SC9307P 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 bined to achieve 16 timing length; Built-in real time clock ensures the system uninterrupted counting when it is in sleep state;.
