SC9321

SC9321 AUDIO SYSTEM CONTROL MCU WITH DTS PLL DESCRIPTION SC9321 is an audio system controller which realizes the AM/FM tune receiver (DTS) and other functions. It is based on Silan’s 8-bit MCU SC65PX and can be operating under low voltage. Built-in LCD driver which can drive max. 4X23 segments display; 44 configurable I/O ports; three 8-bit counters, where two of them can be together to implement 16-bit timing length, and another timer is equipped with input capture functions; Built-in real time clock ensures the system continuously counting when it is in sleep state; 9 interrupt sources including four external interrupts, which makes the system response to various internal or external events quickly. The serial communication circuit with selectable multiple operating modes enhanced the expansibility of the system. Built-in 3.2MHz RC oscillator with external 75KHz oscillator can make a balance between power dissipation and speed. In high speed application, it can extend external h...
