Variants in the product range provide the optimal combination of memory - SRAM, ROM or Flash - for each application. The External Bus Interface provides a rapid, flexible means of connecting additional memory and application-specific peripheral devices. Two key features significantly enhance the AT91's real-time performance. The Advanced Interrupt Controller substantially reduces the processor overhead in handling internal and external interrupts. The multiple Peripheral Data Controller channels allow blocks of data to be transferred directly between memory and serial peripherals without processor intervention. The peripherals are configurable, and easily programmable. The extensive range includes a full-duplex USART, an SPI operating in master or slave mode, and a Timer/Counter providing frequency measurement, event counting, interval measurement, PWM, etc. Power Management The Advanced Power Management system ensures that power consumption is kept to a minimum under all conditions of operation. The processor can be put in idle mode, and individual peripherals can be disabled if they are not used. The fully static design means that the clock can be run extremely slowly, down to zero Hertz if necessary, to reduce power consumption to an absolute minimum. AT91 Development Tools Atmel's AT91 series microcontrollers are fully supported by state-of-the art development tools including C-compilers, Assemblers, Real Time Operating Systems and software debug tools. These are provided by accredited third-party suppliers. Low-cost evaluation kits are available for the entire AT91 range. These kits provide convenient entry points for application developers.
