Specifications of LPC47N227TQFP

• Lead Free Status / RoHS Status: Not Compliant

The LPC47N227 provides a set of flexible Input/Output control functions to the system designer
through the 29 independently programmable General Purpose I/O pins (GPIO). The GPIO pins can
perform basic I/O and many of them can be individually enabled to generate an SMI and a PME.
GPIO Pins
The following pins include GPIO functionality as defined in the table below.
Note 1: These pins have input buffers into the wakeup logic that are powered by VTR.
