By integrating various common system peripherals, the S3C2800 minimizes the overall system cost and eliminates the need to configure additional components. The integrated on-chip functions are summarized as follows : 

• PCI BUS interface (32-bit, up to 66MHz). 
• 1.8V static ARM920T CPU core with 16KB I/D (Instruction/Data) cache. (Harvard bus architecture up to 200MHz). 
• External memory controller. (FP/EDO/SDRAM control, Chip select logic). 
• 4-ch general DMAs with external request pins. 
• 2-ch UART with handshake (IRDA1.0, 16-byte FIFO), Modem Interface. 
• 2-ch multi-master IIC-BUS controller. 
• 3-ch 16-bit timer. 
• 16-bit Watchdog timer. 
• 44 general-purpose GPIO ports including 8 external interrupt source. 
• Power management: Normal, Slow, and Idle modes. 
• RTC with calendar function. 
• On-chip PLL clock generator.

FEATURES

Interrupt Controller

• 34 Interrupt sources. (3 for Timers, 6 for UART, 8 for External interrupts, 4 for DMA, 2 for RTC, 2 for IIC, 2 for RCSR (Remote Control Signal Receiver), and 7 for PCI)) 
• Software polling Interrupt mode 
• Selectable level- or edge-triggered external interrupts source 
• Programmable IRQ/FIQ for each interrupt request 
• Supports FIQ (Fast Interrupt Request) for very urgent interrupt request

DMA Controller 

• 4-channel general-purpose Direct Memory Access controller without CPU intervention. 
• Support memory to memory, memory to I/O and I/O to I/O DMA operations of the following 6 types: Software, 3 internal function blocks (UART0, UART1, Timer), and 2 External requests 
• Burst transfer mode to enhance the transfer rate on the FPDRAM, EDODRAM and SDRAM
