RA8906
Version 2.1
8-Bit Micro-Controller
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 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 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 Debugging) 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.
