S3C2440AL-40 Product Details

This manual describes SAMSUNG's S3C2440AL-40 16/32-bit RISC microprocessor. SAMSUNG’s S3C24440X 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 S3C2440AL-40 includes the following components separate 16KB Instruction and 16KB Data Cache, MMU to handle virtual memory management, LCD Controller (STN & TFT), NAND Flash Boot Loader, System Manager (chip select logic and SDRAM Controller), 3-ch UART, 4-ch DMA, 4-ch Timers with PWM, I/O Ports, RTC, 8-ch 10-bit ADC and Touch Screen Interface, Camera interface, IIC-BUS Interface, IIS-BUS Interface, USB Host, USB Device, SD Host & Multi-Media Card Interface, 2- ch SPI and PLL for clock generation. 

The S3C2440AL-40 has been developed using an ARM920T core, 0.13um CMOS standard cells and a memory complier. Its low-power, 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 S3C2440AL-40 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.

– Two memory banks for ROM/SRAM/Synchronous DRAM.

• Complete Programmable access cycles for all memory banks.

• Supports external wait signals to expend the bus cycle.

• Supports self-refresh mode in SDRAM for powerdown.

• Supports various types of ROM for booting (NOR/NAND Flash, EEPROM, and others).

NAND Flash Boot Loader

• Supports booting from NAND flash memory.

• 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).
