INTELIGENT I/O EXPANSION CHIP RABBIT 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. 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 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. BENEFITS Easily interface to any CPU via an available SPI or parallel port 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 SBC BL2100 Series SBC BL4S100 Series SBC BL4S200 Series RCM3000 Series Dynamic APPLICATION EXAMPLE CPU INTERFACE PARALLEL OR SPI GLOBAL CONTROL Block 0 PWM, PPM, I/O, Quadrature Decoder Block 1 PWM, PPM, I/O, Quadrature Decoder Block 2 PWM, PPM, I/O, Quadrature Decoder Block 3 PWM, PPM, I/O, Quadrature Decoder Block 7 PWM, PPM, I/O, Quadrature Decoder Block 6 PWM, PPM, I/O, Quadrature Decoder Block 5 PWM, PPM, I/O, Quadrature Decoder Block 4 PWM, PPM, I/O, Quadrature Decoder SPECIFICATIONS FEATURES CLOCK SPEED OPERATING VOLTAGE MAXIMUM I/O INPUT VOLTAGE CORE CURRENT I/O RING OUTPUT DRIVE CPU INTERFACES FIXED DIGITAL INPUTS CONFIGURABLE I/O PACKAGE TYPE Rabbit Expansion Chip Up to 40 MHz 3.0-3.6VDC

RABBIT

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.

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
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.

BENEFITS Easily interface to any CPU via an available SPI or
parallel port 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
