Product details
Overview
PD69200R-016103 from Microchip Technology is a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller IC based on the NXP MKL15Z128VFM4 microcontroller core. It implements IEEE 802.3af/at/bt and HDBaseT PoH standards, supports up to 48 logical ports via cascading, delivers up to 90 W per four-pair port, and operates in Class, Dynamic, or Static power management modes. It serves as the central intelligence layer in multi-port PoE switches for enterprise networking infrastructure.
For engineers reviewing the PD69200R-016103 datasheet, PD69200R-016103 pinout, PD69200R-016103 application, or PD69200R-016103 equivalent, key selection criteria include IEEE 802.3bt compliance, 32-pin QFN thermal performance, SPI/I2C/UART host interface flexibility, firmware-upgradability, and compatibility with PD69208T4/PD69204T4/PD69208M PoE managers.
Technical Context
The PD69200R-016103 functions as the system-level PSE controller in a hierarchical PoE architecture, communicating via 1 MHz SPI with up to 12 PoE manager ICs (e.g., PD69208T4) to coordinate port detection, classification, power delivery, and fault monitoring across up to 48 ports. Its firmware-pre-programmed and field-upgradeable via I2C or UART-supports three distinct power allocation modes and integrates legacy detection for backward compatibility.
Hardware interfaces include dedicated ESPI bus pins (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO) for manager communication, dual host interfaces (I2C0_SCL/I2C0_SDA with clock stretch support and UART0_RX/UART0_TX at 19.2 kbps), and configurable control signals (xINT_OUT, xDISABLE_PORTS, xSys_OK/LED) for real-time system event handling and safety shutdown.
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 all standard-compliant Powered Devices. |
| Max Port Power | 90 W per four-pair port (802.3bt Type 4) - supports high-power applications like PTZ cameras, thin clients, and wireless APs. |
| Port Scalability | Cascades up to 12 PoE managers for 48 logical ports - eliminates need for external arbitration logic in large-scale deployments. |
| Power Management | Three modes: Class (LLDP), Dynamic, Static - allows precise per-port power budgeting aligned with device capability or policy. |
| Digital Supply | VDD = 3.0–3.63 V @ 25°C - compatible with standard 3.3 V system rails; requires decoupling per analog/digital supply domains (VDDA/VDD). |

| ESD Rating | HBM ±2000 V, CDM ±500 V - meets industrial-grade robustness requirements for board-level handling and field deployment. |
Pinout & Package
PD69200R-016103 is housed in a 32-pin, 5 mm × 5 mm QFN package with an exposed thermal pad (ePAD) that must be connected to VSSA for thermal integrity. The package is RoHS-compliant, MSL3 rated, and qualified for –40°C to +85°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–2, 9, 13–14, 17–18, 23, 29 | Reserved / Analog_IN / Oscillator | Factory-reserved or internal-use pins; some require tie-high/tie-low per datasheet (e.g., Pin 9 to 3.3 V, Pin 14 to GND/3.3 V via 10 kΩ). |
| 3–6 (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO) | ESPI Bus Interface | Primary control path to PoE managers; 1 MHz SPI clock, active-low chip select, full-duplex data flow for configuration and telemetry. |
| 7, 15 (VDDA, VDD) | Analog & Digital Supply | Separate 3.3 V supplies for analog and digital domains - mandatory independent decoupling to ensure ADC accuracy and logic stability. |
| 8, 16 (VSSA, VSSD) | Analog & Digital Ground | Independent ground planes required; ePAD must connect to VSSA to maintain thermal and noise isolation. |
| 11–12, 20–21 (UART0_RX, UART0_TX, I2C0_SCL, I2C0_SDA) | Host Communication | Dual-interface host link: UART (19.2 kbps, pull-up required) or I2C (400 kHz, clock-stretch supported); mode selected by analog voltage on Pin 22. |
| 19 (xRESET), 24 (xI2C_MESSAGE_READY), 25 (xINT_OUT), 31 (xDISABLE_PORTS), 32 (xSys_OK/LED) | System Control & Status | Active-low control/status signals: hardware reset, interrupt notification, global port disable, and system validity indication - enable deterministic system-level coordination. |
