SC51P18A16_Datasheet
LOW POWER 8-BIT MCU INTEGRATED WITH LCD DRIVER AND CHARGE
PUMP
DESCRIPTION
SC51P18A16 is an 8-bit MCU integrated with LCD driver and charge
pump. It uses SC51 core with built-in 16K-byte OTP and 512-byte
RAM, 8MHz high precision RC oscillator, rail-to-rail analog comparator,
flexible clock system, rich timer resource and communication interface,
which designed for various control applications. It features 1.8V~3.6V
operating voltage range, low display current in IDLE mode, and
ultra-low Stop current, which makes it well suitable for the
battery-powered systems.
