ELECTROSTATIC WARNING
The LPC-P2138 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-P2138 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.
–

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.
–
Single power supply chip with POR and BOD circuits:
–
