Page 3: Board Use Requirements
Software: The board is delivered with uC Linux pre-loaded. You could develop projects for the board with Eclipse, IAR, etc. Please, refer to the LPC-E2468 Quickstart Guide which is on the CD for more details on the software requirements. PROCESSOR FEATURES: The LPC2468 processor has the following features: ●... - Page 4 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.
- Page 5 ● 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.

JUMPER DESCRIPTION: 3.3V_E This jumper, when closed, supplies 3.3 V voltage to the VDD1-10 pins of the MCU. Default state is closed. 3.3VA_E This jumper, when closed, supplies 3.3 V voltage to the VDDA pin of the MCU. Default state is closed. VREF_E This jumper, when closed, supplies 3.3 V reference voltage to the VREF pin... - Page 11 BDS_E Boundary scan enable. Default state is open. BAT/EXT This jumper controls the input power supply for the VBAT pin. If 1-2 are shorted, the external battery is connected to VBAT pin. If 2-3 are shorted, the VBAT pin is supplied by the board +3.3V supply.
