32-BIT RISC MICROPROCESSOR

Samsung 

DATA SHEET

FEATURES (Continued)

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

Timer

• 3-ch 16-bit Timer with DMA-based or interrupt-

based operation

Watchdog Timer

• 16-bit Watchdog Timer

RCSR (Remote Control Signal Receiver)

• 8-step FIFO

• FIFO interrupt is generated on full (8) step

overflow

RTC (Real Time Clock)

• Full clock feature: sec, min, hour, date, day,

week, month, and year

• 32.768 kHz input clock

• Alarm interrupt

• Time tick interrupt

GPIO (General-Purpose Input/Output) Ports

• 8 external interrupt ports

• 44 multiplexed input/output ports.

S3C2800 MICROCONTROLLER

UART

• 2-channel UART with DMA-based or interrupt

based operation

• Supports 5-bit, 6-bit, 7-bit, or 8-bit serial data

transmit/receive

• Supports hardware handshaking during

transmit/receive operation

• Programmable baud rates (up to 230.4Kbps).

• Supports IrDA 1.0 (up to 115.2Kbps)

• Loop back mode for testing

• Program accessible 16-byte FIFO (2x16 byte

FIFO for transmit/receive data)

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

IIC-BUS Interface

• 2-ch Multi-Master IIC-Bus with interrupt-based

operation

• Serial, 8-bit oriented, bi-directional data

transfers at up to 100 Kbit/s in the standard

mode or up to 400 Kbit/s in the fast mode

Operating Voltage Range

• Core: 1.8 V -0.1 V/+0.15 V

• I/O: 3.3 V ± 0.3 V

Operating Frequency

• Up to 200 MHz.

Package

• 208-pin LQFP
