FT60F11F-MRB from FMD Fremont Micro Devices, in a MSOP-10. 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	VDD	power_in	Positive supply input. Operating range 1.9-5.5 V (VDD >= 2.7 V required for 16 MHz operation).
2	OSC1/CLKI/PA7	bidirectional	Multiplexed pin: crystal/resonator input (OSC1), external clock input (CLKI, CMOS), or general-purpose PORTA bit 7 (PA7) with input-change interrupt and weak pull-up/pull-down.
3	OSC2/CLKO/PA6	bidirectional	Multiplexed pin: crystal/resonator output (OSC2), instruction clock output (CLKO; remapped to PC5 on E-revision silicon), or general-purpose PORTA bit 6 (PA6) with input-change interrupt and weak pull-up/pull-down.
4	[P1B]/ELVD/MCLRB/PA5	bidirectional	Multiplexed pin: remapped PWM1B output ([P1B]), external LVD analog input (ELVD), active-low external reset (MCLRB, with internal pull-up), or general-purpose PORTA bit 5 (PA5) with input-change interrupt.
5	P1B/PA4	bidirectional	Multiplexed pin: default PWM1B output (P1B), or general-purpose PORTA bit 4 (PA4) with input-change interrupt and weak pull-up/pull-down. Source/sink capability 8/31 mA.
6	PC5/P1A0	bidirectional	Multiplexed pin: general-purpose PORTC bit 5 (PC5) with weak pull-up/pull-down, or PWM1A0 output (P1A0). On E-revision devices this pin also carries the CLKO instruction-clock output. Source/sink capability 8/31 mA.
7	PA2/T0CKI/INT/[P1C]/BK0	bidirectional	Multiplexed pin: PORTA bit 2 (PA2) with input-change interrupt and weak pull-up/pull-down, Timer0 external clock input (T0CKI), external interrupt input (INT), remapped PWM1C output ([P1C]), or PWM brake input (BK0).
8	PA1/ISCPDAT	bidirectional	In-system programming / on-chip debug data pin (ISCPDAT), doubling as general-purpose PORTA bit 1 (PA1) with input-change interrupt and weak pull-up/pull-down.
9	PA0/ISCPCLK	bidirectional	In-system programming / on-chip debug clock pin (ISCPCLK), doubling as general-purpose PORTA bit 0 (PA0) with input-change interrupt and weak pull-up/pull-down.
10	GND	power_in	Negative supply / ground reference.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ft60f11f-mrb.step`	148 KB	You want the bare part, or you mark your own boards.
`ft60f11f-mrb-etched.step`	2.1 MB	You want the part with `FT60F11F-MRB` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 549 faces against 177 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
