Product details
Overview
PD69210R-035500-TR 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, integrated I²C/UART host interface, and pre-standard PD detection. It operates across –40°C to +85°C in a 32-pin 5 mm × 5 mm QFN package.
For engineers reviewing the PD69210R-035500-TR datasheet, PD69210R-035500-TR pinout, PD69210R-035500-TR application, or PD69210R-035500-TR equivalent, this page delivers verified technical context, real-world port control behavior, firmware-upgradeable architecture, thermal resistance (θJA = 40.9°C/W), and system-level integration guidance with PD69208T4/PD69204T4 managers.
Technical Context
The PD69210R-035500-TR implements a dual-mode communication architecture supporting both I²C (7-bit address, 400 kHz with clock stretch) and UART (19.2 kbps, 8N1) interfaces, enabling host-independent operation or coordinated control. Its firmware is factory-programmed and field-upgradeable via either interface.
It integrates a 32-pin QFN package with dedicated ESPI bus signals (MOSI/MISO/SCK/xCS) for synchronous communication with PoE managers, plus hardware control pins including xDISABLE_PORTS (active-low global port shutdown), xSys_OK (active-low system validity), and xINT_OUT (active-low event interrupt), all mapped to discrete physical terminals with defined drive strength and voltage thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IEEE Standards | Complies with 802.3af, 802.3at, 802.3bt, and HDBaseT (PoH) - enables full interoperability with Class 0–8 PDs and legacy pre-standard devices. |
| Logical Ports | Supports up to 48 logical ports built from 2-pair or 4-pair physical ports - allows flexible topology mapping in high-density switches. |
| Max Port Power | 45W per 2-pair port - meets IEEE 802.3bt Type 3/4 power delivery requirements for high-power endpoints like PTZ cameras and thin clients. |
| Supply Voltage | VDD = 3.0–3.63 V - compatible with standard 3.3V system rails; includes separate VDDA (analog) and VDD_CORE (1.2V) domains for noise isolation. |
| Operating Temp | –40°C to +85°C - qualified for industrial and enterprise networking environments without derating. |
| Thermal Resistance | θJA = 40.9°C/W - defines required PCB copper area and airflow for thermal management in continuous 48-port operation. |
| ESD Rating | HBM ±2000 V, CDM ±500 V - meets JESD22 Class 2/1 standards for robustness in manufacturing and field deployment. |
Pinout & Package
PD69210R-035500-TR is housed in a 32-pin, 5 mm × 5 mm plastic QFN package with exposed thermal pad (ePAD) requiring connection to VSSA for thermal performance. The package complies with RoHS, Pb-free, and MSL Level 1 reflow profiles (peak 260°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Reserved UART | Unused UART function; must be left open per datasheet. |
| 3 | xSys_OK/LED | Active-low system status output; drives low when firmware and manager communication are valid. |
| 4 | xDISABLE_PORTS | Active-low global port disable input; asserts immediate shutdown of all PoE ports on falling edge. |
| 5–8 | ESPI_MISO/SCK/xCS/MOSI | Dedicated SPI bus to PD69208T4/PD69204T4 managers at 1 MHz - enables real-time power monitoring and fault reporting. |
| 13 | I2C_ADDR_MEAS | Analog input selecting I²C address (0x04–0x3C) or UART mode via external resistor divider - eliminates need for address jumpers. |
| 15–16 | UART0_TX/RX | Full-duplex UART interface at 19.2 kbps - supports telemetry, configuration, and diagnostics without host CPU overhead. |
| 21–22 | I2C0_SDA/SCL | Bidirectional I²C interface with clock stretch support - enables multi-controller synchronization and shared bus operation. |
| 25 | xINT_OUT | Active-low interrupt output signaling port-on, port-fault, or voltage-out-of-range events - reduces polling overhead in host firmware. |
Key Features
| Feature | Design Value |
|---|---|
| Per-port power limiting | Configurable limit enforced in hardware; automatic port disconnect on violation - prevents overcurrent damage during PD insertion or fault conditions. |
| Legacy PD detection | Supports pre-standard PDs using reduced-capacitance detection - ensures backward compatibility with older VoIP phones and IP cameras. |
