8-Kbyte self-programming Flash Program Memory, 512-Bytes SRAM, 256-Bytes EEPROM, 1 cell li-ion applications, Over-current, Short-circuit protection, 10-bit ADC, debugWire interface for on-chip debug. Up to 4 MIPS throughput at 4 MHz. 2.0 - 2.4 Volt Operation.

The ATmega4HVD/8HVD is a monitoring and protection circuit for 1-cell Li-ion applications with focus on high security/authentication, low cost and high utilization of the cell energy. The device contains secure authentication features as well as autonomous battery protection during
charging and discharging. The External Protection Input can be used to implement other battery protection mechanisms using external components, e.g. protection against chargers with too high charge voltage can be easily implemented with a few low cost passive components.
The feature set makes the ATmega4HVD/8HVD a key component in any system focusing on high security, battery protection, high system utilization and low cost.