| 26–28 (xLED_CS, xLED_LATCH, xLED_OE) | LED Stream Interface | Three-wire interface for driving status LED banks - supports multiplexed visual feedback without MCU intervention. |
| 30 (FAN_CONTROL) | Fan Driver Output | Active-high logic output for thermal management - directly drives fan controllers or discrete MOSFETs in PoE switch enclosures. |
Key Features
| Feature | Design Value |
|---|---|
| Firmware Upgradability | Field firmware updates via I2C or UART using 15-byte protocol - enables post-deployment feature enhancements and bug fixes without hardware change. |
| I2C/UART Interface Selection | Pin 22 (I2C_ADDR_MEAS) sets both communication mode and I2C address (0x4 to 0x3C) via resistor ladder - simplifies multi-controller addressing in dense systems. |
| Four-Pair Power Delivery | Supports IEEE 802.3bt Type 4 (90 W) on four-pair ports - eliminates need for dual-cable or external DC injectors in high-power endpoint deployments. |
| 16-Power Bank Architecture | Manages up to 16 independent power banks derived from four input supplies - enables granular power budgeting and redundancy across multiple PoE subsystems. |
| Legacy Detection | Identifies non-standard PDs using resistive signature detection - ensures backward compatibility with pre-802.3af devices in mixed-installation environments. |
| Interrupt-Driven Event Handling | xINT_OUT asserts low on pre-configured events (e.g., port fault, overtemperature, classification failure) - reduces host polling overhead and accelerates fault response. |

FAQ
What IEEE PoE standards does the PD69200R-016103 support?
The PD69200R-016103 supports IEEE 802.3af (15.4 W), 802.3at (30 W), 802.3bt (up to 90 W Type 4), and HDBaseT Power over HDBaseT (PoH) standards. It performs full four-pair detection, classification, and power delivery per clause 145 of IEEE 802.3-2018, including legacy detection for non-standard devices. All compliance is implemented in firmware and verified per standard test procedures.
How does the PD69200R-016103 interface with PoE manager ICs like PD69208T4?
The PD69200R-016103 communicates with PoE manager ICs such as PD69208T4 via a dedicated ESPI bus using pins ESPI_xCS, ESPI_SCK, ESPI_MOSI, and ESPI_MISO. It operates at 1 MHz SPI clock frequency, supports up to 12 managers in a daisy-chain or star topology, and exchanges configuration, telemetry, and fault data using a defined packet structure. This interface offloads low-level power switching control from the host processor.
Can the PD69200R-016103 firmware be updated in the field?
Yes, the PD69200R-016103 firmware is field-upgradeable via its I2C or UART interface using the documented 15-byte communication protocol. Updates are performed without requiring JTAG/SWD access, enabling remote feature enhancements, bug fixes, and parameter tuning in deployed systems. Firmware version is encoded in the part number suffix (e.g., "R-016103" indicates revision and configuration).
What is the function of Pin 22 (I2C_ADDR_MEAS) on the PD69200R-016103?
Pin 22 (I2C_ADDR_MEAS) on the PD69200R-016103 serves a dual purpose: it selects between UART and I2C host communication modes, and sets the 7-bit I2C slave address (0x4 to 0x3C) via an external resistor ladder. Voltage thresholds from 0 V to 3.3 V determine both mode and address, allowing flexible multi-controller addressing without additional GPIOs or configuration registers.
Does the PD69200R-016103 support thermal management features?
Yes, the PD69200R-016103 supports thermal management through its FAN_CONTROL pin (Pin 30), which provides an active-high logic output to drive external fan controllers or discrete MOSFETs. Combined with its low thermal resistance (θJC = 1.8°C/W) and ePAD-connected thermal pad, the PD69200R-016103 enables reliable operation in thermally constrained PoE switch chassis up to 85°C ambient.
