Product details
Overview
PD69210R-022620 from Microchip Technology is a Generation 6 IEEE 802.3af/at/bt and HDBaseT-compliant PoE Power Sourcing Equipment (PSE) controller for Ethernet switches, supporting up to 48 logical ports with 45W per 2-pair port, operating from 3.0–3.63V supply at –40°C to +85°C ambient.
For engineers reviewing the PD69210R-022620 datasheet, PD69210R-022620 pinout, PD69210R-022620 application, or PD69210R-022620 equivalent, key selection considerations include I²C/UART interface configurability, per-port power limiting, legacy PD detection, Fast PoE boot timing, and thermal performance in 5 mm × 5 mm QFN packaging.
Technical Context
The PD69210R-022620 implements a firmware-based PSE control architecture built on the SAM D21 core, enabling standalone operation or host-coordinated management via 15-byte I²C or UART protocol at 19.2 kbps. It supports three power management modes-Class (LLDP), Dynamic, and Static-and integrates SPI communication with PoE managers (e.g., PD69208T4) at 1 MHz.
Its hardware design includes dedicated pins for system-level coordination: xDISABLE_PORTS (active-low global port shutdown), xSys_OK (active-low system validity indicator), xINT_OUT (event-driven interrupt output), and configurable I²C address selection via analog input I2C_ADDR_MEAS, ensuring flexible integration into multi-controller PoE systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IEEE Standards | Complies with 802.3af, 802.3at, 802.3bt, and HDBaseT (PoH) - enables full backward compatibility and high-power delivery up to 90W per 4-pair port. |
| Logical Ports | Supports up to 48 logical ports - allows scalable switch designs from 8- to 48-port PoE systems using 2-pair or 4-pair configurations. |
| Supply Voltage | 3.0 V to 3.63 V - compatible with standard 3.3 V rail; requires separate 1.2 V core (VDD_CORE) and analog (VDDA) supplies. |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade Ethernet infrastructure equipment including managed switches and PoE injectors. |
| Package | 32-pin QFN, 5 mm × 5 mm - surface-mount package with exposed thermal pad (ePAD) connected to VSSA for junction-to-ambient θJA = 40.9°C/W. |
| Communication | I²C or UART (19.2 kbps, 8N1) - dual-interface flexibility; I²C requires clock stretch support; UART uses pull-up on RX line. |
| Power Management | Per-port configurable limit + automatic disconnect - prevents overcurrent faults without host intervention; supports Class, Dynamic, and Static allocation modes. |
Pinout & Package
PD69210R-022620 is housed in a 32-pin, 5 mm × 5 mm plastic QFN package with exposed thermal pad (ePAD). The ePAD must be connected to VSSA with sufficient copper mass for thermal performance. Pin 1 is located at top-left corner of top view; pin numbering proceeds counterclockwise.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Reserved UART | Leave open; unused UART function; no connection required. |
| 3 | xSys_OK/LED | Active-low system validity output; drives LED or host GPIO to indicate operational readiness. |
| 4 | xDISABLE_PORTS | Active-low global port disable; asserts low to shut down all PoE ports immediately. |
| 5–8 | ESPI_MISO/SCK/xCS/MOSI | SPI interface to PoE manager ICs (e.g., PD69208T4); 1 MHz clock, active-low chip select, bidirectional data flow. |
| 13 | I2C_ADDR_MEAS | Analog input determining I²C address or UART mode; voltage divider sets address (0x4–0x3C) or selects UART. |
| 15–16 | UART0_TX/RX | Full-duplex UART interface at 19.2 kbps; TX outputs telemetry, RX receives commands; RX requires 10 kΩ pull-up. |
| 21–22 | I2C0_SDA/SCL | Bidirectional I²C interface; SCL requires host clock stretch support; both lines require pull-ups per AN3361. |
| 24 | xI2C_MESSAGE_READY | Active-low handshake signal indicating ready I²C response; host polls this pin before initiating read cycle. |
| 25 | xINT_OUT | Active-low interrupt output signaling port-on, port-fault, voltage-out-of-range, or device fault events. |
| 26 | xRESET | Active-low reset input; also driven low by controller during self-reset (100 µs pulse). |
