ATXMEGA8E5-ANR

Overview

The ATXMEGA8E5-ANR 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 within a supply voltage range of 1.6V to 3.6V and supports a maximum clock frequency of 32MHz. It utilizes a 32-lead TQFP package (7x7mm) with an extended industrial temperature range of -40°C to +105°C. The 'ANR' suffix indicates tape and reel packaging.

Feature Summary

• Supports high-performance processing with single-cycle instruction execution for optimized power consumption versus speed.
• Includes four-channel enhanced DMA controller and eight-channel event system for asynchronous signal routing.
• Features three 16-bit timer/counters with high-resolution PWM extension and waveform generation capabilities.
• Integrates a sixteen-channel 12-bit ADC with offset/gain correction and a two-channel 12-bit DAC.

Applications

• Motor control systems
• Industrial control applications
• Battery chargers
• Utility metering devices

Procurement Notes

Verify the ordering code matches ATXMEGA8E5-ANR to confirm the specific package type and temperature rating. Ensure the required quantity aligns with tape and reel specifications. Confirm RoHS compliance and halide-free status as per manufacturer standards. Check for any recent production changes or notices affecting this specific part number before finalizing orders.

Selection Notes

Select this component when an extended industrial temperature range (-40°C to +105°C) is required compared to standard commercial variants. Choose the tape and reel format for automated surface-mount assembly processes. Consider the 32-pin count and peripheral richness if space-constrained designs need integrated analog and digital interfaces without external components.

Part Context

This device belongs to the AVR XMEGA E5 family, which offers high performance and low power consumption. It shares architectural similarities with other E5 variants but differs in memory size and package options. The E5 series is designed for applications requiring robust peripheral integration and efficient power management in compact form factors.

Replacement Considerations

ATXMEGA8E5-AU serves as a tray-packaged alternative with identical electrical characteristics. ATXMEGA8E5-MN and ATXMEGA8E5-M4U offer different package footprints (VQFN and UQFN) while maintaining the same core functionality and pinout compatibility where applicable.
