FT60F023-RB from FMD Fremont Micro Devices, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	PA1/C1IN-/ICSPDAT	bidirectional	PORTA bit 1: general-purpose I/O with interrupt-on-change and configurable weak pull-up. Alternate functions: Comparator1 inverting input (C1IN-, analog) and ICSP programming/debug data line (ICSPDAT, Fmax=6 MHz).
2	PA7/OSC1/CLKI	bidirectional	PORTA bit 7: general-purpose I/O with interrupt-on-change and configurable weak pull-up. Alternate functions: crystal/resonator input OSC1 or external clock input CLKI depending on the selected oscillator mode in the configuration word.
3	PA6/OSC2/CLKO	bidirectional	PORTA bit 6: general-purpose I/O with interrupt-on-change and configurable weak pull-up. Alternate functions: crystal/resonator output OSC2 or test clock output CLKO depending on the configured oscillator mode.
4	VDD	power_in	Positive supply voltage. Operating range 2.0-5.5 V (Fsys<=8 MHz) or 2.7-5.5 V for Fsys=16 MHz. Decouple to VSS locally.
5	PC7	bidirectional	PORTC bit 7: general-purpose CMOS I/O with Schmitt-trigger input.
6	PC6	bidirectional	PORTC bit 6: general-purpose CMOS I/O with Schmitt-trigger input.
7	PC5	bidirectional	PORTC bit 5: general-purpose CMOS I/O with Schmitt-trigger input.
8	PC4/C2OUT	bidirectional	PORTC bit 4: general-purpose CMOS I/O. Alternate function: Comparator2 output (C2OUT, CMOS) when C2OUT routing is enabled.
9	PC3	bidirectional	PORTC bit 3: general-purpose CMOS I/O with Schmitt-trigger input.
10	PC2	bidirectional	PORTC bit 2: general-purpose CMOS I/O with Schmitt-trigger input.
11	PC1/C2IN-	bidirectional	PORTC bit 1: general-purpose CMOS I/O. Alternate function: Comparator2 inverting input (C2IN-, analog).
12	PC0/C2IN+	bidirectional	PORTC bit 0: general-purpose CMOS I/O. Alternate function: Comparator2 non-inverting input (C2IN+, analog).
13	VSS	power_in	Ground / negative supply return (0 V reference).
14	PA4/ATEST0	bidirectional	PORTA bit 4: general-purpose I/O with interrupt-on-change and configurable weak pull-up. Alternate function: analog test pin 0 (ATEST0) for internal factory test only.
15	PA2/T0CKI/INT/C1OUT	bidirectional	PORTA bit 2: general-purpose I/O with interrupt-on-change and configurable weak pull-up. Alternate functions: Timer0 external clock input (T0CKI, Fmax=4 MHz), external interrupt input (INT), and Comparator1 output (C1OUT, CMOS).
16	PA0/C1IN+/ICSPCLK	bidirectional	PORTA bit 0: general-purpose I/O with interrupt-on-change and configurable weak pull-up. Alternate functions: Comparator1 non-inverting input (C1IN+, analog) and ICSP programming/debug clock (ICSPCLK, Fmax=6 MHz).
