Version 1.0 Overview
8-Bit Micro-Controller
RA8917
RA8917 is an 8-bit downloadable micro-controller. Up to 22MHz system clock makes it a perfect choice for high-end device. It contains a 16x16 Multiplier and Accumulator (MAC), which not only greatly reduce programmer's effort, but also shorten development time. RA8917 is embedded 4-channel 12-Bit ADC that can vary your application fields in analog detection, such as temperature, pressure, humidity, etc. Moreover, matched with LCM (LCD Module), 12-bit ADC can be perfectly used in Touch Panel function. RA8917 is suitable for any downloadable device no matter used by end-users for voice/data download, or used by programmers for S/W program updated. The built-in 8K-byte ROM supports the on-chip RAiO ICE Monitor program, ISP(In-System Programming) and ISD(In-System Debugging), which controls the UART and enables the RS232 connection between the RA8917 and a PC host. Besides that, IrDA application is also allowed to give the device multiple attractive characteristics. In short, RA8917 supports embedded 4K-byte SRAM, three I/O ports, LCD interface, built in PLL / RC Oscillator, LVD, multiple timer/counter sources, versatile interrupt-handling architecture, built-in one DAC (Digital-to-Analog Converters), 16x16 Multiplier and Accumulator (MAC), 4-channel 12-Bit ADC and support three EDO DRAM (Extended Data Out) interface configuration: one 4Mx4bit chip, two 4Mx4 chips and one 8Mx8 chip.

The RA8917 support the ISP (In-System Programming) and ISD (In-System Debugging) functions for customer to develop their system. Users can download their programs as well as data from a PC host to the external Flash ROM. -ISP/ISD Mode is entered when the MONITOR# pin having been pulled down to ground voltage level. The on-chip 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.

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.

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 8-bit 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 are 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 RA8917, please refer to the user manual of RICE-2000.

The following Block diagram is the basic application circuit of RA8917. We also give three examples on the user manual of RICE-2000 to let users have more understanding of RA8917 and the develop environment of RICE-2000, 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.
