Rabbit Semiconductor is a fabless semiconductor company specializing
in microprocessors and innovative development tools for the embedded controls
industry. The Rabbit 3000 is a high-performance, 8-bit microprocessor
distinguished by its C-friendly instruction set and fast number-crunching
ability. Numerous on-chip peripherals and glueless interfacing to both
memory and I/O reduces system component requirements and saves OEMs significant
design time and production costs.
For embedded systems, the Rabbit 2000 and Rabbit 3000 outruns most 16-bit
and even some 32-bit processors without losing the efficiency of an 8-bit
architecture. In its first year on the market, an independent survey of
OEM designers showed that more engineers were considering the Rabbit 2000
over such established chips as the Hitachi H8, Dallas 80xx/80Cxx, and
Zilog Z8/80/180.
Rabbit 2000 designers have years of experience using Z180 and HD64180
microprocessors in embedded control products. While it runs three times
faster, the Rabbit shares a similar architecture and a high degree of
compatibility with the Z180 and HD64180, but with key improvements for
superior performance and ease of use. Programmers familiar with the HD64180
or Z180 will be completely at ease with the Rabbit 2000 or Rabbit 3000.
The Rabbit 2000 and 3000 is ideal for systems requiring a low-cost microprocessor
with extensive software capability. 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. Software development is accomplished by connecting
a simple interface cable from a PC serial port to the Rabbit-based target
system.
The Rabbit 2000 and 3000 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
