XR22801IL32TR-F from MaxLinear, in a QFN-32-EP(5x5). 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 | VBUS_SENSE | input | VBUS sense input; in self-powered mode connect VBUS through a high-value divider (VBUS=5V, VBUS_SENSE=3.3V) decoupled by 0.1uF, used to disable the USBD+ pull-up when VBUS is absent, ignored in bus-powered mode. |
| 2 | REXT | input | Connect externally using a short trace to a 226 ohm 1% resistor to ground. |
| 3 | CAP1 | input | Connect externally to CAP2 and 3V3_OUT using a short trace. |
| 4 | GND | power_in | Power supply common, ground. |
| 5 | USBD- | bidirectional | USB port differential data negative. |
| 6 | USBD+ | bidirectional | USB port differential data positive. |
| 7 | VCC | power_in | 5.0V power supply input. |
| 8 | ETH_SPD | output | Ethernet 100 Mbps speed indicator, asserted high for 100 Mbps. |
| 9 | XTALOUT | output | Crystal or buffered clock output. |
| 10 | XTALIN | input | 25 MHz +/- 50 ppm crystal or external clock input. |
| 11 | 3V3_OUT | power_out | 3.3V output power; connect to CAP1 and CAP2 using a short trace and decouple with a minimum 4.7uF capacitor. |
| 12 | GND | power_in | Power supply common, ground. |
| 13 | ETH_TX- | output | Ethernet transmit data out negative. |
| 14 | ETH_TX+ | output | Ethernet transmit data out positive. |

| 16 | ETH_RX- | input | Ethernet receive data in negative. |
| 17 | E0/RI#/RWK#/G0 | bidirectional | Enhanced GPIO, UART Ring Indicator, remote wakeup, or general purpose IO; defaults to UART GPIO input. |
| 18 | E1/CD#/G1 | bidirectional | Enhanced GPIO, UART Carrier Detect, or general purpose IO; defaults to UART GPIO input. |
| 19 | ETH_LINK | output | Ethernet 10/100 activity indicator that toggles with activity. |
| 20 | CAP2 | input | Connect externally to CAP1 and 3V3_OUT using a short trace. |
| 21 | GND | power_in | Power supply common, ground. |
| 22 | GND | power_in | Power supply common, ground. |
| 23 | E6/RX/RWK# | bidirectional | Enhanced GPIO, UART RX data, or remote wakeup; defaults to UART RX data. |
| 24 | E7/TX | bidirectional | Enhanced GPIO or UART TX data; defaults to UART TX data. |
| 25 | E5/RTS#/RS485/G5 | bidirectional | Enhanced GPIO, UART Request to Send, auto-RS485 half-duplex enable, or general purpose IO; defaults to UART GPIO input except with CDC-ACM driver. |
| 26 | E4/CTS#/G4 | bidirectional | Enhanced GPIO, UART Clear to Send, or general purpose IO; defaults to UART GPIO input except with CDC-ACM driver. |
| 27 | LOW_PWR# | output | Asserted when it is not safe to draw the current requested from VBUS (suspend or not yet configured); default active low, polarity programmable via OTP. |
| 28 | GND | power_in | Power supply common, ground. |
| 29 | E2/DSR#/G2 | bidirectional | Enhanced GPIO, UART Data Set Ready, or general purpose IO; defaults to UART GPIO input. |
| 30 | E3/DTR#/G3 | bidirectional | Enhanced GPIO, UART Data Terminal Ready, or general purpose IO; defaults to UART GPIO input. |
| 31 | SCL | bidirectional | I2C master controller serial clock (open-drain); external pull-up resistor required. |
| 32 | SDA | bidirectional | I2C master controller data (open-drain); external pull-up resistor required. |
| 33 | CNTR_PAD | power_in | Center pad; must be connected to ground. |
