SMSC DS – LPC47N237
The LPC47N237 has two power planes: VCC and VTR. It contains 24 MHz crystal pins and 24 MHz clock
output.
3.3 Volt Operation / 5 Volt Tolerance
The LPC47N237 is a 3.3 Volt part. It is intended solely for 3.3V applications. Non-LPC bus pins are 5V
tolerant; that is, the input voltage is 5.5V max, and the I/O buffer output pads are backdrive protected.
The LPC interface pins are 3.3 V only. These signals meet PCI DC specifications for 3.3V signaling.
These pins are:
The input voltage for all other pins is 5.5V max. These pins include all non-LPC Bus pins and the following
pins:
