XR22801IL32TR-F

MaxLinear · USB ICs · QFN-32-EP(5x5)

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.
15 ETH_RX+ input Ethernet receive data in 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.
