Product details

Overview

PD69200R-035500 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 NXP MKL15Z128VFM4-based firmware, supports up to 48 logical ports via cascading, delivers up to 90 W per four-pair port, and operates in a 32-pin 5 mm × 5 mm QFN package. It serves as the central intelligence layer in multi-port PoE switches and midspans.

For engineers reviewing the PD69200R-035500 datasheet, PD69200R-035500 pinout, PD69200R-035500 application, or PD69200R-035500 equivalent, key selection criteria include IEEE 802.3bt compliance, SPI/I2C/UART host interface flexibility, 16-power-bank architecture, legacy detection support, and compatibility with PD69208T4/PD69204T4/PD69208M managers.

Technical Context

The PD69200R-035500 implements a hierarchical PSE control architecture: it communicates with PoE manager ICs (e.g., PD69208T4) via 1 MHz SPI slave interface and interfaces with host microprocessors via UART (19.2 kbps) or I2C (400 kHz with clock stretch). Its firmware-pre-programmed and field-upgradeable-supports three power management modes (Class, Dynamic, Static) and enables port-level measurements, priority-based port matrixing, and fast/perpetual PoE operation.

Hardware integration includes dedicated pins for LED stream control (xLED_CS/xLED_LATCH/xLED_OE), system status indication (xSys_OK), interrupt signaling (xINT_OUT), and thermal-aware operation via ePAD-connected ground. The device relies on external 3.3 V digital/analog supplies (VDD/VDDA) and supports RoHS-compliant Pb-free reflow up to 260 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
IEEE Standards	Complies with 802.3af, 802.3at, 802.3bt, and HDBaseT PoH-enables interoperability with Class 0–8 powered devices and four-pair high-power delivery.
Max Port Power	90 W per port (four-pair mode per IEEE 802.3bt Type 4)-supports high-power endpoints like PTZ cameras, thin clients, and wireless APs.
Port Scalability	Cascades up to 12 PoE controllers for 48 logical ports-enables modular, scalable PSE system design without host CPU overhead.
Power Management	Supports Class (LLDP), Dynamic, and Static modes-allows precise per-port power allocation based on negotiation, real-time load, or fixed budgeting.

Package	32-pin QFN, 5 mm × 5 mm, 0.5 mm pitch, exposed thermal pad (ePAD)-ensures compact board layout and efficient thermal dissipation (θJA = 33 °C/W).
Operating Temp	–40 °C to +85 °C ambient-validated for industrial-grade deployment in uncontrolled environments including telecom cabinets and outdoor enclosures.

Pinout & Package

PD69200R-035500 is housed in a 32-pin, 5 mm × 5 mm QFN package with an exposed thermal pad (ePAD) requiring connection to VSSA for optimal thermal performance. The package complies with MSL3 and RoHS standards, and supports Pb-free reflow profiles peaking at 260 °C.

Pin/Terminal	Circuit Role	Design Meaning
1–2, 9, 14, 17–18, 23, 29	Reserved / Analog_IN / Oscillator	Factory-reserved or analog input pins; most require tie-high/tie-low per datasheet (e.g., Pin 9 to 3.3 V, Pin 14 to GND via 10 kΩ).
3–6 (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO)	SPI Interface to PoE Manager	Controls PD69208T4/PD69204T4/PD69208M managers at 1 MHz; ESPI_xCS active-low chip select enables multi-IC daisy-chaining.

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 firmware capabilities; newer silicon revision with enhanced manufacturing yield and extended lifecycle support.	Targeted for new designs only; not qualified for legacy qualification programs requiring PD69200-specific firmware versioning or documentation traceability.	Select PD69220 for greenfield projects where long-term supply continuity and latest firmware features are prioritized.
PD69210	Based on Microchip SAM D21 (ARM Cortex-M0+), not NXP Kinetis; differs in debug interface (SWD vs JTAG), memory map, and peripheral register layout.	Requires firmware porting effort; lacks direct firmware binary compatibility with PD69200; optimized for lower-cost, lower-power PSE implementations.	Choose PD69210 when migrating to ARM ecosystem, reducing BOM cost, or leveraging Microchip's unified SAM toolchain and support infrastructure.

Compared with PD69200R-035500, PD69220 offers identical functionality with improved supply chain longevity, while PD69210 introduces architectural divergence requiring firmware adaptation but enables cost-sensitive, ARM-native development-making PD69200R-035500 the optimal choice for maintaining existing NXP-based designs with certified firmware revisions.

FAQ

What IEEE PoE standards does the PD69200R-035500 support?

The PD69200R-035500 supports IEEE 802.3af (Type 1), 802.3at (Type 2), 802.3bt (Types 3 and 4), and HDBaseT Power over HDBaseT (PoH) standards. It enables full 90 W four-pair power delivery per port under 802.3bt and includes legacy detection for pre-standard powered devices. All compliance is implemented in firmware and verified per Microchip's DS00003460B datasheet.

Is the PD69200R-035500 pin-compatible with other members of the PD692xx family?

Yes, the PD69200R-035500 is pin-compatible with the PD69220, sharing identical pinout, package dimensions, and electrical interface definitions. However, it is not pin-compatible with the PD69210, which uses a different underlying MCU architecture (SAM D21 vs NXP MKL15Z128VFM4) and exhibits divergent debug and peripheral pin assignments.

How does the PD69200R-035500 interface with PoE manager ICs like PD69208T4?

The PD69200R-035500 communicates with PoE manager ICs-including PD69208T4, PD69204T4, and PD69208M-via a dedicated 1 MHz SPI slave interface using pins ESPI_xCS, ESPI_SCK, ESPI_MOSI, and ESPI_MISO. Each manager is assigned a unique address (0–11), allowing up to 12 managers per controller, enabling scalable 48-port system architectures.

Can firmware on the PD69200R-035500 be updated in the field?

Yes, the PD69200R-035500 supports field-upgradable firmware via its UART or I2C host interface using Microchip's 15-byte protocol. Firmware updates can be performed without removing the device from the PCB, enabling post-deployment bug fixes, feature additions, and security patches-consistent with the firmware architecture described in DS00003460B Section 1.1.

What thermal considerations apply to the PD69200R-035500 in high-power PoE systems?

The PD69200R-035500 features a thermally enhanced 32-pin QFN package with an exposed ePAD that must be soldered to a large copper pour connected to VSSA. Its junction-to-ambient thermal resistance (θJA) is 33 °C/W, and junction-to-case (θJC) is 1.8 °C/W. For sustained 90 W/port operation, PCB layout must follow Microchip's recommended thermal pad array (Figure 3-3) and use ≥65% solder paste coverage on the ePAD.
