Samsung S3C7044/C7048/P7048 Handbook
This handbook describes the Samsung S3C7044, S3C7048 and S3C7048P single‑chip CMOS microcontrollers. It outlines the core SAM47 CPU, memory organization, I/O capabilities, power‑down modes, and peripheral functions such as timers, serial I/O, and interrupt handling. The document includes block diagrams, pin‑assignment tables, and programming guidelines.
Key sections cover the CPU registers, program and data memory structures, clock circuitry, power‑down operation, and detailed specifications like operating voltage, temperature range, and package options. The material is intended for engineers designing with these microcontrollers and for programmers needing register‑level details.
