ATXMEGA8E5-MUR

Overview

The ATXMEGA8E5-MUR is an 8/16-bit microcontroller from the AVR XMEGA E5 family, manufactured by Microchip Technology. It features a 32-lead VQFN package (5x5mm) and operates within a supply voltage range of 1.6V to 3.6V. The device includes 8KB of in-system self-programmable flash memory, 1KB of internal SRAM, and 512Bytes of EEPROM. It supports a maximum clock frequency of 32MHz and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports high-performance processing with single-cycle instruction execution for optimized power consumption versus speed.
• Integrates a four-channel enhanced DMA controller and an eight-channel event system for asynchronous signal routing.
• Includes a sixteen-channel, 12-bit Analog to Digital Converter with offset/gain correction and oversampling capabilities.
• Features two USARTs, one SPI interface, and a Two-Wire Interface compatible with I2C and SMBus protocols.

Applications

• Board controller
• Sensor control
• Motor control
• Industrial control

Procurement Notes

Verify that the ordering suffix 'R' corresponds to the Tape and Reel packaging format as specified in the official datasheet. Confirm the specific revision level matches project requirements, noting potential errata associated with device revisions A or B. Ensure compatibility with the 32Z package dimensions during PCB layout.

Selection Notes

Select this component when a compact 32-pin footprint is required alongside robust analog conversion features. The inclusion of a 12-bit DAC and programmable Brown-out detection makes it suitable for precision applications. Consider the 32MHz operating speed relative to the 1.6V minimum supply voltage constraints.

Part Context

This part belongs to the AVR XMEGA E5 series, which provides a balance of low power consumption and rich peripheral integration. The E5 family distinguishes itself with specialized modules like the Waveform Extension and High Resolution Extension for advanced motor and lighting control applications.
