INTRODUCTION:
LPC-2478STK is a starter kit which uses MCU LPC2478 from NXP. This
powerful MCU supports various serial interfaces such as USB host, USB
device, UART, CAN, etc. Additionally, you will find also audio input and
output as well as MP3 decoder, digital accelerometer, JTAG, Ethernet,
touchscreen TFT display 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 powerful applications to be used in a wide range of situations.

ELECTROSTATIC WARNING:
The LPC-2478STK board is shipped in protective anti-static packaging. The
board must not be subject to high electrostatic potentials. General practice
for working with static sensitive devices should be applied when working with
this board.
BOARD USE REQUIREMENTS:
Cables:
You will need different cables depending on the used
programming/debugging tool. If you use Olimex's ARM-JTAG,
you will need a LPT cable. If you use ARM-USB-OCD or ARMUSB-TINY, you will need USB A-B cable. If you use a software
Page 2
programmer such as FlashMagic, you may need RS232 or other
cables.
Hardware:
Programmer/Debugger – ARM-JTAG, ARM-USB-TINY or ARMUSB-OCD or other compatible programming/debugging tool.
Software:
The board comes pre-loaded with Uboot and the CD contains
ucLinux image you can copy to USB flash disk and boot. You
can use GCC or other commercial ARM compiler if you want to
develop without ucLinux RTOS.
PROCESSOR FEATURES:
LPC-2478STK board use MCU LPC2478 from NXP with these 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 RTC power domain.
LCD controller, supporting both Super-Twisted Nematic (STN) and
Thin-Film Transistors (TFT) displays.
-
Dedicated DMA controller.
-
Selectable display resolution (up to 1024 × 768 pixels).
-
Supports up to 24-bit true-color mode.

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
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.
Page 3

-
USB 2.0 full-speed dual-port device/host/OTG controller with
on-chip PHY and associated DMA controller.
-
Four UARTs with fractional baud rate generation, one with
modem control I/O, one with IrDA support, all with FIFO.
-
CAN controller with two channels.
-
SPI controller.
-
Two SSP controllers, with FIFO and multi-protocol capabilities.
One is an alternate for the SPI port, sharing its interrupt. SSPs
can be used with the GPDMA controller.
-
Three I2C-bus interfaces (one with open-drain and two with
standard port pins).
-
I2S (Inter-IC Sound) interface for digital audio input or output. It
can be used with the GPDMA.
Other peripherals:
-
SD/MMC memory card interface.
-
160 General purpose I/O pins with configurable pull-up/down
resistors.
-
10-bit ADC with input multiplexing among 8 pins.
-
10-bit DAC.
-
Four general purpose timers/counters with 8 capture inputs and
10 compare outputs. Each timer block has an external count
input.
-
Two PWM/timer blocks with support for three-phase motor
control. Each PWM has an external count inputs.
-
Real-Time Clock (RTC) with separate power domain. Clock
source can be the RTC oscillator or the APB clock.
-
2 kB SRAM powered from the RTC power pin, allowing data to be
stored when the rest of the chip is powered 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 power supply (3.0 V to 3.6 V).

4 MHz internal RC oscillator trimmed to 1 % accuracy that can
optionally be used as the system clock.

Three reduced power modes: idle, sleep, and power-down.

Four external interrupt inputs configurable as edge/level sensitive. All
pins on port 0 and port 2 can be used as edge sensitive interrupt
sources.

Processor wake-up from Power-down mode via any interrupt able to
operate during Power-down mode (includes external interrupts, RTC
interrupt, USB activity, Ethernet wake-up interrupt, CAN bus activity,
port 0/2 pin interrupt).

Two independent power needed features.

Each peripheral has its own clock divider for further power saving.
These dividers help reduce active power by 20 % to 30 %.

Brownout detect with separate thresholds for interrupt and forced
reset.
Page 4

On-chip power-on reset.

On-chip crystal oscillator with an operating range of 1 MHz to 24
MHz.

On-chip PLL allows CPU operation up 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 simplified board testing.

Versatile pin function selections allow more possibilities for using onchip peripheral functions.

Standard ARM test/debug interface for compatibility with existing
tools.

Emulation trace module supports real-time trace.

BOARD LAYOUT:
POWER SUPPLY CIRCUIT:
LPC-2478STK is powered by +(9-12)VDC/6VAC applied at the power jack.
LPC-2478STK could also be powered by a battery (CR2032, Li, 3V) but this
battery only powers the 2KB internal SRAM and the RTC (Real Time Clock).
The consumption of LPC-2478STK varies depending on the supplied power
but at +10VDC it is about 250mA.
RESET CIRCUIT:
LPC-2478STK reset circuit is made with R68(47k) pull-up, capacitor
C20(100nF) and the RST button.
CLOCK CIRCUIT:
Quartz crystal 12 MHz is connected to LPC2478 pin 44 (XTAL1) and pin 46
(XTAL2).
Quartz crystal 32.768 kHz is connected to LPC2478 pin 34 (RTX1) and pin
36 (RTX2) and supplies the internal Real Time Clock.

PHY_PD.
Default state is no jumper (opened).
EXT/JLINK
This jumper controls the JLINK +5V power line (pin19) of the JTAG
and the +5VDC power supply of the board.
If 1-2 are shorted, the JLINK +5V power line (pin19) from the JTAG
interface supplies the board with +5VDC.
If 2-3 are shorted, the board is supplied with +5VDC from the
+5VDC voltage regulator.
