Product details
Overview
PD69210C-022619 from Microchip Technology is a Generation 6 IEEE 802.3af/at/bt and HDBaseT-compliant PoE Power Sourcing Equipment (PSE) controller for Ethernet switches. It supports up to 48 logical ports (2-pair or 4-pair), delivers up to 45W per port, operates across –40°C to +85°C, and integrates UART/I²C host interface with pre-programmed firmware for standalone or host-coordinated operation in industrial PoE infrastructure.
For engineers reviewing the PD69210C-022619 datasheet, PD69210C-022619 pinout, PD69210C-022619 application, or PD69210C-022619 equivalent, key selection criteria include IEEE 802.3bt compliance, 48-port scalability, per-port power limiting, fast/perpetual PoE capability, and compatibility with PD69208T4/PD69204T4/PD69208M PoE managers in QFN-based switch designs.
Technical Context
The PD69210C-022619 implements a dual-mode PSE control architecture: it manages port detection, classification, power-up, monitoring, and fault recovery via integrated firmware derived from the SAM D21 family. Its hardware supports both I²C (7-bit address, clock stretch required) and UART (19.2 kbps, 8N1) host interfaces with configurable selection via analog voltage on I2C_ADDR_MEAS (Pin 13).
It communicates with up to 12 PoE managers (e.g., PD69208T4) over an ESPI bus at 1 MHz, using a fixed 15-byte protocol for telemetry and command exchange. System-level functions include legacy PD detection, dynamic/static/class-based power management, interrupt-driven event reporting (port on/off/fault), and system-level status signaling via xSys_OK (active-low) and xDISABLE_PORTS (active-low).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IEEE Standards | Complies with 802.3af, 802.3at, 802.3bt, and HDBaseT (PoH) - enables full backward/forward compatibility and multi-standard deployment. |
| Logical Ports | Supports up to 48 logical ports - allows scalable integration into enterprise or carrier-grade 48-port Ethernet switches. |
| Max Per-Port Power | 45W (4-pair) - meets IEEE 802.3bt Type 3/4 requirements for high-power devices like PTZ cameras and thin clients. |
| Operating Temp | –40°C to +85°C - qualified for industrial and outdoor networking equipment environments. |
| Supply Voltage | VDD/VDDA = 3.0–3.63 V - compatible with standard 3.3V system rails; requires separate 1.2V core supply (VDD_CORE). |
| Communication | UART (19.2 kbps, 8N1) or I²C (up to 400 kHz, clock stretch required) - provides flexible host integration without protocol translation overhead. |
| Firmware | Pre-programmed, field-upgradeable via UART/I²C - eliminates boot-time dependency on host CPU and supports remote firmware updates. |
Pinout & Package
PD69210C-022619 is housed in a 32-pin, 5 mm × 5 mm QFN package with exposed thermal pad (ePAD), rated MSL 1, RoHS-compliant, and designed for reflow peak temperature of 260 °C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Reserved (UART) | Reserved UART function; must be left open - no connection required for standard operation. |
| 3 | xSys_OK/LED | Active-low system validity indicator - signals host or drives LED when PSE subsystem is fully initialized and stable. |
| 4 | xDISABLE_PORTS | Active-low global port shutdown - asserts low to immediately disable all PoE ports during fault or maintenance. |
| 5–8 | ESPI_MISO/SCK/xCS/MOSI | ESPI bus interface to PoE managers - enables synchronous 1 MHz SPI communication with up to 12 PD6920x devices. |
| 13 | I2C_ADDR_MEAS | Analog input for UART/I²C mode selection and I²C address setting - resistor divider configures interface and 7-bit address (0x04–0x3C). |
| 15–16 | UART0_TX/RX | Full-duplex UART interface - transmits telemetry and receives 15-byte host commands at 19.2 kbps (8N1). |
| 21–22 | I2C0_SDA/SCL | Bidirectional I²C interface - supports clock-stretching host; used for configuration, status polling, and firmware updates. |
| 25 | xINT_OUT | Active-low interrupt output - signals host on events including port power-on, fault, classification failure, or voltage out-of-range. |
