ATmega16HVA 電子部品, 半導体
The ATmega8HVA/16HVA contains a 12-bit ADC that can be used to measure the voltage of
each cell individually. The ADC can also be used to monitor temperature, either on-chip temper-
ature using the built-in temperature sensor, external temperature using thermistors connected to
dedicated ADC inputs. The ATmega8HVA/16HVA contains a high-voltage tolerant, open-drain
IO pin that supports serial communication. Programming can be done in-system using the 4
General Purpose IO ports that support SPI programming.
The AVR core combines a rich instruction set with 32 general purpose working registers. All the
32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent
registers to be accessed in one single instruction executed in one clock cycle. The resulting
architecture is more code efficient while achieving throughputs up to ten times faster than con-
ventional CISC microcontrollers.
The MCU includes 8K/16K bytes of In-System Programmable Flash with Read-While-Write
capabilities, 256 bytes EEPROM, 512 bytes SRAM, 32 general purpose working registers, 6
general purpose I/O lines, debugWIRE for On-chip debugging and SPI for In-system Program-
ming, two flexible Timer/Counters with Input Capture and compare modes, internal and external
interrupts, a 12-bit Sigma Delta ADC for voltage and temperature measurements, a high resolu-
tion Sigma Delta ADC for Coulomb Counting and instantaneous current measurements,
Additional Secure Authentication Features, an authonomous Battery Protection module, a pro-
grammable Watchdog Timer with wake-up capabilities, and software selectable power saving
modes.
The AVR core combines a rich instruction set with 32 general purpose working registers. All the
32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two indepdent
registers to be accessed in one single instruction executed in one clock cycle. The resulting
architecture is more code efficient while achieving throughputs up to ten times faster than con-
ventional CISC microcontrollers.
The device is manufactured using Atmel’s high voltage high density non-volatile memory tech-
nology. The On-chip ISP Flash allows the program memory to be reprogrammed In-System,
through an SPI serial interface, by a conventional non-volatile memory programmer or by an On-
chip Boot program running on the AVR core. By combining an 8-bit RISC CPU with In-System
Self-Programmable Flash, fuel gauging ADCs, dedicated battery protection circuitry, and a volt-
age regulator on a monolithic chip, the ATmega8HVA/16HVA is a powerful microcontroller that
provides a highly flexible and cost effective solution for Li-ion Smart Battery applications.
The ATmega8HVA/16HVA AVR is supported with a full suite of program and system develop-
ment tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, and On-
chip Debugger.
The ATmega8HVA/16HVA is a low-power CMOS 8-bit microcontroller based on the AVR archi-
tecture. It is part of the AVR Smart Battery family that provides secure authentication, highly
accurate monitoring and autonomous protection for Lithium-ion battery cells.
