ATMEGA328P-PU Microchip AVR Microcontroller 8bit 20MHz 32 kB Flash DIP-28 (Made in Thailand)

From the shop's description

ATMEGA328P-PU Microchip AVR Microcontroller 8bit 20MHz 32 kB Flash DIP-28 The ATmega48A/PA/88A/PA/168A/PA/328/P is a low power, CMOS 8-bit microcontrollers based on the AVR enhanced RISC architecture. By executing instructions in a single clock cycle, the devices achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed. Features High Performance, Low Power AVR 8-Bit Microcontroller Family Advanced RISC Architecture 131 Powerful Instructions – Most Single Clock Cycle Execution 32 x 8 General Purpose Working Registers Up to 20 MIPS Throughput at 20MHz On-chip 2-cycle Multiplier High Endurance Non-volatile Memory Segments 4/8/16/32KBytes of In-System Self-Programmable Flash program memory 256/512/512/1KBytes EEPROM 512/1K/1K/2KBytes Internal SRAM Write/Erase Cycles: 10,000 Flash/100,000 EEPROM Data retention: 20 years at 85°C/100 years at 25°C(1) Optional Boot Code Section with Independent Lock Bits In-System Programming by On-chip Boot Program True Read-While-Write Operation Programming Lock for Software Security QTouch® library support Capacitive touch buttons, sliders and wheels QTouch and QMatrix™ acquisition Up to 64 sense channels Peripheral Features Two 8-bit Timer/Counters with Separate Prescaler and Compare Mode One 16-bit Timer/Counter with Separate Prescaler, Compare Mode, and Capture Mode Real Time Counter with Separate Oscillator Six PWM Channels 8-channel 10-bit ADC in TQFP and QFN/MLF package Temperature Measurement Channel 10-bit ADC in PDIP Package Temperature Measurement Programmable Serial USART Master/Slave SPI Serial Interface Byte-oriented 2-wire Serial Interface (Philips I2C compatible) Programmable Watchdog Timer with Separate On-chip Oscillator On-chip Analog Comparator Interrupt and Wake-up on Pin Change Special Microcontroller Features Power-on Reset and Programmable Brown-out Detection Internal Calibrated Oscillator External and Internal Interrupt Sources Six Sleep Modes: Idle, ADC Noise Reduction, Power-save, Power-down, Standby, and Extended Standby I/O and Packages 23 Programmable I/O Lines 28-pin PDIP, 32-lead TQFP, 28-pad QFN/MLF and 32-pad QFN/MLF Operating Voltage: 1.8 – 5.5V Temperature Range: -40°C to 85°C Speed Grade: 0 – 4MHz@1.8 – 5.5V, 0 – 10MHz@2.7 – 5.5.V, 0 – 20MHz @ 4.5 – 5.5V Power Consumption at 1MHz 1.8V, 25°C Active Mode: 0.2mA Power-down Mode: 0.1µA Power-save Mode: 0.75µA (Including 32kHz RTC) Pin Configuration Specifications Manufacturer: Microchip Brand: Microchip Technology Product Category: 8-bit Microcontrollers Datasheet ATMEGA328P-PU Microcontroller Core: AVR Program Memory Type: Flash Program Memory Size: 32 kB Data RAM Size: 2 kB Package/Case: PDIP-28 Maximum Clock Frequency: 20 MHz ADC Resolution: 10 bit Number of I/Os: 23 I/O Supply Voltage – Min: 1.8 V Supply Voltage – Max: 5.5 V Mounting Style: Through Hole Data Bus Width: 8 bit Minimum Operating Temperature: – 40 C Maximum Operating Temperature: + 85 C Data RAM Type: SRAM Data ROM Size: 1 kB Data ROM Type: EEPROM Interface Type: I2C, SPI, USART Number of ADC Channels: 6 Channel Number of Timers/Counters: 3 Timer Processor Series: megaAVR Applications Arduino Development.
