Holtek Semiconductor was established in 1983 and is a global leader in microcontrollers and peripheral semiconductor devices. Holtek microcontrollers include a wide range of fully integrated digital and analog functions such as A/D converters, LCD drivers, PWM generators, high current LED drivers, SPI interfaces, USB drivers etc.
The guide introduces Holtek Semiconductor and its history, then focuses on the /c162s microcontroller family. It highlights the 8‑bit RISC core and the wide range of integrated digital and analog peripherals such as A/D converters, LCD drivers, PWM generators, high‑current LED drivers, SPI and USB interfaces.
Detailed tables list the electrical specifications, memory sizes, clock options and package types for each device variant, including mask, OTP and Flash versions. The document also outlines Holtek’s development strategy, marketing network and the broad application areas for the /c162s series.
