ATMEGA406 Series

The high-performance, low-power Microchip 8-bit AVR® Battery Management microcontroller combining 40 KB ISP Flash memory, 512B EEPROM, 2 KB 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 a throughput of one MIPS at 1 MHz and operates between 4-25 volts, balancing power consumption and processing speed.
