Rabbit RIO Inteligent I/O Expansion Chip The Rabbit RIO chip is an intelligent I/O processor ideally equipped for industrial automation and control. Overview Block Diagram The Rabbit RIO chip offers both I/O expansion and peripheral features that easily integrate into new or existing designs. It CPU Interface (Parallel or SPI) interfaces to any microcontroller with an available SPI or parallel port. Multiple peripheral features offer a distinct Global Control advantage for motor control applications. The Rabbit RIO Block 0 Block 7 simply takes the load off the processor, making it ideal for PWM, PPM, I/O, PWM, PPM, I/O, applications with demanding networking requirements. Quadrature Quadrature Decoder Decoder The Rabbit RIO is also ideal for machine control applications. Block 1 Block 6 PWM, PPM, I/O, PWM, PPM, I/O, I/Os are 5V tolerant, which also includes pin-pair protection Quadrature Quadrature for applications such as H-bridge drivers. Since multiple status Decoder Decoder Block 2 Block 5 bits are set from a single match register, pins are easily con- PWM, PPM, I/O, PWM, PPM, I/O, figurable for higher drive current operations. The same signal Quadrature Quadrature Decoder Decoder could be output on multiple pins for applications that require Block 3 Block 4 a higher current. It also provides push pull protection for sink PWM, PPM, I/O, PWM, PPM, I/O, and source drivers. Quadrature Quadrature Decoder Decoder Ideal Applications : Industrial control and automation, instrumentation, motion control Features/Benefits Easily interface to any CPU via an available SPI or Application Kit parallel port Instantly add up to 32 digital I/O lines 8 independent functional channels with 4 ports each This low-cost Functional channels configurable as: application kit Bi-directional I/O, PWM or PPM outputs, TRIAC includes everything signal generators, input capture, counter, you need to begin Quadrature decode peripheral development Add I/O and peripheral features to any new or existing design 299 Use multiple Rabbit RIO devices for large I/O requirements www.digi.comSpecifications Rabbit RIO Expansion Chip Features Clock Speed Up to 40 MHz Operating Voltage 3.0-3.6VDC Maximum I/O Input Voltage 5.0VDC (3.3VDC typ.)
