ATMEGA8HVD-4MX

Overview

The ATMEGA8HVD-4MX is an 8-bit AVR microcontroller featuring a high-voltage serial programming interface. It integrates 8KB of in-system programmable Flash memory, 512 bytes of EEPROM, and 1KB of SRAM. The device operates at clock frequencies up to 4MHz with supply voltages ranging from 2.1V to 8V. It utilizes an 18-pad MLF package measuring 3.5x6.5mm with a staggered dual-row configuration.

Feature Summary

Supports high-voltage serial programming for robust development and manufacturing workflows
Integrates non-volatile Flash, EEPROM, and volatile SRAM on a single chip
Operates across a wide voltage range suitable for diverse power environments

Applications

Industrial control systems requiring reliable data storage
Battery-powered devices utilizing low voltage operation
Embedded applications needing in-system programmability

Procurement Notes

Verify the specific suffix '4MX' against official Microchip documentation to confirm the package type and temperature range. Ensure the component matches the 18-pad MLF specification. Cross-reference datasheet revisions to validate electrical characteristics before integration into final designs.

Selection Notes

Select this model when high-voltage serial programming compatibility is required alongside standard AVR functionality. Consider the 4MHz maximum frequency and 8KB Flash capacity relative to application code size. Evaluate the 18-pad MLF footprint against available PCB space constraints.

Part Context

This component belongs to the ATmega8HVD family, which distinguishes itself through support for high-voltage serial programming. This feature simplifies production programming compared to standard parallel or low-voltage serial interfaces. The device maintains compatibility with standard AVR instruction sets while offering enhanced manufacturing flexibility.

Replacement Considerations

Consult official Microchip substitution guides for verified alternatives. Generic AVR replacements may lack the specific high-voltage serial programming capability or identical pinout configuration.
