ELECTROSTATIC WARNING
The LPC-MT-2138 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:
Depends on the used programming/debugging tool. It could be 1.8
meter USB A-B cable to connect ARM-JTAG-EW, ARM-USB-OCD, ARM-USB-TINY
and ARM-USB-TINY-H to USB host on PC or LPT cable in case of ARM-JTAG or
other programming/debugging tools. You will need a serial cable if not for
programming, than for configuring the board.
Hardware:
Programmer/Debugger – some of Olimex programmers are
applicable, for example ARM-JTAG, ARM-JTAG-EW, ARM-USB-OCD, ARMUSB-TINY, ARM-USB-TINY-H or other compatible programming/debugging
tool.
PROCESSOR FEATURES
LPC-MT-2138 board use LPC2138 microcontroller based on a 16/32-bit
ARM7TDMI-S CPU with real-time emulation and embedded trace support, that
combine the microcontroller with 512 kB of embedded high-speed flash memory. A
128-bit wide memory interface and a unique accelerator architecture enable 32-bit
code execution at maximum clock rate. with these features:
–
32 kB of on-chip static RAM and 256/512 kB of on-chip flash program memory.
128-bit wide interface/accelerator enables high-speed 60 MHz operation.
–
In-System Programming/In-Application Programming (ISP/IAP) via on-chip
bootloader software. Single flash sector or full chip erase in 400 ms and
programming of 256 B in 1 ms.
–
EmbeddedICE RT and Embedded Trace interfaces offer real-time debugging
with the on-chip RealMonitor software and high-speed tracing of instruction
execution.
–
Two 8-channel 10-bit ADCs provide a total of up to 16 analog inputs, with
conversion times as low as 2.44 ms per channel.
–
Single 10-bit DAC provides variable analog output.
–
Two 32-bit timers/external event counters (with four capture and four compare
channels each), PWM unit (six outputs) and watchdog.
–
Low power Real-time clock with independent power and dedicated 32 kHz
clock input.
–
Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400
kbit/s), SPI and SSP with buffering and variable data length capabilities.
–
Vectored interrupt controller with configurable priorities and vector addresses.
–
Up to forty-seven 5 V tolerant general purpose I/O pins
–
Up to nine edge or level sensitive external interrupt pins available.
–
60 MHz maximum CPU clock available from programmable on-chip PLL with
settling time of 100 ms.

–
On-chip integrated oscillator operates with external crystal in range of 1 MHz to
30 MHz and with external oscillator up to 50 MHz.
–
Power saving modes include Idle and Power-down.
–
Individual enable/disable of peripheral functions as well as peripheral clock
scaling down for additional power optimization.
–
Processor wake-up from Power-down mode via external interrupt or BOD.
–

POWER CIRCUIT
LPC-MT-2138 can is typically power supplied with +9VAC or 12VDC from power
jack.
RESET CIRCUIT
LPC-MT-2138 reset circuit includes R6 (10k) pull-up, U3 (MCP130T), LPC2138 pin
57 (RST) and RST button.
CLOCK CIRCUIT
Quartz crystal Q1 14.7456 MHz is connected to LPC2138 pin 61 (X2) and pin 62 (X1).
Quartz crystal Q2 32.768 KHz is connected to LPC2138 pin 3 (RTCX1) and pin 5
(RTCX2).

JUMPER DESCRIPTION
VREF
Connects LPC2138 pin 63 (VREF) to 3.3V.
Default state is closed.
DAC/PWM
When this jumper is in position DAC - connects LIGHT_LCD signal to LPC2138 pin 9
(AOUT); when this jumper is in position PWM – connects LIGHT_LCD signal to LPC2138 pin
1 (PWM5).
Default state is PWM – closed.
JRST
Enables LPC2138 reset via UART.
Default state is open.
BSL
This jumper is connected to LPC2138 pin 41 (P0.14). When this jumper is open, P0.14
is pulled-up to 3.3V via R1 (22k) , when is closed P0.14 is pulled-down via R24 (1k).
LOW level on pin P0.14 immediately after reset is considered as an external hardware
request to start the ISP command handler. If there is no request for the ISP command
handler execution (P0.14 is sampled HIGH after reset), a search is made for a valid
user program. If a valid user program is found then the execution control is
transferred to it. If a valid user program is not found, the auto-baud routine is
invoked.
Default state is open.
DBG
Enables JTAG debug operations.
Default state is closed.
INPUT/OUTPUT
Reset button with name RST, connected to LPC2138 pin 57 (RST).
User button with name B1, connected to LPC2138 pin 45 (P0.15).
User button with name B2, connected to LPC2138 pin 46 (P0.16).
User button with name B3, connected to LPC2138 pin 55 (P0.20).
User button with name B4, connected to LPC2138 pin 15 (P0.30).
User button with name B5, connected to LPC2138 pin 34 (P0.9).
LCD 16x2 display with BACKLIGHT, connected as follows: RS – to LPC2138 pin 12
(P1.17); R/W – to LPC2138 pin 4 (P1.19); E – to LPC2138 pin 8 (P1.18), DB4 – to
LPC2138 pin 48 (P1.20), DB5 – to LPC2138 pin 44 (P1.21), DB6 – to LPC2138 pin 40
(P1.22), DB7 to LPC2138 pin 36 (P1.23).
