ATXMEGA64A1-C7U

Overview

The ATXMEGA64A1-C7U is an 8/16-bit microcontroller based on the AVR XMEGA A1 architecture. It features 64KB of in-system self-programmable flash memory, 2KB EEPROM, and 4KB internal SRAM. The device operates within a supply voltage range of 1.6V to 3.6V. It supports clock frequencies up to 32MHz when powered by 2.7V or higher, and up to 12MHz from 1.6V. The component is housed in a 100-ball VFBGA package with 78 programmable I/O pins.

Feature Summary

• High-performance AVR RISC CPU executing instructions in a single clock cycle
• Integrated AES and DES cryptographic engine for secure data processing
• Four-channel DMA controller supporting simultaneous bus access
• Eight-channel event system enabling peripheral-to-peripheral communication

Applications

• Industrial control systems
• HVAC and building control
• Medical applications
• Utility metering
• Factory automation

Procurement Notes

Verify that the ordering suffix C7U corresponds to the 100-ball VFBGA package variant. Confirm the specific revision status as the datasheet indicates this series may be superseded by newer generations. Ensure compatibility with required operating temperatures and voltage levels before finalizing procurement specifications.

Selection Notes

Select this model for designs requiring high I/O density in a compact footprint. The VFBGA package offers space efficiency compared to TQFP alternatives. Consider the available boot section size if bootloader functionality is required. Evaluate power consumption requirements against the five selectable sleep modes provided by the architecture.

Part Context

This component belongs to the Atmel AVR XMEGA A1 family of microcontrollers. It shares architectural similarities with other devices in the series, such as the ATxmega128A1, differing primarily in memory capacities. The family emphasizes low power consumption combined with high throughput capabilities suitable for embedded control applications.
