Description

The ATMEGA32-16AU is one member of the ATMEGA32 series.The ATmega32 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega32 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Features of the ATMEGA32-16AU are:(1)131 powerful instructions most single-clock cycle execution; (2)32 x 8 general purpose working registers; (3)fully static operation; (4)up to 16 MIPS throughput at 16 MHz; (5)on-chip 2-cycle multiplier; (6)byte-oriented two-wire serial interface; (7)programmable serial USART; (8)master/slave spi serial interface; (9)programmable watchdog timer with separate on-chip oscillator; (10)on-chip analog comparator; (11)power-on reset and programmable brown-out detection; (12)internal calibrated RC oscillator; (13)external and internal interrupt sources; (14)six sleep modes: idle, ADC noise reduction, power-save, power-down, standby and extended standby.

The absolute maximum ratings of the ATMEGA32-16AU can be summarized as:(1)operating temperature:-55 to 125;(2))storage temperature:-65 to 150;(3)voltage on any pin except RESET with respect to ground:-0.5 to Vcc+0.5V;(4)maximum operating voltage:6.0V;(5)DC current per I/O pin:40.0 mA.Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.Special care must be taken if the user allows the Boot Loader section to be updated by leaving Boot Lock bit11 unprogrammed. An accidental write to the Boot Loader itself can corrupt the entire Boot Loader, and further software updates might be impossible. If it is not necessary to change the Boot Loader software itself, it is recommended to program the Boot Lock bit11 to protect the Boot Loader software from any internal software changes.
