1/11/2005 development software the rabbit 2000 microprocessor is ready for immediate software development. user programs are created using z-world's dynamic c ? , a c-language environment that includes a compiler, editor, and debugger. programs can be compiled and executed using the dynamic c software and a serial programming cable. no in-circuit emulator is required. programming the rabbit 2000 the rabbit 2000 is programmed using the industry-proven dynamic c? software development system-an integrated c compiler, editor , loader, and debugger created specifically fo r rabbit-based systems. developing software with dynamic c is easy. users can write , compile, and test both c and assembly code without leaving the dynamic c development environment, and no costly in-circuit emulators are required. full tcp/ip stack with source code is provided royalty free in dynamic c and with our development kits. tcp/ip support includes ppp and snmp, socket-level tcp and udp, ftp, tftp, http (w/ ssi and cgi), dhcp, smtp, pop3, and ping. rabbit 2000 features and specifications packaging 100-pin pqfp package size 24 x 18 x 3 mm operating voltage 5.5 v operating current 4 ma/mhz @ 5.5 v operating temp -40 to +80c maximum clock speed 30 mhz digital i/o 40 (arranged in five 8-bit ports) serial ports 4 cmos-compatible baud rate clock speed/32 max asynchronous address bus 20-bit data bus 8-bit timers five 8-bit and one 10-bit with 2 match registers real-time clock yes, battery backable rtc oscillator circuitry external watchdog timer/supervisor yes clock modes 1x, 2x, /2, /3, /4, /6, /8 power down modes sleepy (32 khz) auxiliary i/o bus none
