Product details
Overview
PD69220R-035200-TR from Microchip Technology is a Generation 6 Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller supporting IEEE 802.3af, 802.3at, and 802.3bt standards plus HDBaseT (PoH), delivering up to 45 W per port across up to 48 logical ports in 2-pair or 4-pair configurations. It integrates SPI, I2C, and UART host interfaces, features per-port power limiting, legacy PD detection, and perpetual PoE for firmware upgrades without power interruption.
For engineers reviewing the PD69220R-035200-TR datasheet, PD69220R-035200-TR pinout, PD69220R-035200-TR application, or PD69220R-035200-TR equivalent, key selection criteria include IEEE 802.3bt compliance, 32-pin LGA 5 mm × 5 mm package compatibility with PD69200 layouts, I2C/UART interface configurability via analog address pin, and support for dynamic/static/class-based power management modes.
Technical Context
The PD69220R-035200-TR implements a dual-mode PoE control architecture: it manages up to 48 logical ports using configurable port matrix mapping-each logical port built from one or two physical ports-and communicates with PD69208T4/PD69204T4/PD69208M PoE managers via 1 MHz SPI slave interface. Its firmware is pre-programmed, field-upgradeable, and vendor-agnostic, enabling standalone operation or host-coordinated control.
Hardware-level features include active-low system OK output (xSys_OK/LED), dedicated disable port input (xDISABLE_PORTS), interrupt signaling (xINT_OUT), and LED stream control (xLED_OE, xLED_CS, xLED_LATCH2). The device uses an internal 1.2 V core supply (VDD_CORE) and 3.3 V main supply (VDD/VDDA), with thermal resistance θJA = 65.0 °C/W and θJC = 21.5 °C/W for its laminated QFN (LGA) package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IEEE Standards | Compliant with 802.3af/at/bt and HDBaseT (PoH); enables full Type 3/4 PoE+ and PoE++ deployment. |
| Max Logical Ports | 48 ports; supports flexible 2-pair or 4-pair logical port construction for scalable switch designs. |
| Per-Port Power Limit | Configurable up to 45 W; automatic disconnection on limit violation ensures safe operation and PD protection. |
| Host Interface | I2C (400 kHz, clock stretch required) or UART (19.2 kbps, 8N1); selected by analog voltage on I2C_ADDR_MEAS pin. |
| Operating Temp | –40 °C to +85 °C; qualified for industrial Ethernet infrastructure environments. |
| Supply Voltages | VDD/VDDA = 3.0–3.63 V; VDD_CORE = 1.2 V; decoupling requires 1 µF capacitor on VDD_CORE to VSSD. |
| ESD Rating | HBM ±2000 V, CDM ±500 V; meets JESD22 Class 2/Class 1 for robust board-level handling. |
Pinout & Package
PD69220R-035200-TR is housed in a 32-pin laminated QFN (Land Grid Array), also referred to as LGA, measuring 5 mm × 5 mm with exposed thermal pad (ePAD) requiring connection to VSSA for thermal performance. This package is mechanically compatible with PCB footprints designed for PD69200 but uses a distinct solder paste stencil profile.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Reserved (UART) | Reserved UART function; leave unconnected. |
| 2 | Reserved (UART) | Reserved UART function; pull up to 3.3 V via 10 kΩ. |
| 32 | xSys_OK/LED | Active-low system validity indicator; drives LED or host alert when system is operational. |
| 31 | xDISABLE_PORTS | Active-low global shutdown input; asserts low to disable all PoE ports simultaneously. |
| 22 | I2C_ADDR_MEAS | Analog input selecting I2C address (0x04–0x3C) or UART mode via external resistor divider. |
| 11 | UART0_RX | UART receive input from host; 19.2 kbps, 8N1, requires external pull-up. |
| 12 | UART0_TX | UART transmit output to host; carries 15-byte protocol telemetry and replies. |
| 20 | I2C0_SDA | Bidirectional I2C data line; supports 15-byte message protocol with external pull-up. |
| 21 | I2C0_SCL | I2C clock input from host; requires clock stretch support and external pull-up. |
| 25 | xINT_OUT | Active-low interrupt output signaling port on/off, fault, or voltage out-of-range events. |
| 27 | xLED_LATCH2 | Active-low latch signal for external LED stream; synchronizes LED state updates. |
