Overview
The ATXMEGA64D3-MNR is an 8-bit AVR XMEGA D3 microcontroller featuring a 64 kB Flash program memory, 2 kB EEPROM, and 4 kB SRAM. It operates within a voltage range of 1.6 V to 3.6 V and supports a maximum clock frequency of 32 MHz. The device utilizes a 64-pin QFN package with exposed pad and provides 50 I/O lines. Key peripherals include a 12-bit ADC, multiple timers/counters, and communication interfaces such as SPI, TWI, and USART.
Feature Summary
- Integrates high-performance 8-bit AVR architecture with picoPower low-power technology for extended battery life in sleep modes.
- Includes a DMA controller and event system to offload data transfer and inter-peripheral signaling from the CPU core.
- Features a 12-bit analog-to-digital converter (ADC) with up to 16 channels for precise signal acquisition.
Applications
- Battery-powered thermostats requiring large memory and fast wake-up times
- Building and climate control systems with display interfaces
- Utility meters equipped with RF or ZigBee connectivity modules
Procurement Notes
Verify the specific suffix 'MNR' against official Microchip documentation to confirm the exact package type and tape-and-reel configuration. Ensure compatibility with surface-mount assembly processes and check for RoHS compliance status in the latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a balance of moderate memory capacity and low power consumption is required. The 64 kB Flash size supports complex software stacks compared to smaller variants. Verify that the 64-pin QFN footprint fits the PCB layout constraints and that the 32 MHz processing speed meets the application's real-time execution requirements.
Part Context
This part belongs to the AVR XMEGA D3 series, designed for applications needing true low-power capabilities alongside larger memory ranges. The family utilizes picoPower technology to maintain consistent sleep current characteristics across different memory sizes, distinguishing it from other MCU families where sleep current scales with memory.
Replacement Considerations
Consult the official Microchip product selector tool for verified cross-reference parts. Check for availability of alternative suffixes such as AU or AUR if package or reel configurations differ. No direct substitute part numbers are confirmed in the provided source material.
