The SN8P1900 series is a RISC-like 8-bit micro-controller utilized CMOS technology and featured with low power consumption and high performance by its unique electronic structure. The device are designed with 16-bit ADC converter, Programmable Gain Instrucmentation Amplifier, Charge pump, Regulator, LCD driver and 8-level stack buffers. There are four oscillator configurations to select for generating system clock, including High/Low Speed crystal, ceramic resonator or cost-saving RC. This device is a dual clock system using a hi-speed crystal for normal mode operation.