| ePAD | Thermal Ground | Exposed pad connected to VSSA - mandatory for thermal performance; requires sufficient copper area and solder coverage. |
Key Features
| Feature | Design Value |
|---|---|
| Fast PoE | Enables immediate port power-up after cold start without waiting for host initialization - reduces system boot time in unmanaged switches. |
| Perpetual PoE | Maintains powered state to connected PDs during host firmware upgrade or reset - ensures zero-power-interruption for critical endpoints. |
| Legacy Detection | Supports pre-standard PDs via reduced-capacitance detection per port - preserves compatibility with older VoIP phones and IP cameras. |
| LED Stream Interface | Dedicated SPI-based LED control (xLED_OE/xLED_CS/xLED_LATCH2) - drives external LED arrays for real-time port status visualization. |
| Power Management Modes | Three configurable modes (Class/LLDP, Dynamic, Static) - allows precise power budgeting aligned with network policy or device capability. |

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; MSL 3 vs. MSL 1. | Requires PCB redesign or footprint adaptation; suitable for new layouts targeting higher thermal resistance tolerance. | Select PD69220 only when leveraging its LGA package advantages (e.g., improved manufacturability on dense boards) and accepting MSL 3 handling requirements. |
| PD69200 | Legacy Generation 5 controller; lacks IEEE 802.3bt and HDBaseT support; lower port count scalability; no Fast/Perpetual PoE. | Restricted to 802.3af/at-only systems; not suitable for new designs requiring >30W/port or future-proofing. | PD69200 is obsolete for new designs; PD69210C-022619 offers full standard compliance, enhanced reliability features, and long-term roadmap alignment. |
Compared with PD69220 and PD69200, PD69210C-022619 delivers identical IEEE 802.3bt/HDBaseT functionality in a more robust MSL 1 QFN package, enabling drop-in replacement in existing PD69210 footprints while supporting faster time-to-market and simplified thermal design versus LGA alternatives.

FAQ
What IEEE PoE standards does the PD69210C-022619 support?
The PD69210C-022619 supports IEEE 802.3af (PoE), 802.3at (PoE+), 802.3bt (PoE++ Types 3 and 4), and HDBaseT (Power over HDBaseT). It enables full backward compatibility with legacy PDs and forward readiness for high-power endpoints up to 45W per port. All standard compliance is implemented in firmware and verified per Microchip DS00003424D.
Does the PD69210C-022619 require an external microcontroller to operate?
No - the PD69210C-022619 includes pre-programmed, field-upgradeable firmware derived from the SAM D21 family and can operate in standalone mode. Host interaction via UART or I²C is optional for configuration, telemetry, or advanced power management; basic PoE functionality (detection, classification, power-up) runs autonomously.
What is the package type and thermal rating of the PD69210C-022619?
The PD69210C-022619 uses a 32-pin, 5 mm × 5 mm plastic QFN package with exposed thermal pad (ePAD), rated Moisture Sensitivity Level (MSL) 1 and RoHS-compliant. Its junction-to-ambient thermal resistance (θJA) is 40.9 °C/W, and it supports peak reflow temperatures up to 260 °C per JEDEC J-STD-020.
How many PoE managers can the PD69210C-022619 control simultaneously?
The PD69210C-022619 communicates with up to 12 PoE managers (e.g., PD69208T4, PD69204T4, or PD69208M) over its dedicated ESPI bus at 1 MHz. Each manager is assigned a unique address (0–11) via ADDR0–ADDR3 pins, enabling coordinated control of up to 48 logical PoE ports in a single system.
What are the key differences between PD69210C-022619 and PD69220?
PD69210C-022619 and PD69220 share identical features, firmware, and electrical specifications but differ in physical package (QFN vs. LGA) and pinout. PD69210C-022619 uses a 32-pin QFN with MSL 1, while PD69220 uses a 32-pin LGA with MSL 3 and higher θJA (65.0 °C/W). They are not pin-compatible; PCB layout must match the specific package.
