INTRODUCTION

This user’s manual describes SAMSUNG's S3C2443X 16/32-bit RISC microprocessor. SAMSUNG’s S3C2443X
is designed to provide hand-held devices and general applications with low-power, and high-performance micro­controller solution in small die size. To reduce total system cost, the S3C2443X includes the following
components.

The S3C2443X is developed with ARM920T core, 0.13um CMOS standard cells and a memory complier. Its low­power, simple, elegant and fully static design is particularly suitable for cost- and power-sensitive applications. It
adopts a new bus architecture known as Advanced Micro controller Bus Architecture (AMBA).

The S3C2443X offers outstanding features with its CPU core, a 16/32-bit ARM920T RISC processor designed by
Advanced RISC Machines, Ltd. The ARM920T implements MMU, AMBA BUS, and Harvard cache architecture
with separate 16KB instruction and 16KB data caches, each with an 8-word line length.

By providing a complete set of common system peripherals, the S3C2443X minimizes overall system costs and
eliminates the need to configure additional components. The integrated on-chip functions that are described in
this document include:

ROM/SRAM bus (ROM Bank0~Bank5) and one
for the DRAM bus (SDRAM Bank0~Bank1)

• Address space: 64M bytes for Rom bank0 ~
bank5, 128M bytes for SDRAM bank0 ~ bank1.

• Supports programmable 8/16-bit data bus width
for ROM/SRAM bank and programmable 16/32­bit data bus width for DRAM bank

• Fixed bank start address from Rom bank 0 to
bank 5 and SDRAM bank 0 to bank1.

• Eight memory banks:

– Six memory banks for ROM, SRAM, and

others (NAND/CF etc.).

– Two memory banks for Synchronous DRAM.

• Complete Programmable access cycles for all
memory banks.

NAND Flash Boot Loader

• Supports booting from NAND flash memory.
(Only 8bit boot support)

• 4KB internal buffer for booting.

• Supports storage memory for NAND flash

memory after booting.

• Supports Advanced NAND flash

Cache Memory

• 64-way set-associative cache with I-Cache
(16KB) and D-Cache (16KB).

• 8words length per line with one valid bit and two
dirty bits per line.

• Pseudo random or round robin replacement
algorithm.

• Write-through or write-back cache operation to
update the main memory.

• The write buffer can hold 16 words of data and
four addresses.

Clock & Power Manager

• On-chip MPLL and EPLL:
EPLL generates the clock to operate USB Host,
IIS, UART, etc.
MPLL generates the clock to operate MCU at
maximum 533Mhz @ 1.375V.

• Clock can be fed selectively to each function
block by software.

• Power mode: Normal, Idle, STOP and Sleep
mode
Normal mode: Normal operating mode
Idle mode: The clock for only CPU is stopped.
STOP mode: All clocks are stopped.
Sleep mode: The Core power including all
peripherals is shut down.

• Supports external wait signals to expand the bus
cycle.

• Supports self-refresh mode in SDRAM for
