AVR Microcontroller

Designers considering an AVR microcontroller will appreciate the added flexibility, memory and embedded peripherals of the compact RabbitCore. More powerful and versatile than a microcontroller, the RabbitCore is designed for mounting on a user-designed motherboard, acting as the controlling microprocessor for the user’s system. Small in size but packed with powerful features, these core modules offer designers a more complete design solution than an AVR microcontroller, with integrated hardware and software and no run-time royalties. Free and unparalleled technical support is just a phone call or e-mail away.

Powered by the Rabbit 2000, the RabbitCore microprocessor core module family jumpstarts design of embedded control systems with or without integrated Ethernet connectivity. Our highly trained technical engineers are an accessible and effective resource for small to midsize OEMs.  

The Rabbit 2000 designers have years of experience using the Z180 microprocessor in embedded control products. The Rabbit shares similar architecture and a high degree of compatibility with the Z180 but features key improvements for superior performance and ease of use. The Rabbit’s fast, efficient, and C-friendly instruction set includes numerous one-byte op codes for 16-bit logical and arithmetic operations and compact instructions for 16-bit indexed loads and stores. For embedded systems, the Rabbit 2000 outruns most 16-bit and even some 32-bit processors without losing the efficiency of an 8-bit architecture.

The Rabbit 2000 microprocessor speaks to the real needs of design engineers with 30 MHz clock speed, 4 serial ports, 40 parallel I/O lines, 7 timers, battery-backable real-time clock, and watchdog timer. Design advantages include:

• Numerous on-chip peripherals and glueless interfacing to both memory and I/O, reducing system component requirements
• Onboard slave port, enabling multi-processor designs
• Multiple clock speed options through software, allowing dynamic trading of power versus speed
• Highly optimized math libraries, yielding excellent math performance with 16 x 16 multiply in 12 clocks
• Three levels of interrupt priority, allowing fast response to real-time events
• Remote cold boot for downloading new programs over serial or parallel ports with no pre-existing program
• Dynamic C development system supplying TCP/IP software stack with source code
