LPC900 Education and Training Kit

The LPC900 Education and Training Kit (LPC900-ETK) provides extensive add-on hardware to the LPC900 devices. The LPC900-ETK connects to Keil MCB900 or EPM900 via a 28-pin DIP-to-DIP cable. All LPC900 pins can be flexible connected via cables. The LPC900-ETK provides the following peripherals that may be connected to each I/O-pin of the LPC900 device:

• independent 5V power regulator
• RS232 interface including driver (configurable via jumpers)
• 8 switches
• 8 keys
• loudspeaker
• 2 relays outputs
• 2 potentiometers (0 to 3.3V)
• 2-bit gray encoder with key function
• two standard LCD display connectors (1x14 and 2x7 pins)
• integrator 0-5V
• PS/2 connector (mini-DIN)
• 32-pin connector for expansions boards
• D/A output driver

In addition the I²C bus of the LPC900 may be connected to the following devices:

• SAA1064 including 4-digit 7 segment display
• PCF8574 IO-Expander
• DS1621 temperature sensor
