ELECTROSTATIC WARNING:
The LPC-2378STK 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 ARM-USB-TINY,
Page 2
you will need USB A-B cable. If you use a software 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:
You can use GCC or other commercial ARM compiler.
PROCESSOR FEATURES:
LPC-2378STK board use microcontroller LPC2378 from NXP with these features:
–
ARM7TDMI-S processor, running at up to 72 MHz.
–
Up to 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.
–
32 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.
–
8 kB SRAM for general purpose DMA use also accessible by the USB.
–
Dual Advanced High-performance Bus (AHB) system that provides for
simultaneous Ethernet DMA, USB DMA, and program execution from on-chip flash
with no contention between those functions. A bus bridge allows the Ethernet DMA
to access the other AHB subsystem.
–
EMC provides support for static devices such as flash and SRAM as well as
off-chip memory mapped peripherals.
–
Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored
interrupts.
–
General Purpose AHB DMA controller (GPDMA) that can be used with the
SSP serial interfaces, the I2S port, and the Secure Digital/MultiMediaCard
(SD/MMC) card port, as well as for memory-to-memory transfers.
–
Serial Interfaces:
•
Ethernet MAC with associated DMA controller. These functions reside
on an independent AHB bus.
•
USB 2.0 full-speed device 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.
Page 3
•
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 and pins. These 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.
•
104 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.
•
One PWM/timer block with support for three-phase motor control.
The PWM has two external count inputs.
•
Real-Time Clock (RTC) with separate power pin, 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.
–
Standard ARM test/debug interface for compatibility with existing tools.
–
Emulation trace module supports real-time trace.
–
Single 3.3 V power supply (3.0 V to 3.6 V).
–
Four reduced power modes: idle, sleep, power down, and deep power down.
–
Four external interrupt inputs configurable as edge/level sensitive. All pins
on PORT0 and PORT2 can be used as edge sensitive interrupt sources.
Page 4
–
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).
–
Two independent power domains allow fine tuning of power consumption
based on needed features.
–
Each peripheral has its own clock divider for further power saving.
–
Brownout detect with separate thresholds for interrupt and forced reset.
–
On-chip power-on reset.
–
On-chip crystal oscillator with an operating range of 1 MHz to 24 MHz.
–
4 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be
used as the system clock. When used as the CPU clock, does not allow CAN and USB
to run.
–
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 on-chip
peripheral functions.

POWER SUPPLY CIRCUIT:
LPC-2378STK is powered by 9VDC/6VAC applied at the power jack. LPC-2378STK
could also be powered by USB (+5V_USB), JTAG (+5V_JLINK) and a battery
(CR2032, Li, 3V) but this battery only powers the 2KB internal SRAM and the RTC
(Real Time Clock).
The consumption of LPC-2378STK is about 190 mA.
RESET CIRCUIT:
LPC-2378STK reset circuit is made with R8 (33k) pull-up, capacitor C20(100nF), D3
(1N4148) and the RST button.
CLOCK CIRCUIT:
Quartz crystal Q1 12 MHz is connected to LPC2378 pin 31 (X1) and pin 33 (X2).
Quartz crystal Q2 32.768 kHz is connected to LPC2378 pin 23 (RTCX1) and pin 25
(RTCX2) and supplies the internal Real Time Clock.
