Product details

Overview

PD69200R-016703 from Microchip Technology is a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller IC based on the NXP MKL15Z128VFM4 ARM® Cortex-M0+ core. It supports IEEE 802.3af/at/bt and HDBaseT PoH standards, delivers up to 90 W per port using four-pair power, and operates in Class, Dynamic, or Static power management modes. It interfaces with PD69208T4/PD69204T4/PD69208M PoE managers via SPI and supports host control via UART or I2C.

For engineers reviewing the PD69200R-016703 datasheet, PD69200R-016703 pinout, PD69200R-016703 application, or PD69200R-016703 equivalent, key selection criteria include IEEE 802.3bt compliance, 32-pin QFN package compatibility, firmware-upgradable architecture, dual communication interface (UART/I2C), and integration readiness with Microchip's PoE manager family for enterprise switch and midspan PSE designs.

Technical Context

The PD69200R-016703 implements a hierarchical PoE control architecture: it acts as the system-level controller coordinating up to 12 cascaded PoE managers (e.g., PD69208T4) to manage 48 logical ports. Its firmware-pre-programmed and field-upgradeable-handles IEEE 802.3bt classification, legacy detection, fast/perpetual PoE, and port prioritization across 16 configurable power banks.

Communication is segmented: SPI (1 MHz, slave mode) links exclusively to PoE managers for real-time port control and telemetry, while UART (19.2 kbps, 15-byte protocol) or I2C (400 kHz, clock-stretch supported) connects to the host microprocessor for system-level configuration, status reporting, and interrupt-driven event handling via xINT_OUT and xI2C_MESSAGE_READY signals.

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; newer SAM D21-based design; higher firmware revision baseline.	Targeted for new designs only; same system integration but improved long-term availability and toolchain support.	Select PD69220 for greenfield projects requiring extended lifecycle and Microchip's latest SAM D21 ecosystem.
PD69210	Also SAM D21-based; differs in detection method (IEEE 802.3-only vs. PD69200's dual-mode detection).	Optimized for pure IEEE-compliant environments; lacks pre-standard legacy detection required in mixed-vendor deployments.	Choose PD69210 only when legacy device support is unnecessary and IEEE-only compliance suffices.

Compared with PD69220 and PD69210, the PD69200R-016703 provides verified backward compatibility with existing NXP-based designs, retains dual-mode detection for heterogeneous networks, and remains available for continuity - making it the sole option for sustaining legacy PoE switch platforms.

FAQ

What IEEE PoE standards does the PD69200R-016703 support?

The PD69200R-016703 supports IEEE 802.3af (15.4 W), 802.3at (30 W), 802.3bt (up to 90 W per port), and HDBaseT PoH standards. It implements full Type 3 and Type 4 classification, legacy detection, and fast/perpetual PoE features - ensuring interoperability with all compliant Powered Devices and backward compatibility with pre-standard equipment. This multi-standard support is embedded in its pre-programmed firmware and verified per DS00003460B.

How does the PD69200R-016703 interface with PoE managers like PD69208T4?

The PD69200R-016703 interfaces with PD69208T4, PD69204T4, and PD69208M PoE managers exclusively via a dedicated 1 MHz SPI bus (pins ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO). Each manager is assigned a unique address (0–11), allowing the PD69200R-016703 to coordinate up to 12 managers for 48 logical ports. This SPI link handles real-time port control, current/voltage telemetry, and fault reporting - separate from host-facing UART/I2C communication.

Can the firmware of PD69200R-016703 be updated in the field?

Yes, the firmware of PD69200R-016703 is field-upgradeable via its UART or I2C interface using the 15-byte protocol. Firmware updates enable support for new standards, bug fixes, or custom profile modifications - all without requiring reprogramming hardware. The default profiles are pre-loaded at factory, and Microchip provides a configuration tool and Serial Communication Protocol guide to facilitate updates, as documented in DS00003460B and AN3361.

What is the role of the I2C_ADDR_MEAS pin on PD69200R-016703?

The I2C_ADDR_MEAS pin (Pin 22) on PD69200R-016703 serves a dual purpose: it selects between UART and I2C host interface modes, and sets the 7-bit I2C slave address (0x04 to 0x3C) via an external resistor ladder. Voltage thresholds between 0 V and 3.3 V determine the mode and address - for example, 0.41–0.62 V configures I2C address 0x08. This eliminates the need for additional address-select pins and simplifies board design for multi-controller systems.

Does PD69200R-016703 support LED status indication for PoE ports?

Yes, PD69200R-016703 supports LED stream control via three dedicated outputs: xLED_CS (chip select), xLED_LATCH (latch), and xLED_OE (output enable), all active-low. These signals drive multiplexed LED arrays to display per-port PoE status (e.g., powered, fault, class) without consuming host MCU GPIOs. The LED stream is synchronized with SPI communication to the PoE managers, enabling coordinated visual feedback across all 48 ports in large-scale deployments.
