Product details
Overview
PD69200R-017203 from Microchip Technology is a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller IC designed to manage IEEE 802.3af/at/bt and HDBaseT PoH compliant power delivery across up to 48 logical ports via cascaded PoE managers. It features 32-pin QFN packaging, supports 45 W two-pair and 90 W four-pair per port, and integrates UART/I2C/SPI host interfaces for system-level control in enterprise switches and midspan injectors.
For engineers reviewing the PD69200R-017203 datasheet, PD69200R-017203 pinout, PD69200R-017203 application, or PD69200R-017203 equivalent, key selection criteria include IEEE 802.3bt compliance, 32-pin QFN thermal performance (θJA = 33 °C/W), firmware-upgradable architecture, and compatibility with PD69208T4/PD69204T4/PD69208M PoE managers.
Technical Context
The PD69200R-017203 implements a hierarchical PSE architecture where it acts as the central controller coordinating up to 12 PoE manager ICs (e.g., PD69208T4) via 1 MHz SPI bus, enabling scalable 48-port systems. Its firmware-pre-programmed and field-upgradeable via UART or I2C-supports three power management modes (Class, Dynamic, Static) and legacy detection.
Hardware-level integration includes dedicated interrupt outputs (xINT_OUT, xSys_OK/LED), LED stream control (xLED_CS/xLED_LATCH/xLED_OE), and dual communication path selection (I2C_ADDR_MEAS pin configures interface mode and 7-bit I2C address). The device uses an NXP MKL15Z128VFM4 core but is functionally abstracted for PoE-specific control-not general-purpose MCU use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IEEE Standards | Complies with 802.3af, 802.3at, 802.3bt, and HDBaseT PoH-enables interoperable high-power PoE delivery up to 90 W per port. |
| Port Capacity | Supports cascade of up to 12 PoE managers for 48 logical ports-scales infrastructure without redesigning controller layer. |
| Power per Port | 45 W on two pairs; 90 W on four pairs (802.3bt Type 4)-meets high-power requirements for PTZ cameras, thin clients, and wireless APs. |
| Package | 32-pin QFN, 5 mm × 5 mm, MSL3, RoHS-compliant-enables compact, thermally efficient layout with ePAD grounding. |
| Supply Voltage | VDD = 3.0–3.63 V (typical 3.3 V)-compatible with standard logic rails and low-noise LDO regulation. |
| Communication | UART (19.2 kbps, 8N1), I2C (400 kHz, clock-stretch required), SPI (1 MHz master-to-manager)-provides flexible host interface options. |
| Thermal Resistance | θJA = 33 °C/W, θJC = 1.8 °C/W-supports sustained operation at 85 °C ambient with proper PCB copper mass under ePAD. |
Pinout & Package
PD69200R-017203 is housed in a 32-pin, 5 mm × 5 mm QFN package with exposed thermal pad (ePAD) requiring connection to VSSA ground plane for thermal integrity. The package meets MSL3 moisture sensitivity and RoHS 6/6 Pb-free standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–2, 9, 14, 17–18, 23, 29 | Reserved / Analog_IN / Oscillator | Factory-reserved pins; analog inputs require defined bias (3.3 V or GND); oscillator pins must remain open. |
| 3–6 (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO) | SPI Interface to PoE Managers | Controls up to 12 PD6920x managers at 1 MHz; chip select active-low, clock output, bidirectional data lines. |
| 7, 15 (VDDA, VDD), 8, 16 (VSSA, VSSD), ePAD | Power & Ground | Dual 3.3 V supplies (analog/digital), separate analog/digital grounds, and thermally critical ePAD tied to VSSA. |
| 11–12 (UART0_RX, UART0_TX), 20–21 (I2C0_SCL, I2C0_SDA), 22 (I2C_ADDR_MEAS) | Host Communication Interface | Configurable UART or I2C (7-bit address set by analog voltage on pin 22); UART requires pull-up, I2C requires clock stretch support. |
| 19 (xRESET), 24 (xI2C_MESSAGE_READY), 25 (xINT_OUT), 31 (xDISABLE_PORTS), 32 (xSys_OK/LED) | System Control & Status | Active-low reset with self-reset capability; interrupt signaling for events; global port disable; system validity indicator. |
| 26–28 (xLED_CS, xLED_LATCH, xLED_OE), 30 (FAN_CONTROL) | Peripheral Management | Drives LED streams for port status indication; fan control output is active-high logic signal for external driver. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PoE PSE controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PD69220 | Pin-compatible with identical feature set and 802.3bt/PoH support; newer SAM D21-based architecture. | Recommended for new designs due to updated core and ongoing firmware roadmap; PD69200 is for legacy design continuity. | Select PD69220 for new projects requiring long-term roadmap alignment; PD69200 remains valid for drop-in replacement in existing layouts. |
| PD69210 | Also SAM D21-based and pin-compatible, but targets lower-cost, lower-port-count applications (e.g., 8–24 port). | Optimized for cost-sensitive mid-tier switches; lacks some advanced features like 48-port cascade depth of PD69200/PD69220. | Choose PD69210 when scaling to ≤24 ports and budget constraints outweigh need for maximum cascade flexibility. |
Compared with PD69200R-017203, PD69220 offers identical functionality with modernized silicon and extended roadmap support, while PD69210 trades cascade depth and some power bank features for cost reduction-making PD69200R-017203 optimal for maintaining high-port-count legacy systems without redesign.

FAQ
What IEEE PoE standards does PD69200R-017203 support?
PD69200R-017203 supports IEEE 802.3af (Type 1), 802.3at (Type 2), 802.3bt (Types 3 and 4), and HDBaseT PoH standards. It delivers up to 45 W on two pairs and 90 W on four pairs per port, with full legacy detection and classification compliance verified per standard test procedures in the official Microchip datasheet DS00003460B.
Is PD69200R-017203 pin-compatible with other Microchip PSE controllers?
Yes, PD69200R-017203 is pin-compatible with PD69220, sharing identical 32-pin QFN footprint, pin functions, and electrical characteristics. This enables direct replacement in existing PCB layouts. PD69210 shares the same package but differs in internal architecture and some peripheral mappings-requiring validation before substitution.
How is firmware updated on PD69200R-017203?
Firmware on PD69200R-017203 is updated in-field via UART or I2C interface using Microchip's 15-byte protocol. The device ships with pre-programmed firmware identifiable by ordering part number suffixes (e.g., VVVV/SS codes), and updates can be performed without removing the IC from the board-supporting post-deployment standard enhancements and bug fixes.
What is the role of the I2C_ADDR_MEAS pin on PD69200R-017203?
Pin 22 (I2C_ADDR_MEAS) on PD69200R-017203 serves dual purpose: selecting between UART and I2C host interface modes, and setting the 7-bit I2C slave address (0x04 to 0x3C in hexadecimal) via analog voltage level. An external resistor network determines the voltage threshold, as specified in Table 1-2 of DS00003460B.
Does PD69200R-017203 require an external microcontroller to operate?
No, PD69200R-017203 can operate autonomously ("stand alone") using its onboard firmware for basic PoE control, classification, and power management. A host microcontroller is optional and used only when advanced system integration-such as GUI interaction, custom power policies, or telemetry reporting-is required via UART, I2C, or SPI.
