Product details
Overview
PD69200C-016701 from Microchip Technology is a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller IC designed for IEEE 802.3af/at/bt and HDBaseT PoH-compliant systems. It integrates with PD69208T4/PD69204T4/PD69208M managers to deliver up to 90 W per four-pair port, supports Class/Dynamic/Static power management modes, and operates in a 32-pin 5 mm × 5 mm QFN package rated for –40 °C to +85 °C ambient.
For engineers reviewing the PD69200C-016701 datasheet, PD69200C-016701 pinout, PD69200C-016701 application, or PD69200C-016701 equivalent, key selection criteria include IEEE 802.3bt compliance, 45 W two-pair / 90 W four-pair power capability, SPI/I2C/UART host interface support, 16-bank power supply architecture, and legacy detection compatibility.
Technical Context
The PD69200C-016701 implements a firmware-driven PSE control architecture based on the NXP MKL15Z128VFM4 microcontroller core. It communicates with PoE managers via 1 MHz SPI (ESPI bus) and supports host interaction through UART (19.2 kbps) or I2C (400 kHz with clock stretch), with interface selection determined by analog voltage on pin #22 (I2C_ADDR_MEAS).
Its hardware design enables cascading up to 12 PoE controllers for 48 logical ports, manages port priority and matrix configuration, and provides real-time port status, measurements, and system-level event interrupts (xINT_OUT) alongside system validity indication (xSys_OK/LED System OK) and disable control (xDISABLE_PORTS).
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 legacy and high-power PDs. |
| Max Port Power | 45 W per two-pair port; 90 W per four-pair port - meets Type 3 and Type 4 PSE requirements under 802.3bt. |
| Power Management | Supports Class (LLDP), Dynamic, and Static modes - allows flexible power allocation based on PD classification or real-time load sensing. |
| Port Scalability | Cascades up to 12 controllers for 48 logical ports - supports large-scale enterprise switches and midspans without external arbitration logic. |

| Package | 32-pin QFN, 5 mm × 5 mm, MSL3 - surface-mountable with exposed thermal pad for enhanced thermal dissipation (θJC = 1.8 °C/W). |
Pinout & Package
PD69200C-016701 is housed in a 32-pin, 5 mm × 5 mm QFN package with an exposed thermal pad (ePAD) requiring connection to VSSA. The package complies with RoHS and Pb-free standards and supports reflow profiles up to 260 °C peak temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–2, 9, 14, 17–18, 23, 29 | Reserved / Analog_IN / Oscillator | Factory-reserved pins; some require pull-up/pull-down or connection to 3.3 V/GND per AN3361 - not user-configurable for functional I/O. |
| 3–6 (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO) | SPI Interface to PoE Manager | Controls PD69208T4/PD69204T4/PD69208M managers at 1 MHz - enables port power sequencing, measurement readback, and fault reporting. |

| 20–21, 24 (I2C0_SCL, I2C0_SDA, xI2C_MESSAGE_READY) | I2C Host Interface | 400 kHz bidirectional I2C with clock stretch support; xI2C_MESSAGE_READY signals data readiness - simplifies integration with resource-constrained microcontrollers. |
| 25 (xINT_OUT) | System/Port Event Interrupt | Active-low open-drain output asserting on preconfigured events (e.g., port fault, overtemp, power limit breach) - enables responsive host intervention. |
| 26–28 (xLED_CS, xLED_LATCH, xLED_OE) | LED Stream Control | Drives multiplexed LED indicators per port using serial shift register protocol - eliminates need for external LED drivers or GPIO expansion. |
| 31 (xDISABLE_PORTS) | Global Port Shutdown | Active-low input disabling all PoE ports simultaneously - supports emergency power-off or maintenance mode without firmware involvement. |
| 32 (xSys_OK/LED System OK) | System Validity Indicator | Active-low output reflecting firmware health and initialization status - configurable via software mask to indicate system readiness or fault condition. |

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; based on Microchip SAM D21 instead of NXP MKL15Z128VFM4; newer firmware platform. | Recommended for new designs due to active development and extended lifecycle support; same 90 W four-pair capability and 32-pin QFN footprint. | Select PD69220 when starting new designs to ensure long-term availability and access to latest firmware features. |
| PD69210 | Based on Microchip SAM D21; supports same IEEE standards and power levels but lacks cascade support beyond 8 logical ports per controller. | Targeted at cost-sensitive, lower-port-count applications (e.g., 8- or 16-port PoE injectors); no 48-port scalability via daisy-chain. | Choose PD69210 only for compact, fixed-port-count systems where full 48-port cascade is unnecessary. |
Compared with PD69200C-016701, PD69220 offers identical functionality with updated silicon and firmware roadmap, while PD69210 trades scalability for reduced complexity and cost - making PD69200C-016701 the optimal choice for maintaining legacy 48-port designs requiring field-upgradable firmware and proven thermal performance.

FAQ
What IEEE PoE standards does PD69200C-016701 support?
PD69200C-016701 supports IEEE 802.3af (Type 1), 802.3at (Type 2), 802.3bt (Type 3 and Type 4), and HDBaseT PoH standards. It delivers up to 45 W on two-pair and 90 W on four-pair configurations, with full backward compatibility for legacy PDs. All compliance is implemented in firmware and verified per IEEE test procedures in the official Microchip datasheet DS00003460B.
How does PD69200C-016701 interface with PoE managers like PD69208T4?
PD69200C-016701 interfaces with PD69208T4, PD69204T4, or PD69208M managers via a dedicated 1 MHz SPI bus (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO). This link handles port power control, fault reporting, and real-time measurements. Each manager is assigned a unique address (0–11), enabling up to 12 controllers per system - a capability confirmed in Section 1.5 and Figure 1-1 of the PD69200C-016701 datasheet.
Can PD69200C-016701 operate without a host microcontroller?
Yes, PD69200C-016701 can operate in standalone mode using pre-programmed firmware profiles. It supports autonomous port detection, classification, power application, and fault recovery without host intervention. Host communication via UART or I2C is optional and used only for configuration changes, diagnostics, or telemetry - as stated in Section 1.1 "Firmware" of the DS00003460B datasheet.
What is the function of pin #22 (I2C_ADDR_MEAS) on PD69200C-016701?
Pin #22 (I2C_ADDR_MEAS) on PD69200C-016701 serves a dual purpose: it selects between UART and I2C host interfaces, and sets the 7-bit I2C slave address. An external resistor network applies specific voltage levels (0–3.3 V) to this pin, determining both interface mode and address value (e.g., 0x04 to 0x3C). This analog configuration method is detailed in Table 1-2 and Figure 1-3 of the PD69200C-016701 datasheet.
Does PD69200C-016701 support firmware updates in the field?
Yes, PD69200C-016701 supports field-upgradeable firmware via its I2C or UART interface. Firmware updates use the same 15-byte protocol used for configuration and telemetry, and are performed without requiring JTAG or SWD debug access. The update process is documented in Microchip Application Note AN3361 and the PD69200 Communication Protocol User Guide referenced in DS00003460B.
