Version 2.1 8-Bit Micro-Controller RAiO TECHNOLOGY INC. www.raio.com.tw RA8906 Overview The RA8906 is an 8-bit downloadable micro-controller with 64K-byte embedded Flash ROM. It supports multiple timer/counter sources, versatile interrupt-handling ar chitecture and two built-in DAC’s (Digital-to-Analog Converters). It provides a complete speech interfac e and 32K-bps ADPCM solution that make this chip an excellent choice as the embedded micro-controller for educational game or toy 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 RA8906 and a PC host. The RA8906 support the ISP(In-System Programming) and ISD(In-System Debuggi ng) functions. Users can download their programs as well as data from a PC host to the embedded Flash ROM of RA8906. 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.

User application programs can be executed only in this mode. The end-us er can download the application program or data from the customer’s website through the PC interface. Bec ause the program/data was st ored in the flash so the application device of customer(such as speech toy) will operate independent that after disconnect with the PC. www. toys.com Speech Toy Down load from Internet (E nd-U sers) In tern et Speech Toy A Portable Speech Toy

Version 2.1 8-Bit Micro-Controller RAiO TECHNOLOGY INC. www.raio.com.tw RA8906 RICE-2000 (RICE for short) is a full-completed environm ent 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 env ironment at planning, desi gning 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 fram ework 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 pr ovides 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 RA8906, please refer to the user manual of RICE-2000. Application The following block diagram is the basic application circui t of RA8906. We also give three examples on the user manual of RICE-2000 to let users have more underst anding of RA8906 and the devel op environment of RICE- 2000, and then start to proceed program designing and pr oduct 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.
