BOARD USE REQUIREMENTS:

Cables

:

USB A-B cable to connect to virtual serial port on the board. 
You will need LPT cable if you want to program the MCU with 
AVR-JTAG.   You   might   need   other   cables   in   case   of   other 
programmers/debuggers. 

Hardware:

 

Programmer/debugger AVR-JTAG or any compatible tool.

Software:

The   board   is   delivered   with   uC   Linux   pre-loaded.   You   could 
develop projects  for the  board with  Eclipse, IAR,  etc. Please, 
refer to the 

LPC-E2468 Quickstart Guide

 which is on the CD 

for more details on the software requirements. 

PROCESSOR FEATURES:

The 

LPC2468

 processor has the following features:

ARM7TDMI-S processor, running at up to 72 MHz.

512 kB on-chip flash program memory with In-System Programming 
(ISP)   and   In-Application   Programming   (IAP)   capabilities.   Flash 
program memory is on the ARM local bus for high performance CPU 
access.

98 kB on-chip SRAM includes:

64 kB of SRAM on the ARM local bus for high performance CPU 
access.

16   kB   SRAM   for   Ethernet   interface.   Can   also   be   used   as 
general purpose SRAM.

16 kB SRAM for general purpose DMA use also accessible by 
the USB.

2   kB   SRAM   data   storage   powered   from   the   Real-Time   Clock 
(RTC) power domain.

Dual   Advanced   High-performance   Bus   (AHB)   system   allows 
simultaneous   Ethernet   DMA,   USB   DMA,   and   program   execution 
from on-chip flash with no contention.

EMC provides support for asynchronous static memory devices such 
as   RAM,   ROM   and   flash,   as   well   as   dynamic   memories   such   as 
Single Data Rate SDRAM.

Advanced Vectored Interrupt Controller (VIC), supporting up to 32 
vectored interrupts.

General   Purpose   AHB   DMA   controller   (GPDMA)   that   can   be   used 
with the SSP,

I

2

S-bus, and SD/MMC interface as well as for memory-to-memory 

transfers.

Serial Interfaces:

Ethernet   MAC   with   MII/RMII   interface   and   associated   DMA 
controller. These functions reside on an independent AHB bus.

USB 2.0 full-speed dual port Device/Host/OTG Controller with 
on-chip PHY and associated DMA controller.