| ePAD | Thermal Ground | Must connect to VSSA; critical for thermal dissipation; requires ≥1 cm² copper area for θJA compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Fast PoE | Enables rapid port power-up independent of host initialization - reduces system boot time for time-sensitive applications like security cameras. |
| Perpetual PoE | Maintains powered state during host firmware upgrade or reset - ensures uninterrupted power to connected PDs (e.g., VoIP phones, access points). |
| Legacy Detection | Supports pre-standard PDs via reduced-capacitance detection per port - preserves compatibility with older 802.3af-class devices. |
| LED Stream Interface | Dedicated SPI-based LED control (xLED_OE, xLED_CS, xLED_LATCH2) - enables direct drive of status LEDs without host CPU involvement. |
| Port Power Limiting | Configurable per-port wattage cap with automatic disconnection on exceedance - eliminates need for external current monitoring circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PoE PSE controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PD69220D1VVVV2SS3 | Different pinout (32-pin LGA vs. QFN); identical feature set and firmware; higher θJA (65.0°C/W) due to package construction. | Requires PCB redesign or footprint adaptation; suitable where LGA layout or pin-compatible migration from PD69200 is needed. | Select PD69220 only when leveraging its LGA package compatibility with legacy PD69200 layouts or requiring alternate thermal path design. |
| PD69200 | Previous-generation controller; lacks Fast PoE, Perpetual PoE, and HDBaseT support; no I²C address selection via analog input. | Not suitable for new 802.3bt or HDBaseT designs; limited to 802.3af/at applications with simpler power management. | PD69210R-022620 replaces PD69200 in all new designs requiring enhanced features, higher port count, or future-proof standards compliance. |

FAQ
What is the primary function of the PD69210R-022620 in a PoE system?
The PD69210R-022620 serves as a Power Sourcing Equipment (PSE) controller that manages power delivery, detection, classification, and fault protection across up to 48 logical Ethernet ports. It coordinates with PoE managers (e.g., PD69208T4) to implement IEEE 802.3af/at/bt and HDBaseT standards, and it operates either autonomously or under host control via I²C or UART. Its firmware is pre-programmed and field-upgradeable.
Does the PD69210R-022620 support both I²C and UART interfaces simultaneously?
No, the PD69210R-022620 supports I²C or UART-but not both simultaneously. Interface selection is determined by the voltage applied to pin 13 (I2C_ADDR_MEAS): a specific resistor divider sets either the I²C address or forces UART mode. Once configured, only one interface is active; the other remains disabled. Configuration is fixed at power-up and cannot be dynamically switched.
How does the PD69210R-022620 handle thermal management in high-power PoE applications?
The PD69210R-022620 uses a 5 mm × 5 mm QFN package with an exposed thermal pad (ePAD) that must be soldered to a VSSA-connected copper plane. Its junction-to-ambient thermal resistance is specified at 40.9°C/W under standard JEDEC conditions. Designers must follow Microchip's recommended PCB layout-including 5-mil stencil paste coverage of 65–80% of the ePAD-to maintain safe junction temperature below 100°C during sustained 45W-per-port operation.
Can the PD69210R-022620 be used in systems requiring legacy PoE device support?
Yes, the PD69210R-022620 includes legacy (reduced-capacitance) detection per port, enabling reliable identification and safe powering of pre-standard Powered Devices (PDs) compliant with early PoE implementations. This capability is implemented in firmware and requires no external components, preserving compatibility while maintaining full IEEE 802.3bt functionality for modern endpoints.
What is the significance of the "R" in the part number PD69210R-022620?
The "R" in PD69210R-022620 denotes the detection method: "R" indicates IEEE 802.3-only detection (excluding pre-standard PD support), whereas "C" would indicate combined IEEE 802.3 and pre-standard detection. However, per the official datasheet and ordering table, PD69210R-022620 retains full legacy detection capability - the "R" suffix reflects internal firmware configuration targeting optimized 802.3bt deployment with guaranteed compliance.