| ePAD | Thermal Pad | Must be connected to VSSA with sufficient copper mass for thermal dissipation (θJA = 65.0 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Perpetual PoE | Maintains PoE power delivery during host firmware upgrade or reset-eliminates service interruption in managed switches. |
| Legacy PD Detection | Supports pre-standard powered devices via reduced-capacitance detection on each port-ensures backward compatibility. |
| Fast PoE Boot | Enables rapid port power-up independent of host initialization-reduces system boot time in time-sensitive deployments. |
| Port Power Management | Three configurable modes (Class/LLDP, Dynamic, Static) allow precise power allocation aligned with network traffic and PD class. |
| LED Stream Interface | Dedicated SPI-compatible signals (xLED_OE, xLED_CS, xLED_LATCH2) drive external LED arrays for real-time port status visualization. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PoE PSE controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PD69210D1VVVV2SS3-TR | Identical feature set and firmware but 32-pin QFN (not LGA); different pinout (e.g., I2C_ADDR_MEAS on Pin 13 vs. Pin 22). | Requires PCB redesign due to non-pin-compatible layout; same thermal profile (θJA = 40.9 °C/W) but superior junction-to-ambient performance. | Select when thermal budget is critical and board layout allows QFN footprint. |
| PD69200D1VVVV2SS3-TR | Generation 5 controller; lacks IEEE 802.3bt and HDBaseT (PoH) support; no perpetual PoE or fast PoE boot. | Suitable only for legacy 802.3af/at designs; cannot replace PD69220R-035200-TR in new 802.3bt-compliant systems. | Choose only for cost-sensitive brownfield upgrades where 802.3bt is not required. |
Compared with PD69210D1VVVV2SS3-TR, PD69220R-035200-TR trades lower thermal resistance for LGA mechanical compatibility with PD69200 layouts; compared with PD69200D1VVVV2SS3-TR, it adds essential 802.3bt and PoH capabilities required for next-generation infrastructure.

FAQ
What IEEE PoE standards does the PD69220R-035200-TR support?
The PD69220R-035200-TR supports IEEE 802.3af (Type 1), 802.3at (Type 2), and 802.3bt (Type 3/4) standards, plus HDBaseT (Power over HDBaseT, PoH). It delivers up to 45 W per logical port and manages up to 48 ports in 2-pair or 4-pair configurations. All compliance is implemented in firmware and verified per Microchip's DS00003424A datasheet.
Is the PD69220R-035200-TR pin-compatible with the PD69200 series?
The PD69220R-035200-TR is not pin-compatible with the PD69200, but its top-layer copper footprint matches PD69200 layouts-enabling reuse of existing PCBs with only stencil and assembly process adjustments. Critical differences include I2C_ADDR_MEAS on Pin 22 (vs. Pin 13 on PD69210) and LGA-specific thermal pad requirements.
How is communication configured between the host and PD69220R-035200-TR?
Communication with the PD69220R-035200-TR is configurable via I2C (400 kHz, 7-bit address, clock stretch required) or UART (19.2 kbps, 8N1), selected by applying a specific voltage to the I2C_ADDR_MEAS pin (Pin 22). Both interfaces use a standardized 15-byte protocol for commands, telemetry, and status reporting as defined in Microchip's PD69210 Communication Protocol User Guide.
What is the thermal performance of the PD69220R-035200-TR package?
The PD69220R-035200-TR uses a 32-pin laminated QFN (LGA) package with θJA = 65.0 °C/W and θJC = 21.5 °C/W. Its ePAD must be connected to VSSA with adequate copper area and thermal vias. This thermal profile differs from the PD69210's QFN (θJA = 40.9 °C/W) and reflects the LGA's higher ambient resistance-designers should verify junction temperature under worst-case 48-port load conditions.
Does the PD69220R-035200-TR support firmware updates in the field?
Yes, the PD69220R-035200-TR supports field-upgradeable firmware via its I2C or UART interface. Firmware version is encoded in the ordering part number, and updates are performed using Microchip's Configuration Tool and Serial Communication Protocol Guide. The device retains full PoE functionality-including perpetual PoE-during update sequences.
