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