ATMEGA649V

The ATMEGA649V is designed as one kind of low-power CMOS 8-bit microcontroller device that achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. And this device based on the AVR enhanced RISC architecture. Also it is manufactured using Atmel's high-density nonvolatile memory technology.

Features of the ATMEGA649V are:(1)Power-on Reset and Programmable Brown-out Detection; (2)Internal Calibrated Oscillator; (3)External and Internal Interrupt Sources; (4)Five Sleep Modes: Idle, ADC Noise Reduction, Power-save, Power-down, and Standby; (5)On-Chip 2-cycle Multiplier; (6)Two 8-bit Timer/Counters with Separate Prescaler and Compare Mode; (7)Four 16-bit Timer/Counter with Separate Prescaler, Compare- and Capture Mode; (8)64-lead TQFP, 64-pad QFN/MLF, and 100-lead TQFP; (9)53/68 Programmable I/O Lines; (10)Master/Slave SPI Serial Interface; (11)Universal Serial Interface with Start Condition Detector; (12)Temperature range: -40°C to 85°C Industrial; (13)On-chip Analog Comparator; (14)Interrupt and Wake-up on Pin Change.etc.

The absolute maximum ratings of the ATMEGA649V can be summarized as:(1)Operating Temperature: -55°C to +125°C;(2)Storage Temperature: -65°C to +150°C;(3)Voltage on any Pin except RESET with respect to Ground: -0.5V to VCC+0.5V;(4)Voltage on RESET with respect to Ground: -0.5V to +13.0V;(5)Maximum Operating Voltage: 6.0 V;(6)DC Current per I/O Pin: 40.0 mA;(7)DC Current VCC and GND Pins: 200.0 mA.
