lpc2468

This project is first open source platform (hardware and software) with LPC2468 microcontroller with 512kB flash, external memory bus, USB 2.0 OTG/Host, 10/100 ethernet, SD/MMC, I2S, real-time emulation, accelerator architecture. The feature rich development board consist of several interfaces: ... [More] Interfaces: 2x CAN with High Speed CAN Transceiver + headers, 2x UART (only Rx/Tx) with ±15kV ESD-Protected, up to 250kbps, True RS-232 Transceiver. One DB9, one header 1x IRdA with Serial Infrared Transceiver SIR, 115.2 kbit/s, 1x SB OTG using ISP1301 Universal Serial Bus On-The-Go transceiver, 1x USB host using USB Power Switch and Over-Current Protection, 1x USB device with soft connect and good link LED and Separate headers for I2C, SPI, I2S, 6PWM. User interface consist of Graphical LCD 128x64 as memory mapped device with own CS, four-way "joystick" with central button and 3 separate pushbuttons, read as memory mapped device through own CS, 2x PS/2 connector (via FPGA), 1x VGA conector (via FPGA). The on-board FPGA is 144 pin Spartan 3E pinout (suitable for 100k and 250k devices) with On-board Platform Flash In-System Programmable with separate JTAG conector. FPGA has Separate JTAG connector and Dedicated 25MHz oscillator for FPGA system clock. There is also 50MHz available from ethernet reference clock output. All IO pins are equiped with headers, Power supply headers (3.3V, 2.5V and 1.2V) are provided and LPC FPGA is connected via memory interface: OE, WE, EINT0...EINT3, separate CS, 11 Address lines and 8-bit data bus. There is additional LPC connection via SPI and I2C. Sound interface uses Low-voltage low-power stereo audio CODEC with DSP features connected to I2S of the microcontroller, BNC connectors for L/R inputs and outputs, One 8 W stereo BTL audio output amplifier with DC volume control, which may be manual or with LPC2400 DAC output. On board PHY enables use of the interlnal ethernet controller with 10/100 Base-TX RJ45 connector with LEDs and integrated magnetics. The PoE DC/DC is integrated on-board for testing PoE applications. Memory is quite large providing many applications and (RT)OSes to this board. There is onr Intel strata flash P33 and P30, with separate 1.8V available for P30. DRAM is 1 Meg x 32 x 4 banks 32 bit SDRAM. Additionally, there is MMC/SD(IO) socket and one Serial dataflash up to 32Mbit. The analog IO may be used for high precision analog signal aquisition. There are two Dual, Zero-Drift, Digitally Programmable Sensor Signal Amplifiers, one 16-Bit, 4-Channel Serial output ADC, a Quad Channel, Low Power, 16-Bit, Serial Input DAC and complete Headers for LPC AD0 and DACOUT.
