INTELIGENT I/O EXPANSION CHIP RABBIT RIO® The Rabbit RIO chip is an intelligent I/O processor ideally equipped for industrial automation and control The Rabbit RIO chip offers both I/O expansion and peripheral features that easily integrate into new or existing designs. It interfaces to any microcontroller with an available SPI or parallel port. Multiple peripheral features offer a distinct advantage for motor control applications. The Rabbit RIO simply takes the load off the processor, making it ideal for applications with demanding networking requirements. configurable for higher drive current operations. The same signal could be output on multiple pins for applications that require a higher current. It also provides push pull protection for sink and source drivers. The Rabbit RIO is also ideal for machine control applications. I/Os are 5V tolerant, which also includes pin-pair protection for applications such as H-bridge drivers. Since multiple status bits are set from a single match register, pins are easily BENEFITS APPLICATION EXAMPLE – Easily interface to any CPU via an available SPI or parallel port CPU INTERFACE (PARALLEL OR SPI) – Instantly add up to 32 digital I/O lines – 8 independent functional channels with 4 ports each – Functional channels configurable as: Bi-directional I/O, PWM or PPM outputs, TRIAC signal generators, input capture, counter, Quadrature decode peripheral – Add I/O and peripheral features to any new or existing design – Use multiple Rabbit RIO devices for large I/O requirements RELATED PRODUCTS Rabbit® SBC BL2100 Series Rabbit® SBC BL4S100 Series Rabbit® SBC BL4S200 Series RabbitCore® RCM3000 Series Dynamic C® GLOBAL CONTROL Block 0 Block 7 PWM, PPM, I/O, Quadrature Decoder PWM, PPM, I/O, Quadrature Decoder Block 1 Block 6 PWM, PPM, I/O, Quadrature Decoder PWM, PPM, I/O, Quadrature Decoder Block 2 Block 5 PWM, PPM, I/O, Quadrature Decoder PWM, PPM, I/O, Quadrature Decoder Block 3 Block 4 PWM, PPM, I/O, Quadrature Decoder PWM, PPM, I/O, Quadrature Decoder Rabbit RIO® Expansion Chip SPECIFICATIONS FEATURES CLOCK SPEED Up to 40 MHz OPERATING VOLTAGE 3.0-3.6VDC MAXIMUM I/O INPUT VOLTAGE 5.0VDC (3.3VDC typ.)