| Fast PoE boot | Ports power up within milliseconds of power-on, independent of host initialization - enables rapid system readiness in managed switches. |
| Perpetual PoE | Maintains powered state during host firmware upgrade or reset - eliminates service interruption for connected PDs like security cameras or access points. |
| LED stream interface | SPI-based direct LED control (xLED_OE/xLED_CS/xLED_LATCH2) - offloads LED management from host MCU and enables synchronized status indication. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PoE PSE controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PD69220R-035500-TR | LGA package (32-pin, 5 mm × 5 mm), θJA = 65.0°C/W, pin-compatible with PD69200 footprint - requires different PCB layout and thermal design. | Preferred for new designs targeting drop-in replacement of PD69200; not suitable for existing PD69210 layouts due to LGA vs QFN mechanical mismatch. | Select PD69220R-035500-TR only when redesigning PCB for LGA footprint or leveraging PD69200 legacy layout; otherwise retain PD69210R-035500-TR for QFN-based systems. |
| PD69200D-035500-TR | Generation 5 controller; supports only IEEE 802.3af/at (no 802.3bt or HDBaseT); lacks Fast PoE and Perpetual PoE features; higher θJA (52.1°C/W). | Restricted to legacy 30W-class deployments; cannot support Class 4 (90W) or PoH applications requiring enhanced negotiation and fault handling. | PD69200D-035500-TR is obsolete for new designs; PD69210R-035500-TR provides full 802.3bt compliance, lower thermal resistance, and field-upgradeable firmware - essential for future-proof PoE infrastructure. |
Compared with PD69220R-035500-TR, PD69210R-035500-TR offers superior thermal performance (θJA 40.9 vs 65.0°C/W) in QFN packaging, while PD69200D-035500-TR lacks 802.3bt support and modern reliability features - making PD69210R-035500-TR the optimal choice for new 48-port, high-power PoE switch designs.

FAQ
What IEEE PoE standards does the PD69210R-035500-TR support?
The PD69210R-035500-TR supports IEEE 802.3af (PoE), 802.3at (PoE+), 802.3bt (PoE++ Types 3 and 4), and HDBaseT Power over HDBaseT (PoH). It also implements legacy pre-standard PD detection. This full standard coverage enables interoperability with Class 0–8 powered devices and ensures compliance in new infrastructure deployments requiring up to 90W per port.
Does the PD69210R-035500-TR require an external microcontroller to operate?
No, the PD69210R-035500-TR includes factory-programmed firmware and can operate standalone with default profiles. It supports autonomous port management, power limiting, and fault response without host intervention. A host MCU is optional and used only for advanced configuration, telemetry, or custom power policies via I²C or UART - reducing system BOM and firmware development effort.
What is the difference between PD69210R-035500-TR and PD69220R-035500-TR?
The PD69210R-035500-TR uses a 32-pin QFN package (θJA = 40.9°C/W), while PD69220R-035500-TR uses a 32-pin LGA package (θJA = 65.0°C/W) and is pin-compatible with the legacy PD69200 footprint. Both share identical firmware and feature sets, but their mechanical and thermal characteristics differ - requiring distinct PCB layouts and thermal design approaches.
How is communication configured between the PD69210R-035500-TR and host processor?
Communication is configurable via I²C (7-bit address, 400 kHz with clock stretch) or UART (19.2 kbps, 8N1). Pin #13 (I2C_ADDR_MEAS) selects the interface and I²C address using an external resistor divider. No hardware changes are needed to switch modes - only firmware configuration and resistor selection, enabling flexible integration across host platforms.
Can the PD69210R-035500-TR support perpetual PoE during host firmware updates?
Yes, the PD69210R-035500-TR supports Perpetual PoE - maintaining continuous power delivery to connected PDs even when the host MCU is in reset, undergoing firmware upgrade, or temporarily unresponsive. This ensures zero downtime for critical endpoints like security cameras, access control readers, and emergency lighting systems.
