Microcontrollers datasheet and documents for ATMEGA8HVA-4TUR

ATMEGA8HVA-4TUR

Microcontrollers Overview

The ATMEGA8HVA-4TUR is an 8-bit AVR microcontroller designed for smart battery applications. It features 8K bytes of In-System Programmable Flash, 256 bytes EEPROM, and 512 bytes SRAM. The device operates at a maximum frequency of 4 MHz with a supply voltage range of 1.8V to 9V. It includes a 12-bit ADC, high-resolution Coulomb Counter ADC, and autonomous battery protection circuitry. The component is housed in a 36-pad LGA package.

Microcontrollers Feature Summary

Integrated autonomous battery protection module for charge and discharge control
High-resolution Coulomb Counter ADC for accurate current measurement
On-chip step-up and linear voltage regulator supporting single-cell operation
Secure authentication features for battery pack identification

Microcontrollers Applications

Smart battery packs for portable electronics
Lithium-ion battery management systems
Battery monitoring and protection circuits
Fuel gauge implementations

Microcontrollers Procurement Notes

Verify the specific speed grade suffix '4' corresponds to the 4 MHz operational requirement. Confirm the LGA package type matches the PCB footprint design. Ensure the source documentation supports the inclusion of secure authentication features, as these may be subject to separate licensing or NDA agreements.

Microcontrollers Selection Notes

Select this component for applications requiring integrated fuel gauging and protection without external discrete components. Consider the 8K Flash limit for complex algorithms. Evaluate the 36-pad LGA package for assembly feasibility compared to TSOP alternatives. Verify voltage requirements align with the 1.8V to 9V operating range.

Microcontrollers Part Context

This part belongs to the AVR Smart Battery family, specifically the HVA series. It shares architectural similarities with the ATmega16HVA but offers reduced program memory capacity. The device integrates specialized analog peripherals for battery monitoring directly onto the MCU die, distinguishing it from general-purpose AVR controllers.
