Copyright RAiO Technology Inc. 2002, 2003 RAiO TECHNOLOGYINC. 1/9 www.raio.com.tw Revision 1.4 Overview RA8900 8-Bit Micro-Controller The RA8900 is an 8-bit downloadable micro-controller. It supports multiple timer/counter sources, versatile interrupt-handling architecture and two built-in DAC's (Digital-to-Analog Converters). It provides a complete speech interface and 32K-bps ADPCM solution that make this chip an excellent choice as the embedded microcontroller for educational speech products. The built-in 4K-bytes ROM support the on-chip RAiO ICE Monitor program which controls the UART and enables the RS232 connection between the RA8900 and a PC host. The RA8900 support the ISP(In-System Programming) and ISD(In-System Debugging) functions. Users can download their programs as well as data from a PC host to the external Flash ROM. RAiO also support a windows based ICE driver for customers to very easy programming & debugging their program. Using RS232 connection between a speech toy to a PC host running RAiO's download utility program, toy makers are able to implement the Internet Game/Speech download features easily and give the toys multiple attractive characteristics.

The onchip Monitor program together with RAiO's ICE(RICE-2000) Utility Program running on a PC will be executed to support ICE debugging and ISP download of user programs from the PC Host. RAiO TECHNOLOGYINC. 7/9 www.raio.com.tw Revision 1.4 RAiO ICE ISP Development RA8900 8-Bit Micro-Controller Speech Toy Develop Program from ISP Mode (Customers) -User Mode is entered when the MONITOR# pin has been pulled up to logic high voltage level. User application programs can be executed only in this mode. The end-user can download the application program or data from the customer's website through the PC interface. Because the program/data was stored in the flash so the application device of customer(such as speech toy) will operate independent that after disconnect with the PC. Internet www. toys.com Speech Toy Speech Toy Down load from Internet (End-Users) A Portable Speech Toy RICE-2000 (RICE for short) is a full-completed environment developed by RAiO especially for RA89XX series. The major reason for developing RICE is give fully convenience to program designers who are using RA89XX IC, and let them enjoy consistent and friendly design environment at planning, designing and debugging. In RICE environment, it saves a great deal of developing time by not only providing Editor for users to do direct coding, but also providing many Hot-Key functions for users to do direct compiling, linking, and downloading. Since RA89XX series carry e-MCU micro-processor and a framework of ISP(In-System-Programming), ISD(In-System Debugging), then this simple and reliable environment of RICE can let program designers to proceed design and debug in Real Chip. Moreover, the mass-production ICs is ready for clients to do planning and designing directly without diverse traits happened between developing time and mass production period. In the meanwhile, in order to support integrated speech interface, RICE provides a solution of 32K-bps ADPCM for programmers to easily combine programs and speech files. If you want to have more information and program design skills of RA8900, please refer to the user manual of RICE-2000. Application The following Block diagram is the basic application circuit of RA8900. We also give three examples on the user manual of RICE-2000 to let users have more understanding of RA8900 and the develop environment of RICE2000, and then start to proceed program designing and product developing. The examples have one simple I/O control and two speech samples. Please refer to the user manual of RICE-2000 if you needed.
