DMA-ARM7 44B0X Embedded Evaluation Platform
Overview DMA-ARM7 44B0X is a platform that is suitable for code development of Samsung`s S3C44B0X 16/32-bit RISC microcontroller (General ARM) for hand-held device and general applications. DMA-ARM7 44B0X consists of 16-/32-bit RISC (ARM7TDMI) CPU core, 8KB cache, optional internal SRAM, LCD controller (up to 256 color DSTN), 2-ch UART with hand-shake (IRDA1.0, 16-byte FIFO), 4-ch DMA, System manager (chip select logic, FP/ EDO/SDRAM controller), 6-ch timers with PWM, 71-bit general purpose I/O ports, RTC, 8-ch 10-bit ADC, IIC-BUS interface, IIS-BUS interface, Sync. SIO interface and PLL for clock. DMA-ARM7 44B0X consist of boot Flash, SDRAM, LCD&TSP touch screen interface, two serial communication ports, Ethernet interface, USB interface, keyboard interface, IIS(sound) interface, exterior IDE port, Nand Flash, RTC, JTAG interface and 8-SEG. DMA-ARM7 44B0X provide a high performance and low cost solution for embedded engineers.
