Product Description

Atmel/Microchip ATmega328P ATmega328P-PU, ATmega328P-PN 8-bit ATmega328P-AVR Microcontrollers
IntroductionThe Atmel® picoPower® ATmega328/P is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega328/P achieves throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.FeatureHigh Performance, Low Power Atmel®AVR® 8-Bit Microcontroller Family• Advanced RISC Architecture- 131 Powerful Instructions- Most Single Clock Cycle Execution- 32 x 8 General Purpose Working Registers- Fully Static Operation- Up to 20 MIPS Throughput at 20MHz- On-chip 2-cycle Multiplier• High Endurance Non-volatile Memory Segments- 32KBytes of In-System Self-Programmable Flash program Memory- 1KBytes EEPROM- 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• Atmel® 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- 6-channel 10-bit ADC in PDIP Package• Temperature Measurement- Two Master/Slave SPI Serial Interface- One Programmable Serial USART- One Byte-oriented 2-wire Serial Interface (Philips I2C compatible)- Programmable Watchdog Timer with Separate On-chip Oscillator- One 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, andExtended 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 105°C• Speed Grade:- 0 - 4MHz @ 1.8 - 5.5V- 0 - 10MHz @ 2.7 - 5.5V- 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)DescriptionThe Atmel 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 a 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 ATmega328/P provides the following features: 32Kbytes of In-System Programmable Flash with Read-While-Write capabilities, 1Kbytes EEPROM, 2Kbytes SRAM, 23 general purpose I/O lines, 32 general purpose working registers, Real Time Counter (RTC), three flexible Timer/Counters with compare modes and PWM, 1 serial programmable USARTs , 1 byte-oriented 2-wire Serial Interface (I2C), a 6- channel 10-bit ADC (8 channels in TQFP and QFN/MLF packages) , a programmable Watchdog Timer with internal Oscillator, an SPI serial port, and six software selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, 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. The ADC Noise Reduction mode stops the CPU and all I/O modules except asynchronous timer and ADC to minimize switching noise during ADC conversions. In Standby mode, the crystal/resonator oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low power consumption. In Extended Standby mode, both the main oscillator and the asynchronous timer continue to run.Atmel 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 Suite toolchain allows you to explore, develop and debug your own touch applications.The device is manufactured using Atmel's high density non-volatile memory technology. The On-chip ISP Flash allows the program memory to be reprogrammed In-System through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core.The Boot program can use any interface to download the application program in the Application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated, providing true Read-While-Write operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the Atmel ATmega328/P is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.The ATmega328/P is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators, and Evaluation kits.ATMEGA328P-PU
