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
QFP44-10 x10-0.8
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.
APPLICATIONS
* Widely applied in portable audio
control system with LCD.

Interrupt control
SC65X supports two kinds of interrupts: Non-maskable interrupt NMI; maskable interrupt IRQ. Where PRI of non-
maskable interrupt NMI is higher than maskable interrupt IRQ. However, this circuit does not implement NMI
interrupt.
1. Maskable interrupts
SC9308 has 11 maskable interrupts in total without PRI; Setting IRQIP register to determine if the interrupt is
enable. All the maskable interrupts use the same entry address FFF8H.
2. Non-maskable interrupts(reserved)
Non-maskable interrupt NMI, active high. Entry address is FFFCH/FFFDH. This circuit does not implement
NMI function. There is no need to set NMIIP and NMIDP registers.
3. External interrupts
SC9308 has 4 IO input interrupts ExtInt0～3, input by PA0～3 pins; one is used for scan interrupt KSINT,
shares one interrupt source with ExtInt2, corresponding to IRQDP.6. ExtInt3 and IF interrupt IRQIFC share one
interrupt source, corresponding to IRQDP.7. In addition, RTC and Timer2 share one interrupt source.
Watchdog Timer
Watchdog timer adopts independent counter. Watchdog (WDT) is mainly used for program monitor, after counting
overflows, generates reset signal to avoid endless loop or other error execution state. When 75K crystal oscillator
is operating, the longest overflow time is 873.6ms.

SC9308
Operating mode control
SC9308 work in three modes: normal mode, sleep mode, and data maintained mode. Normal mode can be
divided into high-speed mode and low-speed mode. Their difference is the system clock from different sources.
The high speed mode system clock comes from internal RC oscillator or high speed oscillator extended by PC4/5,
while the low speed mode system clock comes from external low speed oscillator.
After power on, CPU clock is provided by internal RC oscillator. When this oscillator is working, the internal
reference module is needed to open. Select clock frequency or switch to the external low speed clock (75KHz) by
setting system control register and clock control register.
The MCU enters sleep mode by setting SLEEP flag of MCU sleep control register MCU_SLP as 1. After the MCU
enters sleep mode, external 75KHz oscillator still works, and CPU clock will be turned off. But it can still response
to internal timer interrupt or external IO interrupt. The circuit enters sleep mode which can reduce the system
standby power dissipation (75KHz crystal oscillator operating, when RTC enables at 3V operating voltage, typical
power dissipation current <5μA). Reset, internal or external interrupt can wake up CPU and make it enter work in
full speed.
When system clock comes from external low speed oscillator, if this oscillator is closed by program, the circuit will
enter data save mode. In this mode, RAM data is saved. The dissipation current is reduced to less than 1uA.
External IO interrupt or reset can make the oscillator work again.
Note: The clock should be switch to 75KHz before entering the sleep mode. Turn off the power reference circuit
and other relative circuits to reduce the power dissipation.
Clock and Reset
SC9308 supports many selectable operating clocks. The clock source can be external 75KHz crystal oscillator,
and can also be the clock generated by internal RC oscillator. When need high precision and high speed
application, it can extend high frequency external oscillator through PC4/5. The structure is as follows:
The system reset occurs when: internal watchdog counting overflows; external Reset pin input low level. The
circuit jumps to the start address of the program from reset address FFFAH and begins working normally.
SC9308 has built in RC oscillator, and frequency of RC oscillator is about 3.2MHz when supply voltage is 3V. If
you need to fast response to internal and external events without high precision, adopt RC oscillator as CPU
clock to make the system process the events quickly. Due to RC oscillator will vary following the voltage and
temperature, PC4/PC5 must be used to extend high-speed oscillator to satisfy the system requirements under
the conditions that need high-precision timing or asynchronous communication, etc..
RC oscillator begins to work after reset, and CPU clock selects the RC oscillator.

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
¾
¾
8-bit programmable timing, generate interrupt after setting the time interval
Arbitrary frequency output
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
¾
¾
Tx pin diplex with PB4, RX pin diplex with PB5
Baud rate presetting register can adjust baud rate freely
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
(PC0/1/4/5). 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.

controls the dataflow direction (set 1 to be output). PUA register and TRISA register can implement input pull-up
or output open-drain of port A. PB has only 5 pins, port PC of PUB register is controlled by 3 registers, TRISC
realizes direction selection, PORTC stores output data, APCON realizes the switch of analog channel and digital
channel.
Register PORTx is readable/writable. When PORTx is set as output, read the last writing data of this register;
when it is set as input, read the pin state.
Display Driver
LCD module can drive maximum 14 SEG x 4 COM LCD board. It is mainly composed of the following parts:
