The Microchip AVR core 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. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The ATmega8A provides the following features: 8K bytes of In-System Programmable Flash with ReadWhile- Write capabilities, 512 bytes of EEPROM, 1K byte of SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, internal and external interrupts, a serial programmable USART, one byte oriented Two-wire Serial Interface, a 6- channel ADC (eight channels in TQFP and QFN/MLF packages) with 10-bit accuracy, a programmable Watchdog Timer with Internal Oscillator, an SPI serial port, and five software selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, one SPI port, and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next Interrupt or Hardware Reset. In Power-save mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping. Microchip offers the QTouch library for embedding capacitive touch buttons, sliders and wheels functionality into AVR microcontrollers. The patented charge-transfer signal acquisition offers robust sensing and includes fully debounced reporting of touch keys and includes Adjacent Key Suppression (AKS ) technology for unambiguous detection of key events. The easy-to-use QTouch Composer allows you to explore, develop and debug your own touch applications.Key FeaturesHigh-performance, Low-power Atmel AVR 8-bit MicrocontrollerAdvanced RISC Architecture130 Powerful Instructions - Most Single-clock Cycle Execution32 x 8 General Purpose Working RegistersFully Static OperationUp to 16MIPS Throughput at 16MHzOn-chip 2-cycle MultiplierHigh Endurance Non-volatile Memory segments8KBytes of In-System Self-programmable Flash program memory512Bytes EEPROM1KByte Internal SRAMWrite/Erase Cycles: 10,000 Flash/100,000 EEPROMData retention: 20 years at 85°C/100 years at 25°C(1)Optional Boot Code Section with Independent Lock BitsIn-System Programming by On-chip Boot ProgramTrue Read-While-Write OperationProgramming Lock for Software SecurityAtmel QTouch® library supportCapacitive touch buttons, sliders and wheelsAtmel QTouch and QMatrix acquisitionUp to 64 sense channelsPeripheral FeaturesTwo 8-bit Timer/Counters with Separate Prescaler, one Compare ModeOne 16-bit Timer/Counter with Separate Prescaler, Compare Mode, and Capture ModeReal Time Counter with Separate OscillatorThree PWM Channels8-channel ADC in TQFP and QFN/MLF packageEight Channels 10-bit Accuracy6-channel ADC in PDIP packageSix Channels 10-bit AccuracyByte-oriented Two-wire Serial InterfaceProgrammable Serial USARTMaster/Slave SPI Serial InterfaceProgrammable Watchdog Timer with Separate On-chip OscillatorOn-chip Analog ComparatorSpecial Microcontroller FeaturesPower-on Reset and Programmable Brown-out DetectionInternal Calibrated RC OscillatorExternal and Internal Interrupt SourcesFive Sleep Modes: Idle, ADC Noise Reduction, Power-save, Power-down, and StandbyI/O and Packages23 Programmable I/O Lines28-lead PDIP, 32-lead TQFP, and 32-pad QFN/MLFOperating Voltages2.7 - 5.5VSpeed Grades0 - 16MHzPower Consumption at 4MHz, 3V, 25°CActive: 3.6mAIdle Mode: 1.0mAPower-down Mode: 0.5μACore ProcessorAVRCore Size8-BitSpeed16MHzConnectivityI²C, SPI, UART/USARTPeripheralsBrown-out Detect/Reset, POR, PWM, WDTNumber of I/O23Program Memory Size8KB (4K x 16)Program Memory TypeFLASHEEPROM Size512 x 8RAM Size1K x 8Voltage - Supply (Vcc/Vdd)2.7 V ~ 5.5 VData ConvertersA/D 6x10bOscillator TypeInternalOperating Temperature-40°C ~ 85°C (TA)Package / Case28-DIP (0.300", 7.62mm)Supplier Device Package28-PDIPWhy choosing usLocated in Shenzhen, the electronic market center of China.100% guarantee components quality: Genuine Original.Sufficient stock on your urgent demand.Sophisticated colleagues help you solve problems to reduce your risk with on-demand manufacturingFaster shipment: In stock components can ship the same day .24 Hours service
