Version 1.5

8-Bit Micro-Controller

Overview

RA8911 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. RA8911 is embedded 4-channel 10-Bit ADC that

can vary your application fields in analog detection, such as temperature, pressure, humidity, etc. Moreover,

matched with LCM (LCD Module), 10-bit ADC can be perfectly used in Touch Panel function.

RA8911 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 4K-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 RA8911 and a PC host. Besides that, IrDA application is

also allowed to give the device multiple attractive characteristics.

In short, RA8911 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) and support 4-channel 10-Bit ADC.
