Микроконтроллеры ARM AT91SAM9R64-CU

Микроконтроллер ARM , SAM9 Family AT91SAM9X Series Microcontrollers, ARM9, 32бита, 240 МГц, 32 КБ

The AT91SAM9R64-CU is a 32-bit Embedded Microprocessor Unit based on the integration of an ARM926EJ-S processor with a large fast SRAM and a wide range of peripherals. The AT91SAM9R64 embeds one USB device high speed controller, one AC97 controller, a 2-channel DMA controller, four USARTs, two SSCs, one SPI, two TWIs, three timer counter channels, a 4-channel PWM generator, one multimedia card interface and a 6-channel Analog-to-digital Converter (ADC) that also provides resistive touch screen management. The AT91SAM9R64 is architectured on a 6-layer bus matrix. It also features an external bus interface capable of interfacing with a wide range of memory and peripheral devices.
