13. ultra high speed DS89C450 microcontroller The RU450 SP complements the line of MCS 51 single chip mode products from Rigel Corporation This line includes the R 51SP R 51SD and the R 420SP The RU450 SP has a mini USB port similar to those used on MP3 players and cameras The USB port communications is used for both programming the board and for communications to be performed by the downloaded application Moreover the board may be run from the USB power eliminating the need for an external power supply The RU450 SP is intended to be embedded into an end product Connections for the ports may be made through sockets headers or straight soldering into the ports The combination of the DS89C450 used with the Rigel Corporation s Reads51 software allows the microcontroller to be programmed and run in the single chip mode That is the board will run code from internal ROM using the on chip RAM Software for the boards can be written edited compiled and downloaded using Reads51 There is an industrial grade slide switch that determines if the microcontroller is in the program mode or in the run mode For OEM applications the board may be populated without the slide switch The RU450 SP is ideal for Noisy environments e g industrial automation automotive control Low cost general control as a high powered replacement for the various BASIC controllers Classroom and educational use e g robotics mechatronics projects OEM subsystems
14. w The port connections to the RU450 SP board are made through the terminals placed along the edges of the boards These terminals may be left as open holes and the application signals may be directly soldered to the terminals Alternatively the terminals may be populated by headers or sockets and the application signals may be applied through mating connectors The headers or sockets may be connected from the top or the bottom of the boards Moreover straight or right angle connectors may be used These options are intentionally left open to provide the maximum level of flexibility in the physical assembly of the final product 3 1 Power Connections The RU450 SP board uses the USB port J3 to supply the 5 Volt power needed to operate the board In addition there are several VCC 5V and GND ground terminals available on the port terminals placed along the two longer sides of the board These are convenient if a single harness for power and port signals is to be used For mobile applications you may use four 1 5V batteries in series to generate a 6V DC supply Then use one or two diodes in series to drop the voltage 3 2 Communications The board uses a serial to USB converter to connect the RS232 port of the microcontroller to the USB port J3 This port is used to program the DS89C450 The board uses the FTDI232R for serial to USB conversion FTDI232R drivers allow the PC to recognize the USB connection as a Virtual Communications Port V
