Overview The ATmega16HVB/32HVB is a monitoring and protection circuit for 3 and 4-cell Li-ion applications with focus on highest safety including safe 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 ATmega16HVB/32HVB a key component in any system focusing on high security, battery protection, high system utilization and low cost. Figure 2-1.

The chip is specifically designed to provide safety for the battery cells in case of pin shorting, loss of power (either caused by battery pack short or VCC short), illegal charger connection or software runaway. This makes ATmega16HVB/32HVB the ideal 1-chip solution for applications with focus on high safety. The ATmega16HVB/32HVB features an integrated voltage regulator that operates at a wide range of input voltages, 4 - 25 volts. This voltage is regulated to a constant supply voltage of nominally 3.3 volts for the integrated logic and analog functions. The regulator capabilities, com- 5 8042B–AVR–06/10 ATmega16HVB/32HVB bined with an extremely low power consumption in the power saving modes, greatly enhances the cell energy utilization compared to existing solutions. The chip utilizes Atmel's patented Deep Under-voltage Recovery (DUVR) mode that supports pre-charging of deeply discharged battery cells without using a separate Pre-charge FET. DUVR mode cannot be used in 2-cell applications. Optionally, Pre-charge FETs are supported for integration into many existing battery charging schemes. The battery protection monitors the charge and discharge current to detect illegal conditions and protect the battery from these when required. A 12-bit Voltage ADC allows software to monitor each cell voltage individually with high accuracy. The ADC also provides one internal input channel to measure on-chip temperature and two input channels intended for external thermistors. An 18-bit ADC optimized for Coulomb Counting accumulates charge and discharge currents and reports accumulated current with high resolution and accuracy. It can also be used to provide instantaneous current measurements with 13 bit resolution. Integrated Cell Balancing FETs allow cell balancing algorithms to be implemented in software. The MCU provides the following features: 16K/32K bytes of In-System Programmable Flash with Read-While-Write capabilities, 512/1K bytes EEPROM, 1K/2K bytes SRAM. 32 general purpose working registers, 12 general purpose I/O lines, 5 general purpose high voltage open drain I/O lines, one general purpose super high voltage open drain output, debugWIRE for On-chip debugging and SPI for In-system Programming, a SM-Bus compliant TWI module, 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 resolution Sigma Delta ADC for Coulomb Counting and instantaneous current measurements, integrated cell balancing FETs, Additional Secure Authentication Features, an autonomous Battery Protection module, a programmable Watchdog Timer with internal Oscillator, 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 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 conventional CISC microcontrollers. The device is manufactured using Atmel’s high voltage high density non-volatile memory technology. 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 Onchip Boot program running on the AVR core. The Boot program can use any interface to download the application program in the Application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated, providing true ReadWhile-Write operation. By combining an 8-bit RISC CPU with In-System Self-ProgrammableFlash and highly accurate analog front-end in a monolithic chip. The Atmel ATmega16HVB/32HVB is a powerful microcontroller that provides a highly flexible and cost effective solution. It is part of the AVR Battery Management family that provides secure authentication, highly accurate monitoring and autonomous protection for Lithium-ion battery cells. The ATmega16HVB/32HVB AVR is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, and Onchip Debugger. 6 8042B–AVR–06/10 ATmega16HVB/32HVB 2.1 Comparison Between ATmega16HVB and ATmega32HVB The ATmega16HVB and ATmega32HVB differ only in memory size for Flash, EEPROM and internal SRAM.

About Code Examples This documentation contains simple code examples that briefly show how to use various parts of the device. These code examples assume that the part specific header file is included before compilation. Be aware that not all C compiler vendors include bit definitions in the header files and interrupt handling in C is compiler dependent. Please confirm with the C compiler documentation for more details. For I/O registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI” instructions must be replaced with instructions that allow access to extended I/O. Typically “LDS” and “STS” combined with “SBRS”, “SBRC”, “SBR”, and “CBR”. 6. Data Retention Reliability Qualification results show that the projected data retention failure rate is much less than 1 PPM over 20 years at 85°C or 100 years at 25°C. 8 8042B–AVR–06/10 ATmega16HVB/32HVB 7.

PINA3 PINA2 PINA1 PINA0 78 Notes: 1. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses should never be written. 2. I/O registers within the address range $00 - $1F are directly bit-accessible using the SBI and CBI instructions. In these registers, the value of single bits can be checked by using the SBIS and SBIC instructions. 3. Some of the status flags are cleared by writing a logical one to them. Note that the CBI and SBI instructions will operate on all bits in the I/O register, writing a one back into any flag read as set, thus clearing the flag. The CBI and SBI instructions work with registers 0x00 to 0x1F only. 4. When using the I/O specific commands IN and OUT, the I/O addresses $00 - $3F must be used. When addressing I/O registers as data space using LD and ST instructions, $20 must be added to these addresses. The ATmega16HVB/32HVB is a complex microcontroller with more peripheral units than can be supported within the 64 location reserved in Opcode for the IN and OUT instructions. For the Extended I/O space from $60 - $FF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used. 12 8042B–AVR–06/10 ATmega16HVB/32HVB 8.
