DescriptionThe ATMEGA48PA-AU is designed as one kind of low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture.By executing powerful instructions in a single clock cycle,the ATmega48PA/88PA/168PA/328P achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.Also it combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle.
Features of the ATMEGA48PA-AU are:(1)high performance,low power AVR® 8-Bit microcontroller;(2)131 powerful instructions-most single clock cycle execution;(3)high endurance non-volatile memory segments;(4)speed grade:0-20 MHz @ 1.8-5.5V;(5)I/O and packages:23 programmable I/O lines;28-pin PDIP, 32-lead TQFP, 28-pad QFN/MLF and 32-pad QFN/MLF;(6)power-on reset and programmable brown-out detection;(7)internal calibrated oscillator;(8)two 8-bit timer/counters with separate prescaler and compare mode;(9)write/erase cycles:10,000 flash/100,000 EEPROM;(10)programming lock for software security.
The absolute maximum ratings of the ATMEGA48PA-AU 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 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 Ppins:200.0 mA.If you want to know more information such as the electrical characteristics about the ATMEGA48PA-AU,please download the datasheet in www.seekdatasheet.com or www.chinaicmart.com.
