This product is a high performance, low power AVR® 8-bit microcontroller with 131 powerful instructions and most single clock cycle execution. It has 32 x 8 general purpose working registers, fully static operation, and up to 4 MIPS throughput at 4 MHz.
The ATmega8HVA/ATmega16HVA are low‑power 8‑bit AVR microcontrollers designed for Li‑ion battery monitoring and protection. They integrate high‑voltage outputs, a 12‑bit ADC, a high‑resolution coulomb counter, and on‑chip voltage regulation, supporting both 1‑cell and 2‑cell configurations.
The document provides detailed pin configurations for LGA and TSOP packages, memory sizes, electrical characteristics, and programming options, along with a comparison of the two device variants and a disclaimer on preliminary data.
