RD2/PSP2 RD2 PSP2 21 40 40 I/O I/O ST/TTL(3) Digital I/O. Parallel Slave Port data. RD3/PSP3 RD3 PSP3 22 41 41 I/O I/O ST/TTL(3) Digital I/O. Parallel Slave Port data. RD4/PSP4 RD4 PSP4 27 2 2 I/O I/O ST/TTL(3) Digital I/O. Parallel Slave Port data. RD5/PSP5 RD5 PSP5 28 3 3 I/O I/O ST/TTL(3) Digital I/O. Parallel Slave Port data. RD6/PSP6 RD6 PSP6 29 4 4 I/O I/O ST/TTL(3) Digital I/O. Parallel Slave Port data. RD7/PSP7 RD7 PSP7 30 5 5 I/O I/O ST/TTL(3) Digital I/O. Parallel Slave Port data. PORTE is a bidirectional I/O port. RE0/RD/AN5 RE0 RD AN5 825 25 I/O I I ST/TTL(3) Digital I/O. Read control for Parallel Slave Port. Analog input 5. RE1/WR/AN6 RE1 WR AN6 926 26 I/O I I ST/TTL(3) Digital I/O. Write control for Parallel Slave Port. Analog input 6. RE2/CS/AN7 RE2 CS AN7 10 27 27 I/O I I ST/TTL(3) Digital I/O. Chip select control for Parallel Slave Port. Analog input 7. VSS — 31 — P — Analog ground reference. VSS 12, 31 6, 30 6, 29 P — Ground reference for logic and I/O pins. VDD — 8 — P — Analog positive supply. VDD 11, 32 7, 28 7, 28 P — Positive supply for logic and I/O pins. NC — 13, 29 12, 13, 33, 34 — — These pins are not internally connected. These pins should be left unconnected. TABLE 1-3: PIC16F747 AND PIC16F777 PINOUT DESCRIPTION (CONTINUED) Pin Name PDIP Pin # QFN Pin # TQFP Pin # I/O/P Type Buffer Type Description Legend: I = input O = output I/O = input/output P = power — = Not used TTL = TTL input ST = Schmitt Trigger input Note 1: This buffer is a Schmitt Trigger input when configured as an external interrupt. 2: This buffer is a Schmitt Trigger input when used in Serial Programming mode. 3: This buffer is a Schmitt Trigger input when configured as a general purpose I/O and a TTL input when used in the Parallel Slave Port mode (for interfacing to a microprocessor bus). 4: This buffer is a Schmitt Trigger input when configured in RC Oscillator mode and a CMOS input otherwise. 5: Pin location of CCP2 is determined by the CCPMX bit in Configuration Word Register 1. |
