DP83TD510ERHBR from Texas Instruments, in a HVQFN-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 DVDD power_in 1.0V digital supply; short to CEXT (pin 2) for single-supply operation, or connect an external 1.0V supply for ultra-low-power dual-supply operation (recommended 0.90 to 1.1V).
2 CEXT passive External capacitor for the internal LDO; connect a 0.01uF capacitor and short to pin 1 for single supply, leave unconnected for dual supply.
3 VDDA power_in Analog supply: 3.3V (3.0 to 3.6V) supports 2.4V p2p and 1V p2p modes, 1.8V (1.62 to 1.98V) supports 1V p2p mode only.
4 TX+ output Differential transmit output (PMD) configured as 2.4V p2p or 1V p2p according to PHY configuration and auto-negotiation.
5 RX+ input Differential receive input that is automatically configured to accept 2.4V p2p or 1V p2p mode.
6 RX- input Differential receive input that is automatically configured to accept 2.4V p2p or 1V p2p mode.
7 TX- output Differential transmit output (PMD) configured as 2.4V p2p or 1V p2p according to PHY configuration and auto-negotiation.
8 GPIO2/Strap10 bidirectional Register-configurable GPIO with forced PU/PD strap (Strap10) that selects termination: 0 = receiver with 50 ohm tap resistor (recommended), 1 = tap resistor below 40 ohm; internal pull-down in all states.
9 XO output Crystal output for the reference clock; used only with a crystal and left floating when a CMOS oscillator drives XI.
10 XI/50MHzIn input Crystal/oscillator input clock: 25MHz +/-50ppm for MII and RMII master, 50MHz +/-50ppm CMOS oscillator for RMII slave.
11 MDIO bidirectional Bidirectional management data I/O that requires an external 2.2k to 4.0k ohm pull-up resistor.
12 MDC input Management data clock for MDIO serial management, asynchronous to MAC clocks, maximum 1.75MHz.
13 RX_D3/Strap1 bidirectional Receive data bit 3 (nibble RX_D[3:0] in MII mode, synchronous to RX_CLK); latched at reset as PHY address bit 3 strap, internal pull-down.
14 RX_D2/Strap2 bidirectional Receive data bit 2 (MII/RGMII); strap selects pin 18 as CRS_DV (0, default) or RX_DV (1, RMII repeater/media converter), internal pull-down.
15 RX_D1/Strap3 bidirectional Receive data bit 1 (RX_D[1:0] in RMII); strap with Strap8 selects MAC mode (MII, RMII master, RGMII, RMII slave), internal pull-down.
16 RX_D0 bidirectional Receive data bit 0 (RX_D[1:0] in RMII); latched at reset as PHY address bit 2 strap, internal pull-down.
17 VDDIO power_in I/O supply of 3.3V, 2.5V or 1.8V (1.62 to 3.6V across options); see decoupling requirements in the application section.
18 RX_DV/CRS_DV/Strap5 bidirectional Receive data valid (MII) or CRS_DV (RMII), RGMII RX_CTRL; strap selects CLKOUT 25MHz (0) or LED_1 (1) on pin 30, internal pull-down.
19 RX_CLK/50MHz_RMII_M bidirectional MII/RGMII receive clock (2.5MHz at 10Mbps) and 50MHz reference clock output in RMII master mode; unused input with pull-down in RMII slave mode.
20 RX_ER/Strap6 bidirectional Receive error indication in MII and RMII modes, unused in RGMII; latched at reset as PHY address bit 1 strap, internal pull-down.
21 PWDN/INT_N bidirectional Active-low power-down (default) or interrupt pin; open-drain output with weak internal 9.5k ohm pull-up, may need an external pull-up.
22 TX_CLK bidirectional MII transmit clock output (2.5MHz at 10Mbps) or RGMII transmit clock input from MAC (2.5MHz at 10Mbps); unused in RMII.
23 TX_EN input Transmit enable (TX_CTRL in RGMII) indicating valid data on TX_D[3:0] (MII) or TX_D[1:0] (RMII); active high with internal pull-down.
24 TX_D0 input Transmit data bit 0 from the MAC, synchronous to TX_CLK (MII), CLKOUT50M (RMII master) or the reference clock (RMII slave); internal pull-down.
25 TX_D1 input Transmit data bit 1 from the MAC, synchronous to TX_CLK (MII), CLKOUT50M (RMII master) or the reference clock (RMII slave); internal pull-down.
26 TX_D2 input Transmit data bit 2 from the MAC (MII and RGMII nibble TX_D[3:0]); internal pull-down.
27 TX_D3 input Transmit data bit 3 from the MAC (MII and RGMII nibble TX_D[3:0]); internal pull-down.
28 LED_2/TX_ER/Strap7 bidirectional LED_2 by default (on when link is 10M short reach), configurable as GPIO or TX_ER; Strap7 reach selection: 0 = 2.4V and 1V p2p, 1 = 1V p2p only.
29 LED_0/Strap8 bidirectional Link/activity LED (on for link, blinks on TX/RX activity), also usable as GPIO; Strap8 with Strap3 selects MAC mode.
30 CLKOUT/LED_1 output Provides 25MHz reference CLKOUT by default, configurable as LED_1 (on when link is 10M long reach) by strap or register; clock is unaffected by reset when CLK_OUT.
31 RST_N input Active-low reset input; hold low at least 25us to reset, which rescans straps and resets all registers to defaults; internal pull-up.
32 GPIO1/Strap9 bidirectional General-purpose input or output; latched at reset as PHY address bit 0 strap, internal pull-down.
33 EP power_in Exposed die attach pad (DAP) connected to GND.
