The high-performance, low-power Atmel 8-bit AVR Battery Management microcontroller combining 40KB ISP flash memory, 512B EEPROM, 2KB SRAM, 32 general purpose working registers, 18 general purpose I/O lines, 11 high-voltage I/O lines, JTAG interface for on-chip debugging, two flexible timer/counters with PWM and compare modes, one wake-up Timer, an SM-Bus compliant TWI module, internal and external interrupts, 12-bit Sigma Delta ADC for voltage and temperature measurements, high resolution Sigma Delta ADC for coulomb counting and instantaneous current measurements, programmable watchdog timer with internal oscillator, and four software selectable power saving modes.
By executing powerful instructions in a single clock cycle, the device achieves throughput of 1 MIPS at 1MHz and operates between 4-25 volts, balancing power consumption and processing speed.
