INTRODUCTION
Samsung's S3C4530A 16/32-bit RISC microcontroller is a cost-effective, high-performance microcontroller
solution for Ethernet-based systems. An integrated Ethernet controller, the S3C4530A, is designed for use in
managed communication hubs and routers.
The S3C4530A is built around an outstanding CPU core: the 16/32-bit ARM7TDMI RISC processor designed by
Advanced RISC Machines, Ltd. The ARM7TDMI core is a low-power, general purpose microprocessor macro-cell
that was developed for use in application-specific and custom-specific integrated circuits. Its simple, elegant, and
fully static design is particularly suitable for cost-sensitive and power-sensitive applications.
The S3C4530A offers a configurable 8-Kbyte unified cache/SRAM and Ethernet controller which reduces total
system cost. Most of the on-chip function blocks have been designed using an HDL synthesizer and the
S3C4530A has been fully verified in Samsung's state-of-the-art ASIC test environment.
Important peripheral functions include two HDLC channels with buffer descriptor, two UART channels with full
modem interface signal and 32byte buffer, 2-channel GDMA, two 32-bit timers, and 26 programmable I/O ports.
On-board logic includes an interrupt controller, DRAM/ SDRAM controller, and a controller for ROM/SRAM and
flash memory. The System Manager includes an internal 32-bit system bus arbiter and an external memory
controller.
