ATMEGA1280V-8AU, Микроконтроллер 8-бит 128Кбайт Флэш-память

The ATMEGA1280V-8AU is a high-performance, low-power 8-bit AVR RISC-based Microcontroller combines 128kB ISP flash memory, 8kB SRAM, 4kB EEPROM, 86 general purpose I/O lines, 32 general purpose working registers, real time counter, six flexible timers/counters with compare modes, PWM, 4 USARTs, byte oriented 2-wire serial interface, 16-channel 10-bit A/D converter and a JTAG interface for on-chip debugging. The device achieves a throughput of 16MIPS at 16MHz and operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves a throughput approaching 1MIPS per MHz, balancing power consumption and processing speed. The device is manufactured using the Atmel high-density nonvolatile memory technology. The on-chip ISP flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional non-volatile memory programmer, or by an on-chip boot program running on the AVR core. • Advanced RISC architecture • Power-on reset and programmable brown-out detection • Internal calibrated RC oscillator • External and internal interrupt sources • Six sleep modes - idle, ADC noise reduction, power-save, power-down, standby and extended standby • JTAG (IEEE® std. 1149.1 compliant) Interface • QTouch® library support • 135 Powerful instructions most single clock cycle execution • 32 x 8 General purpose working registers • Up to 16MIPS throughput at 16MHz • On-chip 2-cycle multiplier • Real-time counter with separate oscillator • Output compare modulator • Master/Slave SPI serial interface • Byte oriented 2-wire serial interface • Programmable watchdog timer with separate on-chip oscillator • On-chip analog comparator • Interrupt and wake-up on pin change Серия avr atmega Ядро avr Ширина шины данных 8-бит Тактовая частота 8 мгц Количество входов/выходов 86 Объем памяти программ 128 кбайт (64k x 16) Тип памяти программ flash Объем EEPROM 4k x 8 Объем RAM 8k x 8 Наличие АЦП/ЦАП ацп 16x10b Встроенные интерфейсы ebi/emi, i2c, spi, uart Встроенная периферия brown-outdetect/reset, por, pwm, wdt Напряжение питания 1.8…5.5 в Рабочая температура -40…+85c Корпус tqfp-100 (14 x 14) Вес, г 0.025 Полезная информация * МИКРОКОНТРОЛЛЕРЫ ФИРМЫ "ATMEL" СЕМЕЙСТВА AVR Microchip Technology Inc.
