RABBIT2000

The Rabbit 2000 microprocessor, developed by Rabbit Semiconductor, is designed for use in small and medium-scale controllers. It shares a similar architecture and high compatibility with Z80, Z180, and HD64180 microprocessors but offers significant improvements.

Key features include a 100-pin PQFP package, an operating voltage range of 2.7V to 5V, and a clock speed of up to 30 MHz. The microprocessor supports 1-megabyte of code space, allowing for C programs with over 50,000 lines of code. Its Z80-derived instruction set is C-friendly, optimized for common C operations, and enables fast instruction execution.

Hardware and software interfaces are designed for ease of use, simplifying development without the need for in-circuit emulators. Software development is facilitated by connecting a simple interface cable from a PC serial port to the target system. The Rabbit 2000 boasts outstanding computation speed for an 8-bit bus, maximizing memory bandwidth utilization.

Specifications are provided for both industrial (-40°C to +85°C) and commercial (0°C to 70°C) temperature ranges. The design allows direct connection of up to six static memory chips without glue logic, and larger memory configurations are possible using parallel I/O lines as high-order address lines. The Rabbit 2000 can run at 24 MHz with no wait states when using memory with a 70 ns access time.
