities with other XMEGA devices but offers specific memory and peripheral configurations tailored for general-purpose microcontroller tasks.

Replacement Considerations

Direct substitutes include ATXMEGA64D3-AU or ATXMEGA64D3-AUR, differing primarily in packaging (TQFP vs. QFN) and reel format. Verify pin compatibility and thermal specifications when swapping between these variants. No other direct replacements are confirmed in public documentation.
