SC9307P
AUDIO SYSTEM CONTROL MCU WITH ANALOG RADIO FUNCTION
DESCRIPTION
SC9307P is a SOC based on Silan’s 8-bit MCU SC65PX for analog
radio DFR control with low power dissipation. Built-in LCD driver which
can drive 34 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 and 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.

SC9307P
Ø 8-bit programmable timing, generate interrupt after setting the time interval
Ø Arbitrary frequency output
Ø External clock frequency division
T0/T1/T2 has one control register and one pre-assignment register.
UART
SC9307P has built-in full duplex async communication interface with three modes: 8bit variable baud rate, 9bit
fixed baud rate or variable baud rate communication.
Ø Pin Tx diplex with PB4, pin RX diplex with PB5
Ø Baud rate presetting register can adjust baud rate freely
Ø Transmitting and receiving interrupt cooperation dual buffer can guarantee the high speed
communication stable and reduce the CPU load.
8-bit ADC
8-bit AD converter is mainly used for keyboard scan and 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, ADC input channel is not effected. One AD conversion
needs 12 clock cycles, and the typical conversion time of ADC is 160µs with 75KHz oscillator.
Frequency counting module
This module mainly includes local oscillator signal amplifier and gate control counting. FM or AM local oscillator
signal is counted by a 16-bit counter after amplified. This counter gate control time can be selected as 1/4/8ms,
so the local oscillator frequency can be got easily according to the counter value and gate time.
I/O Port
www.DataShSeCet943U0.c7oPmhas 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 5 pins, where 4 pins are
shared with ADC input channel. PC.6 is used for ADC external reference voltage input. PE/PF are general I/O,
16 pins in total. So there are max. 34 pins can be used as IO pins.
There are three registers for ports PA/B. Data register PORTx latches the output data, direction register TRISx
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.
Usage of port PE/F is different from PA/B/C. Just take port PE as an example, lower 4-bit of register PECFGL is
used for controlling PE.3~0 ports. When PECFGL.3 is set as 1, PE.3 acts as output and when PECFGL.3 is set
as 0, PE.3 acts as input. Lower 4-bit of register PECFGH is used for controlling PE.7~4 ports. When PECFGH.3
is set as 1, PE.7 acts as output and when PECFGH.3 is set as 0, PE.7 acts as input.
Usage and function of PF are same as PE, used as output after reset. Control mode of PFCFGL, PFCFGH are
same as PECFGL, PECFGH.
