ATXMEGA8E5-MNR

Overview

The ATXMEGA8E5-MNR is an 8/16-bit microcontroller from the AVR XMEGA E5 family, manufactured by Microchip Technology. It features 8KB of in-system self-programmable flash memory, 1KB of internal SRAM, and 512 bytes of EEPROM. The device operates at a maximum frequency of 32MHz with a supply voltage range of 1.6V to 3.6V. It utilizes a 32-lead VQFN (5x5mm) package and supports an operating temperature range of -40°C to 105°C.

Feature Summary

• High-performance 8/16-bit architecture executing instructions in a single clock cycle for optimized power consumption versus processing speed.
• Integrated four-channel enhanced DMA controller and eight-channel event system for asynchronous signal routing and peripheral management.
• Includes high-resolution PWM extensions capable of down to 4ns resolution and waveform extensions for motor and lighting control.
• Features a sixteen-channel 12-bit ADC with offset/gain correction and averaging, alongside a two-channel 12-bit DAC.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'MNR' corresponds to the 32-VQFN (5x5mm) package and industrial temperature grade (-40°C to 105°C). Confirm that the tape and reel packaging format aligns with automated assembly requirements. Cross-reference the datasheet revision history to ensure compatibility with current manufacturing standards.

Selection Notes

Select this component when a compact 32-pin footprint is required for space-constrained designs. The extended temperature range makes it suitable for industrial environments where standard commercial grade parts may fail. Ensure the application benefits from the integrated high-resolution timer extensions and DMA capabilities for efficient data handling.
