Datasheet

COO (Country of Origin):: TW

Microchip Technology Microcontroller

The Microchip Technology ATMEGA family type, TQFP package, surface mount, 44-pin CMOS-processor 8-bit microcontroller. It has a maximum voltage rating of 5.5V. The microcontroller operates at a maximum speed of 20MHz and features 64kb ISP flash program memory, 4kb of internal SRAM and 2kb of EEPROM. It has a real-time counter, PWM, 8-channel 10-bit A/D converter and a watchdog timer (WDT). By executing powerful instructions in a single clock cycle, it achieves throughputs approaching 1MIPS per MHz allowing the system to optimize power consumption versus processing speed.

Features and Benefits

• 131 powerful instructions - Most single-clock cycle execution
• 32 x 8 general-purpose working registers
• 32 programmable I/O lines
• External and internal interrupt sources
• Fully static operation
• On-chip 2-cycle multiplier
• Operating temperature ranges between -40°C and 85°C
• Power-on reset and programmable brown-out detection
• Six PWM channels
• Six sleep modes- Idle, ADC noise reduction, power-save, power-down, standby and extended standby
• Three USART with fractional baud rate generator, auto baud, and start-of-frame detection
• Write/Erase cycles- 10,000 flash/100,000 EEPROM

Applications

• Embedded systems
• LCD monitors and TVs
• Mobile PC docking
• PC motherboards
• Portable hub boxes
• Printers and scanners
