NK9315A Evaluation Board
A Complete Evaluation Kit for Cirrus Logic EP9315 ARM920T Microcontroller
RS232, CAN, USB Host, 10/100M Ethernet, LCD Interface, VGA, IIS, CF, IDE...
Capable of supporting Linux, WinCE or any embedded operating system
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 MaverickCrunchTM 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 NK9315A 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 NK9315A 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.
