PIC16F1936-I from Microchip Tech, in a SSOP-28-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RE3/MCLR/VPP input General-purpose input-only pin RE3; when MCLRE is set it functions as the MCLR master reset with an internal weak pull-up, and VPP is the high-voltage programming input.
2 RA0/AN0/C12IN0-/C2OUT/SRNQ/SS/VCAP/SEG12 bidirectional General-purpose I/O with ADC input AN0, comparator C1/C2 inverting input C12IN0-, LCD SEG12, and alternate outputs C2OUT and SRNQ, input SS, and VCAP regulator filter capacitor selectable via APFCON or CONFIG2.
3 RA1/AN1/C12IN1-/SEG7 bidirectional General-purpose I/O with ADC input AN1, comparator inverting input C12IN1-, and LCD analog output SEG7.
4 RA2/AN2/C2IN+/VREF-/DACOUT/COM2 bidirectional General-purpose I/O with ADC input AN2, ADC negative reference VREF-, comparator C2 non-inverting input C2IN+, DAC reference output DACOUT, and LCD analog output COM2.
5 RA3/AN3/C1IN+/VREF+/COM3/SEG15 bidirectional General-purpose I/O with ADC input AN3, ADC positive reference VREF+, comparator C1 non-inverting input C1IN+, and LCD outputs COM3/SEG15; on this device COM3 and SEG15 share the pin, so SEG15 is unavailable in 1/4 multiplex mode.
6 RA4/C1OUT/CPS6/T0CKI/SRQ/CCP5/SEG4 bidirectional General-purpose I/O with comparator C1 output C1OUT, capacitive sensing input CPS6, Timer0 clock input T0CKI, SR latch output SRQ, CCP5 (28-pin device), and LCD output SEG4.
7 RA5/AN4/C2OUT/CPS7/SRNQ/SS/VCAP/SEG5 bidirectional General-purpose I/O with ADC input AN4, comparator C2 output C2OUT, capacitive sensing input CPS7, SR latch output SRNQ, SS input, VCAP regulator filter capacitor, and LCD output SEG5, with alternate functions selectable via APFCON or CONFIG2.
8 VSS power_in Reference ground for the device.
9 RA7/OSC1/CLKIN/SEG2 bidirectional General-purpose I/O; OSC1 crystal/resonator input in LP/XT/HS modes, CLKIN external clock input in EC mode, RC oscillator connection in RC mode, and LCD output SEG2.
10 RA6/OSC2/CLKOUT/VCAP/SEG1 bidirectional General-purpose I/O; OSC2 crystal/resonator output in LP/XT/HS modes, CLKOUT FOSC/4 output when enabled by CLKOUTEN, VCAP regulator filter capacitor when selected by VCAPEN, and LCD output SEG1.
11 RC0/T1OSO/T1CKI/P2B bidirectional General-purpose I/O; Timer1 oscillator output T1OSO, Timer1 clock input T1CKI (Schmitt trigger), and PWM output P2B.

13 RC2/CCP1/P1A/SEG3 bidirectional General-purpose I/O; CCP1 capture/compare/PWM1, PWM output P1A, and LCD analog output SEG3.
14 RC3/SCK/SCL/SEG6 bidirectional General-purpose I/O; MSSP SPI clock SCK, I2C clock SCL (open-drain, I2C levels), and LCD analog output SEG6.
15 RC4/SDI/SDA/T1G/SEG11 bidirectional General-purpose I/O; MSSP SPI data input SDI, I2C data SDA (open-drain), Timer1 gate input T1G, and LCD analog output SEG11.
16 RC5/SDO/SEG10 bidirectional General-purpose I/O; MSSP SPI data output SDO (CMOS) and LCD analog output SEG10.
17 RC6/TX/CK/CCP3/P3A/SEG9 bidirectional General-purpose I/O; EUSART asynchronous transmit TX, synchronous clock CK, CCP3 capture/compare/PWM3 and PWM output P3A (28-pin device), and LCD analog output SEG9.
18 RC7/RX/DT/P3B/SEG8 bidirectional General-purpose I/O; EUSART asynchronous receive RX, synchronous data DT, PWM output P3B (28-pin device), and LCD analog output SEG8.
19 VSS power_in Reference ground for the device.
20 VDD power_in Positive supply voltage; 1.8 V to 5.5 V for PIC16F193X (the -I part is not the low-power LF variant, which is 1.8 V to 3.6 V).
21 RB0/AN12/CPS0/CCP4/SRI/INT/SEG0 bidirectional General-purpose I/O with individually controlled interrupt-on-change and weak pull-up; also ADC input AN12, capacitive sensing CPS0, CCP4, SR latch input SRI, external interrupt INT, and LCD output SEG0.
22 RB1/AN10/C12IN3-/CPS1/P1C/VLCD1 bidirectional General-purpose I/O with interrupt-on-change and weak pull-up; also ADC input AN10, comparator inverting input C12IN3-, capacitive sensing CPS1, PWM output P1C, and LCD analog input VLCD1.
23 RB2/AN8/CPS2/P1B/VLCD2 bidirectional General-purpose I/O with interrupt-on-change and weak pull-up; also ADC input AN8, capacitive sensing CPS2, PWM output P1B, and LCD analog input VLCD2.
