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 | CSN | input | SPI chip-select / enable input (active low). Has an internal pull-up (leakage spec references CSN internal pull-up). Digital input logic thresholds referenced to VDD (VIH ≥ 0.7*VDD, VIL ≤ 0.3*VDD). |+| 2 | HVPP | power_in | Dual-function pin. Accepts ~7.0-7.2 V during MTP (NVM) programming, and selects SPI vs. ABZ/UVW output mode during normal operation: tie to VDD for SPI mode, tie to GND for ABZ or UVW mode. Absolute max 8 V. |+| 3 | OUT | output | PWM angle-output pin. Push-pull digital output; PWM frequency is programmable, default 971.1 Hz (±8%), 12-bit absolute angle encoded as duty cycle. Max source/sink 20 mA. |+| 4 | VDD | power_in | Main supply pin, 3.3-5.0 V typical (3.0-5.5 V operating range, 6.5 V absolute max). Feeds an internal LDO that powers the AMR bridges and digital core. Typical Idd = 10 mA, max 15 mA. |+| 5 | A/U/MOSI/SDAT | bidirectional | Muxed I/O. Functions: incremental encoder A output (ABZ mode), commutation U output (UVW mode), SPI MOSI (4-wire SPI), or SDAT bidirectional data (3-wire SPI). Push-pull, ±20 mA max. |+| 6 | B/V/MISO | bidirectional | Muxed I/O. Functions: incremental encoder B output (ABZ mode), commutation V output (UVW mode), or SPI MISO (4-wire SPI). Unused in 3-wire SPI. Push-pull, ±20 mA max. |+| 7 | Z/W/SCK | bidirectional | Muxed I/O. Functions: incremental encoder Z index output (ABZ mode), commutation W output (UVW mode), or SPI clock input (3-wire or 4-wire SPI). Push-pull, ±20 mA max. |+| 8 | GND | power_in | Device ground / substrate return. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Magn Tek |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `MT6816CT-ACD-RCT-STD`+- `MT6816CT-ACD-RCT-STT`+- `MT6816CT-ACD-RCT-AKD`+- `MT6816CT-ACD-RCT-AKH`+- `MT6816CT-ACD-R`+- `MT6816CT-ACD-RCT-ACE`+- `MT6816CT-ACD-RCT-A9D`+- `MT6816CT-ACD-RCT-A400`+- `MT6816CT-ACD-RCT-A200`+- `MT6816CT-ACD-RCT-A100`+- `MT6816CT-ACD-RCT-U7D`+- `MT6816CT-ACD-RCT-U5D`++## CAD (KiCad official)++- Symbol: `MT6816CT-ACD-R`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Magn Tek datasheet](docs/mt6816ct-acd-r-datasheet.pdf) (30 pp, sha256 `74b66b99a0d6b0e4`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
