The maximum clock frequency for the P89LPC9103FTK,115 is 12 MHz, but it can be overclocked up to 18 MHz with some limitations.
The oscillator can be configured using the OSCCFG register. The oscillator frequency can be set to either 12 MHz or 18 MHz, and the oscillator mode can be set to either XTAL or RC.
The maximum current that can be sourced or sunk by the I/O pins of the P89LPC9103FTK,115 is 20 mA.
The UART on the P89LPC9103FTK,115 can be used by configuring the UART registers and using the UART interrupts. The UART can operate at baud rates up to 115200 bps.
The power consumption of the P89LPC9103FTK,115 depends on the operating frequency and the operating mode. In active mode, the power consumption is typically around 10 mA at 12 MHz, and in sleep mode, the power consumption is typically around 10 μA.
