Objective data sheet Rev. 2 — 27 May 2011 9 of 117 NXP Semiconductors LPC178x/7x 32-bit ARM Cortex-M3 microcontroller 6.2 Pin description I/O pins on the LPC178x/7x are 5V tolerant and have input hysteresis unless otherwise indicated in the table below. Crystal pins, power pins, and reference voltage pins are not 5V tolerant. In addition, when pins are selected to be ADC inputs, they are no longer 5V tolerant and the input voltage must be limited to the voltage at the ADC positive reference pin (VREFP). All port pins Pn[m] are multiplexed, and the functions appear in their order defined in the FUNC bits of the corresponding IOCON register. Each port pin can support up to eight multiplexed functions. IOCON register FUNC values which are reserved are noted as “R” in the pin configuration table Fig 4. Pin configuration (TFBGA180) Fig 5.
