PHILIPS SEMICONDUCTORS INC.LPC2129
16/32 BIT ARM7TDMI-S: 16/32 bit LPC2129 with 256K Bytes program
Flash, 16K bytes RAM, RTC, 2X32bit timers, 7xCCR, 2XCAN, ADC,
2xSPI, 12C, 6xPWM,WDT,5V tolerant I/O, up to 60Mhz operation.
|
|
12 MHz Crystal allows easy communication setup.
|
|
Two on board voltage regulators 1.8V and 3.3V
. Input to this will be from external +5V DC Power supply
through a 9-pin DSUB connector. One power LED to indicate
the presence of 5V. |
|
Two RS232 interface circuits with 9 pin DSUB
connectors: UARTO is used by the Boot loader program, to program
LPC2129 Flash memory without external programmer. UART1 is
general purpose RS232 and may be used by user program. |
|
LCD 16 x 2 display: LCD display is 16 X 2
characters, working in 4-bit mode. |
|
Eight general purpose LED's connected to output
ports of the controller. |
|
Four push buttons connected to inputs of the
controller. |
|
Reset switch : It is possible to apply RESET
externally by the RESET switch on the board |
|
The useful port lines (extension ports) of
controller are brought out for the user. |
|
Standard JTAG connector with ARM 2 X 10 pin
layout for programming / debugging with ARM-JTAG. |
|
I2C bus interface to DS1302 (RTC) and 24c16
(NVROM) |
|
SPI bus interface to MCP 3202 (12-bit ADC). |
|
CAN bus transceivers – two numbers of PCA
82C250. |
|
Standard 26-pin FRC connector compatible with
some ALS standard interfaces. |
