Product Overview
The RABBIT2000 is a highly integrated, high-performance 8-bit microprocessor for embedded control, communication and industrial automation. Developed by Rabbit Semiconductor (subsidiary of Digi International), it adopts optimized Z80 core with much higher instruction efficiency than traditional 8-bit MCUs, supporting a maximum clock speed of 29.4912 MHz. Equipped with dedicated MMU to break the 64KB memory limit and access up to 1MB external Flash/SRAM, it integrates 4 serial ports, battery-backed RTC, multi-mode timers and watchdog circuit. Matched with exclusive Dynamic C development environment, it enables rapid firmware development with built-in TCP/IP stack for IoT telemetry and automation control devices.
Core Advantages
Optimized High-Efficiency Core Architecture
Features an advanced, enhanced Z80 instruction execution layout that dramatically reduces clock cycles per instruction compared to standard 8-bit microcontrollers, unlocking superior compute throughput at modest clock speeds.
Comprehensive Communication Integration
Natively embeds four versatile, independent serial ports that support synchronous, asynchronous, and high-level data link control (HDLC) communication arrangements, minimizing the need for external UART controllers.
Flexible Extended Memory Space Addressing
Incorporates an on-chip hardware Memory Management Unit (MMU) that extends the traditional 8-bit 64KB limitation to smoothly address up to 1MB of code and data space in parallel flash or SRAM configurations.
Hardware and Dynamic C Software Optimization
Designed hand-in-hand with the Dynamic C development environment, allowing seamless multi-tasking, embedded TCP/IP stack execution, and real-time interactive debugging straight on the target hardware platform.

Frequently Asked Questions
Q1: Is your currently available stock of the RABBIT2000 microprocessor 100% genuine and original?
A: Yes, we guarantee that all RABBIT2000 microprocessors in our inventory are 100% brand-new, factory-original components directly traceable to Rabbit Semiconductor / Digi International. Every shipment lot undergoes precise incoming quality assessments and is packaged in original anti-static matrix trays or tape options.
Q2: What are the main benefits of using the Dynamic C compiler environment with the RABBIT2000 chip?
A: Dynamic C was co-designed directly with the Rabbit microprocessor architecture. Unlike traditional compilation loops that generate isolated binaries, Dynamic C compiles code incrementally straight to target storage memories. It natively supports specialized keyword constructs like “costatements” and “cofunctions,” simplifying real-time multi-tasking cooperative operations without needing a complex RTOS kernel.
Q3: How does an 8-bit chip like the RABBIT2000 manage to address up to 1MB of memory space?
A: Native 8-bit architectures use 16-bit address parameters, typically capping code memory layout boundaries at 64KB. The RABBIT2000 eliminates this barrier using an internal hardware Memory Management Unit (MMU). The MMU maps a large external linear flash memory into segment blocks inside standard logical windows, allowing large software applications and data blocks to coexist easily.
Q4: How can our technical hardware development group obtain the official pinout reference guide or request custom quantity quotes?
A: Please input your design parameters and required quantities into our Quick Inquiry form found directly on this web page. Our embedded component engineering and sales support desk will review your submission and reply with full data assets and custom commercial pricing tables within 24 hours.
