About this manual
The S3C44B0X is an 8‑channel, 10‑bit analog‑to‑digital converter designed by Hangzhou Liti Electronics. It uses a successive‑approximation architecture with programmable sleep mode and offers a maximum conversion rate of 100 KSPS.
The document details the ADC’s functional blocks, conversion time calculations, resolution formulas, and the registers that control conversion operation, including ADCCON, ADCPSR and ADCDAT. It also notes the lack of a sample‑and‑hold circuit and provides typical application guidance for resistive touch‑screen signals. This manual is written in Chinese.
