PIC18F26K83 – 28-pin SPDIP

Notes

• Pin 1 (VPP/MCLR/RE3) serves as Master Clear input, programming voltage input, and also functions as RE3 I/O pin.
• Pins 8 and 19 are both VSS (ground); pin 20 is VDD (supply voltage).
• RB6 and RB7 are dedicated to In-Circuit Serial Programming (ICSP) but also function as general-purpose I/O.
• Peripheral function assignments (analog, timer, PWM, etc.) are detailed in Table 3 of the datasheet.
• The 28-pin QFN variant uses the same pin names and functions as the SPDIP package shown here.
