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/AN1/C1IN-/ISPDAT | bidirectional | PORTA bit 1 general-purpose digital I/O with weak pull-up. Alternate functions: ADC analog input channel AN1, comparator 1 inverting input C1IN-, and ISP programming data line (ISPDAT). Source/sink capability 30 mA / 23 mA at VDD=5 V. |+| 2 | GND | power_in | Device ground reference (0 V). Common return for VDD, all I/O drivers, ADC and comparator analog blocks. |+| 3 | PC1/AN5/C2IN-/P1E/INT | bidirectional | PORTC bit 1 general-purpose digital I/O with weak pull-up/pull-down. Alternate functions: ADC channel AN5, comparator 2 inverting input C2IN-, ECCP enhanced-PWM output P1E, and external edge interrupt input INT. Source/sink 30 mA / 23 mA at VDD=5 V. |+| 4 | PA6/OSC2/T1G/CLKO | bidirectional | PORTA bit 6 general-purpose digital I/O with weak pull-up. Alternate functions: crystal/resonator output OSC2 (LP/XT mode), Timer1 gate input T1G, and system-clock output CLKO. Source/sink 30 mA / 23 mA at VDD=5 V. |+| 5 | VDD | power_in | Positive supply input. Operating range 2.0 V (VPOR) to 5.5 V; POR auto-adjusts down to 1.7 V once running. Bypass with local decoupling to GND. |+| 6 | PA0/AN0/C1IN+/ISPCLK | bidirectional | PORTA bit 0 general-purpose digital I/O with weak pull-up. Alternate functions: ADC channel AN0, comparator 1 non-inverting input C1IN+, and ISP programming clock (ISPCLK). Source/sink 30 mA / 23 mA at VDD=5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | FMD Fremont Micro Devices |+| Package | SOT-23-6 |+| Category | MCU |+| Pins | 6 |++## Ordering variants++- `FT61F020-URT`+- `FT61F020-URTFT61F020-URB`+- `FT61F020-URTFT61F020-UGT`+- `FT61F020-URTFT61F020-UGB`+- `FT61F020-URTFT61F021A-RB`+- `FT61F020-URTFT61F021A-RT`+- `FT61F020-URTFT61F021B-RB`+- `FT61F020-URTFT61F021B-RT`+- `FT61F020-URTFT61F021A-DRB`+- `FT61F020-URTFT61F021A-DRT`+- `FT61F020-URTFT61F021B-DRB`+- `FT61F020-URTFT61F021B-DRT`+- `FT61F020-URTFT61F02F-MRB`+- `FT61F020-URTFT61F02F-MRT`+- `FT61F020-URTFT61F02FA-MRB`+- `FT61F020-URTFT61F02FA-MRT`+- `FT61F020-URTFT61F022A-RB`+- `FT61F020-URTFT61F022A-RT`+- `FT61F020-URTFT61F022B-RB`+- `FT61F020-URTFT61F022B-RT`+- `FT61F020-URTFT61F022A-DRB`+- `FT61F020-URTFT61F022A-DRT`+- `FT61F020-URTFT61F023-RB`+- `FT61F020-URTFT61F023-RT`+- `FT61F020-URTFT61F023-DRB`+- `FT61F020-URTFT61F023-DRT`++## CAD (KiCad official)++- Symbol: `FT61F020-URT`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [FMD Fremont Micro Devices datasheet](docs/ft61f020-urt-datasheet.pdf) (115 pp, sha256 `c673e26d7cd0b941`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
