PIC16(L)F145X

1.2 Pin Utilization

Five pins are needed for ICSP™ programming. It is

recommended to use the pins listed in Table 1-1. For

PIC18F1XK50 legacy designs refer to Section 4.2.1

“Legacy ICSP Pinout Programming”.

Legend:

Note 1:

I = Input, O = Output, P = Power

The programming high voltage is internally generated. To activate the Program/Verify mode, high voltage needs to be

applied to MCLR input. Since the MCLR is used for a level source, MCLR does not draw any significant current.
