SC9308
AUDIO SYSTEM CONTROL MCU WITH ANALOG RADIO FUNCTION
DESCRIPTION
SC9308 is a SOC based on Silan’s 8-bit MCU SC65X for analog radio
DFR control with low voltage low power consumption. Built-in LCD
driver which can drive max. 4X14 segments display, 31 configurable
I/O ports and three 8-bit counters, two of which can be combined to
achieve 16 timing length; Built-in real time clock ensures the system
uninterrupted counting when it is in sleep state; 11 interrupt sources,
including four external interrupts, enabling the system to respond
quickly to internal or external events. Multi-mode optional serial
communication circuits greatly increase the system's scalability. Built-in
3.2MHz RC oscillator with external 75KHz oscillator can achieve the
perfect balance between power and speed. In high speed application, it
can extend external high frequency crystal through PC.4/5 pin,
maximum up to 6MHz.

SC9308
Real time Clock (RTC)
RTC module can provide powerful timing function. When it starts, it will work separately from CPU. It can provide
minute, hour and year/month/day, etc. in BCD formats. Minute, hour, week, day alarm can be set, and the alarm
function can be triggered by interrupt or inquiring the alarm flag by software. At the same time, it will generate
0.5s real time clock signal, which can trigger interrupt. This interrupt shares one channel with alarm interrupt. It is
used together with INTCON register. At the same time, it provides 4 BUZ signals to driver the buzzer.
Timer T0/T1/T2
SC9308 includes three 8-bit timers Timer0, Timer1 and Timer2. Where, T0 and T1 timers can be together used
as 16-bit timer. When T0 or T1 are used separately, their functions are as follows:
¾ 8-bit programmable timing, generate interrupt after setting the time interval
¾ Arbitrary frequency output
¾ External clock frequency division
T0/T1/T2 has one control register and one pre-assignment register.
T2 timer has input capture except for the similar functions as T0/T1. capture signal input are all diplex with PA6
pin.
UART
SC9308 has built-in full duplex async communication interface. Communication port with three modes: 8bit
variable baud rate, 9bit fixed baud rate or variable baud rate communication.
¾ Tx pin diplex with PB4, RX pin diplex with PB5
¾ Baud rate presetting register can adjust baud rate freely
¾ Transmitting and receiving interrupt cooperation dual buffer can make sure the high speed
communication stable and reduce the CPU load.
8-bit ADC
8-bit AD converter is mainly used for keyboard scan or electronic volume display. It has 4 input channels
www.DataSh(PeeCt40U/1.c/4o/m5). Select a channel and input switch level by program and the result is stored in an 8-bit register.
Conversion clock has 4 selectable clock sources. Input internal reference voltage through channel 6 of ADC to
detect the battery voltage(together with internal standard voltage). PC4/5 can also be used to extend high
frequency oscillator pin, if it is not connected to oscillator, do not effect ADC input channel. Adopt 75KHz clock,
one AD conversion needs 12 clock cycles, and the typical conversion time of ADC is 160μs.
Frequency counting module
This module mainly includes local oscillator signal amplifier and gate control counting two sections. FM or AM
local oscillator signal is counted by a 16-bit counter after amplified. This counter gate control time can select
1/4/8ms, so the local oscillator frequency can be got easily according to the counter value and gate time, then
display on LCD according to application requirements.
I/O Port
SC9308 has 5 groups of I/O ports: PA, PB, PC, PE, PF. PA has 8 pins, where 4 pins are used for external
interrupt input. PB has 5 pins, where 3 pins are used for key input interrupt. PC has 4 pins which are shared with
ADC input channel. PE/PF are shared with SEG segments, and can also be used as common IO, 14 pins in total.
So there are max. 31 pins can be used as IO pins.
