mbest NK9315 Evaluation Board

The Cirrus Logic EP9315 is a highly integrated system-on-chip processor that paves the way for next-generation consumer and industrial electronic products. The EP9315 features an advanced 200 MHz ARM920T processor designed with a memory management unit (MMU) and is augmented by the MaverickCrunch™ coprocessor to accelerate the ARM920T's single- and double-precision integer and floating-point processing capabilities. It has separate 16KB data cache and 16KB instruction cache and includes 1/10/100 ethernet, IDE storage peripherals, keypad, a three-port USB 2.0 full-speed host (OHCI), running at 12 Mbps, and three UARTs. Additionally the EP9135 includes a 2D graphics accelerator, integrated LCD controller, touchscreen and high quality audio to enable easy to use products with vibrant multimedia capabilities. A highly flexible memory interface provides compatibility with SDRAM, SRAM, Flash, and ROM.

Embest NK9315 Evaluation Board takes full features of the high-performance Cirrus Logic EP9315 microcontroller system-on-chip and full Bus and peripheral signals are expanded through interfaces on board including IDE, CAN, LCD & Touchscreen, VGA/S-Video/Composive output, Ethernet, PS/2, UART, USB Host, IIS, CF card, keyboard, Jtag, etc. There is also a PCMCIA interface on the rear of the board which supports one 16-bit PCMCIA PC Card to add memory, mass storage and I/O capabilities to computer systems and thus can be used to further broaden the options of a designer's platform. The LCD and Raster interface of EP9315 is with a graphics accelerator which is used in the system to off load graphics operations from the processor.

The board supports high-lever operating systems such as Linux, Windows CE and other embedded operating systems. The board's code support package includes WINCE.net 4.2 BSP, embedded Linux source code and a download utility.

Typical applications of Embest NK9315 board are POS (Point-of sale), internet audio, internet access devices, industrial computers, test and measurement equipments, digital media servers, industrial controls, biometric security systems, etc.
