S3C44B0 概述

SAMSUNG's S3C44B0 16/32-bit RISC microprocessor is designed to provide a cost-effective and high performance micro-controller solution for hand-held devices and general applications. To reduce total system cost, S3C44B0 / S3C44B0X also provides the following: 8KB cache, optional internal SRAM, LCD controller, 2-channel UART with handshake, 4-channel DMA, System manager (chip select logic, FP/ EDO/SDRAM controller), 5-channel timers with PWM, I/O ports, RTC, 8-channel 10-bit ADC, IIC-BUS interface, IIS-BUS interface, Sync. SIO interface and PLL for clock.

The S3C44B0 was developed using a ARM7TDMI core, 0.25 um CMOS standard cells, and a memory compiler. Its low-power, simple, elegant and fully static design is particularly suitable for cost-sensitive and power sensitive applications. Also S3C44B0 / S3C44B0X adopts a new bus architecture, SAMBA II (SAMSUNG ARM CPU embedded Microcontroller Bus Architecture).

An outstanding feature of the S3C44B0 is its CPU core, a 16/32-bit ARM7TDMI RISC processor (66MHz) designed by Advanced RISC Machines, Ltd. The architectural enhancements of ARM7TDMI include the Thumb decompressor, an on-chip ICE breaker debug support, and a 32-bit hardware multiplier. By providing a complete set of common system peripherals, the S3C44B0 / S3C44B0X minimizes overall system costs and eliminates the need to configure additional components.
