Rabbit Microcontrollers

Rabbit SemiconductorThe Rabbit microcontrollers from Rabbit Semiconductor are a descendant of the venerable Z80 family of microcontrollers. The Rabbit 2000 offers high performance, 8-bit memory interface, 1 megabit of code space, four serial ports, up to 40 I/O lines, seven timers, a built-in RTC (real time clock), and support for in-system programming and TCP/IP networking. Low-cost development tools are available.

On the negative side of the ledger, the "Dynamic C" compiler included with the development kits is best suited to small projects. Few third-party tools are available. As for the chip itself, the only minuses are lack of a single-chip version, no on-board EEPROM, and no on-board ADCs.

The newer Rabbit processors offers faster speeds, lower EMI, more I/O, and more serial ports.
