INTRODUCTION:
LPC-2478STK is a starter kit which uses MCU LPC2478 from NXP. This
owerful MCU su orts various serial interfaces such as USB host, USB
device, UART, CAN, etc. Additionally, you will find also audio in ut and
out ut as well as MP3 decoder, digital accelerometer, JTAG, Ethernet,
touchscreen TFT dis lay and SD/MMC card connector on this board. All this
along with the ARM7TDMI-S™ architecture and uC Linux allow you to build
a diversity of owerful a lications to be used in a wide range of situations.

ELECTROSTATIC WARNING:
The LPC-2478STK board is shi ed in rotective anti-static ackaging. The
board must not be subject to high electrostatic otentials. General ractice
for working with static sensitive devices should be a lied when working with
this board.
BOARD USE REQUIREMENTS:
Cables: You will need different cables de ending on the used
rogramming/debugging tool. If you use Olimex's ARM-JTAG,
you will need a LPT cable. If you use ARM-USB-OCD or ARM-
USB-TINY, you will need USB A-B cable. If you use a software
Page 2

rogrammer such as FlashMagic, you may need RS232 or other
cables.
Hardware: Programmer/Debugger – ARM-JTAG, ARM-USB-TINY or ARM-
USB-OCD or other com atible rogramming/debugging tool.
Software: The board comes re-loaded with Uboot and the CD contains
ucLinux image you can co y to USB flash disk and boot. You
can use GCC or other commercial ARM com iler if you want to
develo without ucLinux RTOS.
PROCESSOR FEATURES:
PC-2478STK board use MCU PC2478 from NXP with these features:
ARM7TDMI-S rocessor, running at u to 72 MHz.
512 kB on-chi flash rogram memory with In-System Programming
(ISP) and In-A lication Programming (IAP) ca abilities. Flash
rogram memory is on the ARM local bus for high erformance CPU
access.
98 kB on-chi SRAM includes:
- 64 kB of SRAM on the ARM local bus for high erformance CPU
access.
- 16 kB SRAM for Ethernet interface. Can also be used as general
ur ose SRAM.
- 16 kB SRAM for general ur ose DMA use also accessible by the
USB.
- 2 kB SRAM data storage owered from the RTC ower domain.
LCD controller, su orting both Su er-Twisted Nematic (STN) and
Thin-Film Transistors (TFT) dis lays.
- Dedicated DMA controller.
- Selectable dis lay resolution (u to 1024 × 768 ixels).
- Su orts u to 24-bit true-color mode.
Dual Advanced High- erformance Bus (AHB) system allows
simultaneous Ethernet DMA, USB DMA, and rogram execution from
on-chi flash with no contention.
EMC rovides su ort for asynchronous static memory devices such
as RAM, ROM and flash, as well as dynamic memories such as Single
Data Rate SDRAM.
Advanced Vectored Interru t Controller (VIC), su orting u to 32
vectored interru ts.
General Pur ose AHB DMA controller (GPDMA) that can be used with
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 inde endent AHB.
Page 3

