ATXMEGA64D4-AN

Overview

The ATXMEGA64D4-AN is an 8-bit microcontroller from the AVR XMEGA D4 series, manufactured by Microchip Technology. It features a 32 MHz maximum clock frequency and utilizes the AVR core architecture. The device includes 64 kB of Flash program memory, 4 kB of SRAM data memory, and 2 kB of EEPROM. It operates within a supply voltage range of 1.6 V to 3.6 V and supports surface mount installation in a TQFP-44 package. The component provides 34 I/O lines and supports interfaces including SPI, USART, and I2C.

Feature Summary

• Integrates a high-performance 8-bit/16-bit AVR RISC core with up to 32 MIPS throughput at 32 MHz.
• Includes a 12-bit analog-to-digital converter with multiple channels for precise signal acquisition.
• Features an advanced event system and DMA controller to offload data transfer and peripheral signaling from the CPU.

Applications

• Battery-powered thermostats requiring low sleep current and fast wake-up times.
• Building automation and climate control systems with display interfaces.
• Utility meters equipped with RF or ZigBee connectivity modules.

Procurement Notes

Verify the specific suffix 'AN' against official Microchip documentation to confirm the exact package type and temperature grade, as standard listings often default to 'AU' (TQFP) or 'CU' (VFBGA). Ensure the ordering information matches the required pinout and thermal specifications for the target PCB design before finalizing procurement.

Selection Notes

Select this component when designing applications that require large memory capacity combined with ultra-low power consumption. The XMEGA D4 series is suitable for projects needing fast reaction times from sleep modes while maintaining significant code storage. Consider the TQFP-44 package availability if through-hole or larger pitch surface-mount assembly is preferred over smaller BGA options.

Part Context

This part belongs to the AVR XMEGA D4 family, which emphasizes picoPower technology for consistent low-power performance across varying memory sizes. The D4 series distinguishes itself with integrated USB capabilities and enhanced peripheral sets compared to older A-series variants, targeting modern embedded control applications.
