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 configurable for higher drive current operations. The same features that easily integrate into new or existing designs. It signal could be output on multiple pins for applications that interfaces to any microcontroller with an available SPI or require a higher current. It also provides push pull protection parallel port. Multiple peripheral features offer a distinct for sink and source drivers. advantage for motor control applications. The Rabbit RIO simply takes the load off the processor, making it ideal for applications with demanding networking requirements. 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 GLOBAL CONTROL Functional channels configurable as: Bi-directional I/O, PWM or PPM outputs, TRIAC Block 0 Block 7 signal generators, input capture, counter, PWM, PPM, I/O, PWM, PPM, I/O, Quadrature decode peripheral Quadrature Decoder Quadrature Decoder Add I/O and peripheral features to any new or Block 1 Block 6 existing design PWM, PPM, I/O, PWM, PPM, I/O, Quadrature Decoder Quadrature Decoder Use multiple Rabbit RIO devices for large I/O requirements Block 2 Block 5 PWM, PPM, I/O, PWM, PPM, I/O, Quadrature Decoder Quadrature Decoder RELATED PRODUCTS Block 3 Block 4 PWM, PPM, I/O, PWM, PPM, I/O, Quadrature Decoder Quadrature Decoder Rabbit SBC Rabbit SBC Rabbit SBC RabbitCore Dynamic C BL2100 BL4S100 BL4S200 RCM3000 Series Series Series SeriesSPECIFICATIONS Rabbit RIO Expansion Chip FEATURES CLOCK SPEED Up to 40 MHz 3.0-3.6VDC OPERATING VOLTAGE 5.0VDC (3.3VDC typ.)