- USB 2.0 full-s eed dual- ort device/host/OTG controller with
on-chi PHY and associated DMA controller.
- Four UARTs with fractional baud rate generation, one with
modem control I/O, one with IrDA su ort, all with FIFO.
- CAN controller with two channels.
- SPI controller.
- Two SSP controllers, with FIFO and multi- rotocol ca abilities.
One is an alternate for the SPI ort, sharing its interru t. SSPs
can be used with the GPDMA controller.
- Three I2C-bus interfaces (one with o en-drain and two with
standard ort ins).
- I2S (Inter-IC Sound) interface for digital audio in ut or out ut. It
can be used with the GPDMA.
Other eri herals:
- SD/MMC memory card interface.
- 160 General ur ose I/O ins with configurable ull-u /down
resistors.
- 10-bit ADC with in ut multi lexing among 8 ins.
- 10-bit DAC.
- Four general ur ose timers/counters with 8 ca ture in uts and
10 com are out uts. Each timer block has an external count
in ut.
- Two PWM/timer blocks with su ort for three- hase motor
control. Each PWM has an external count in uts.
- Real-Time Clock (RTC) with se arate ower domain. Clock
source can be the RTC oscillator or the APB clock.
- 2 kB SRAM owered from the RTC ower in, allowing data to be
stored when the rest of the chi is owered off.
- WatchDog Timer (WDT). The WDT can be clocked from the
internal RC oscillator, the RTC oscillator, or the APB clock.
Single 3.3 V ower su ly (3.0 V to 3.6 V).
4 MHz internal RC oscillator trimmed to 1 % accuracy that can
o tionally be used as the system clock.
Three reduced ower modes: idle, slee , and ower-down.
Four external interru t in uts configurable as edge/level sensitive. All
ins on ort 0 and ort 2 can be used as edge sensitive interru t
sources.
Processor wake-u from Power-down mode via any interru t able to
o erate during Power-down mode (includes external interru ts, RTC
interru t, USB activity, Ethernet wake-u interru t, CAN bus activity,
ort 0/2 in interru t).
Two inde endent ower needed features.
Each eri heral has its own clock divider for further ower saving.
These dividers hel reduce active ower by 20 % to 30 %.
Brownout detect with se arate thresholds for interru t and forced
reset.
Page 4

On-chi ower-on reset.
On-chi crystal oscillator with an o erating range of 1 MHz to 24
MHz.
On-chi PLL allows CPU o eration u to the maximum CPU rate
without the need for a high frequency crystal. May be run from the
main oscillator, the internal RC oscillator, or the RTC oscillator.
Boundary scan for sim lified board testing.
Versatile in function selections allow more ossibilities for using on-
chi eri heral functions.
Standard ARM test/debug interface for com atibility with existing
tools.
Emulation trace module su orts real-time trace.

BOARD LAYOUT:
POWER SUPPLY CIRCUIT:
PC-2478STK is owered by +(9-12)VDC/6VAC a lied at the ower jack.
LPC-2478STK could also be owered by a battery (CR2032, Li, 3V) but this
battery only owers the 2KB internal SRAM and the RTC (Real Time Clock).
The consum tion of LPC-2478STK varies de ending on the su lied ower
but at +10VDC it is about 250mA.
RESET CIRCUIT:
PC-2478STK reset circuit is made with R68(47k) ull-u , ca acitor
C20(100nF) and the RST button.
CLOCK CIRCUIT:
Quartz crystal 12 MHz is connected to LPC2478 in 44 (XTAL1) and in 46
(XTAL2).
Quartz crystal 32.768 kHz is connected to LPC2478 in 34 (RTX1) and in
36 (RTX2) and su lies the internal Real Time Clock.

JUMPER DESCRIPTION:
CAN_D
CAN Disable. If this jum er is closed, the CAN is disabled.
Default state is o en.
CAN_T
This jum er assures correct work of the CAN. At each end of the
bus it should be closed. This means that if you have only two
devices with CAN, the jum ers of both devices should be closed. If
you have more than two devices, only the two end-devices should
be closed.
Default state is closed.
-10V_E
This jum er, when closed, su lies -10 V voltage to the on board
LCD anel.
Default state is closed.
15V_E
This jum er, when closed, su lies 15 V voltage to to the on board
LCD anel.
Default state is closed.
3.3V_E
This jum er, when closed, su lies 3.3 V voltage to the VDD1-10
ins of the MCU.
Default state is closed.
3.3VA_E
This jum er, when closed, su lies 3.3 V voltage to the VDDA in
of the MCU.
Default state is closed.
VREF_E
This jum er, when closed, su lies 3.3 V reference voltage to the
VREF in of the MCU.
Default state is closed.
IRDA_ S_E
IRDA_LowS eed_Enable jum er – o ened if there is no IrDA
module or it is disabled.
Default state is o ened if your board doesn't have an IrDA
connector.
I2SRX_SDA
IrDA TX in ut in jum er – o ened if there is no IrDA module
or it is disabled.
Default state is o ened if your board doesn't have an IrDA
connector.
