This manual describes the S3C44B0X microcontroller, a 16/32‑bit ARM7TDMI RISC device featuring an 8 KB cache, integrated SRAM, LCD controller, multiple UARTs, DMA channels, PWM timers, ADCs, and a PLL that can reach up to 75 MHz. It highlights the chip’s low‑power modes, on‑chip peripherals, and flexible memory architecture.
The document includes detailed pin‑out diagrams, descriptions of the clock and reset circuitry, interrupt controller, DMA, UART, I²C, IIS, SIO, ADC, timer/PWM, LCD controller, power supply requirements, and package options (160‑LQFP/160‑FBGA). It also provides electrical characteristics and configuration registers for system designers. This manual is written in Chinese.
