Product details

Overview

PD69200C-017221 from Microchip Technology is a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller IC based on the NXP MKL15Z128VFM4 ARM® Cortex-M0+ core, supporting IEEE 802.3af/at/bt and HDBaseT PoH standards, delivering up to 90 W per port via four-pair operation, and operating across –40 °C to +85 °C in a 32-pin 5 mm × 5 mm QFN package for enterprise switch and midspan PSE designs.

For engineers reviewing the PD69200C-017221 datasheet, PD69200C-017221 pinout, PD69200C-017221 application, or PD69200C-017221 equivalent, key selection criteria include IEEE 802.3bt compliance, SPI/I2C/UART host interface flexibility, 45 W two-pair / 90 W four-pair power capability, 16-bank power management, and pin compatibility with PD69220 for legacy design continuity.

Technical Context

The PD69200C-017221 implements a hierarchical PoE control architecture: it communicates with PD69208T4/PD69204T4/PD69208M PoE managers via 1 MHz SPI to manage up to 48 logical ports across 12 cascaded devices, while interfacing with the host processor via configurable I2C (400 kHz, clock-stretch supported) or UART (19.2 kbps, 15-byte protocol) for system-level telemetry and configuration.

Firmware is pre-programmed and field-upgradeable; default profiles support Class (LLDP), Dynamic, and Static power management modes; analog input pin I2C_ADDR_MEAS selects between UART/I2C operation and sets one of 16 I2C addresses (0x4–0x3C), enabling multi-controller addressing on shared buses without external address pins.

Key Specifications

Parameter	Value and Actual Design Meaning

Pinout & Package

PD69200C-017221 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 performance. The package complies with MSL3, RoHS, and Pb-free reflow standards (peak 260 °C).

Pin/Terminal	Circuit Role	Design Meaning
1–2, 9, 14, 17–18, 23, 29	Reserved	Unused pins; must be left open (1, 17–18), pulled to 3.3 V (2, 9, 14), or grounded (23, 29) per datasheet guidance to prevent floating inputs.
3–6 (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO)	SPI Interface to Manager	Controls PD69208T4/PD69204T4/PD69208M managers at 1 MHz; chip select active-low, clock output, full-duplex data path for port-level power and status commands.
7, 15 (VDDA, VDD)	Digital & Analog Supply	Separate 3.3 V supply pins for analog and digital domains - reduces noise coupling between ADC-based detection circuits and digital logic.
8, 16 (VSSA, VSSD)	Analog & Digital Ground	Independent ground returns minimize ground bounce during high-current port switching transients and improve detection accuracy.
11–12 (UART0_RX, UART0_TX)	UART Host Interface	19.2 kbps bidirectional link using 15-byte protocol; pull-up required on RX for reliable command reception in noisy switch environments.
20–21 (I2C0_SCL, I2C0_SDA)	I2C Host Interface	400 kHz I2C bus with clock stretch support; enables multi-master arbitration and deterministic timing for telemetry reads in real-time monitoring systems.
22 (I2C_ADDR_MEAS)	Analog Address Selection	Voltage divider input setting I2C address (0x4–0x3C) or selecting UART mode - eliminates external address jumpers and simplifies board layout.
24–25 (xI2C_MESSAGE_READY, xINT_OUT)	Interrupt & Ready Signaling	Active-low handshake signals: xI2C_MESSAGE_READY indicates valid reply ready for read; xINT_OUT flags port events (fault, classification, power change) without polling overhead.
26–28 (xLED_CS, xLED_LATCH, xLED_OE)	LED Stream Control	Three-wire interface driving LED status indicators per port - supports dynamic color/status encoding for visual diagnostics without MCU intervention.
30 (FAN_CONTROL)	Fan Driver Output	Active-high logic signal directly drives external fan controller ICs or MOSFET gate - enables thermal throttling response tied to PoE power draw and ambient temperature.
31 (xDISABLE_PORTS)	Global Port Shutdown	Active-low hardware kill switch - immediately disables all PoE ports during emergency conditions (overtemperature, AC loss) independent of firmware state.
32 (xSys_OK/LED System OK)	System Validity Indicator	Configurable active-low output reflecting overall PSE health; software-maskable per subsystem (SPI, I2C, power bank) for precise fault localization.

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 IEEE 802.3bt support; based on Microchip SAM D21 (ARM Cortex-M0+) instead of NXP MKL15Z128.	Targeted for new designs; offers updated toolchain support and longer-term availability than PD69200.	Select PD69220 for greenfield projects requiring extended lifecycle assurance and SAM D21 ecosystem integration.
PD69210	Also SAM D21-based; supports same standards and interfaces but lacks four-pair 90 W capability - limited to 60 W per port (two-pair only).	Optimized for cost-sensitive, lower-power applications such as 8- or 16-port desktop injectors or VoIP-only deployments.	Choose PD69210 where 45 W per port suffices and BOM cost reduction is prioritized over maximum power density.

Compared with PD69220 and PD69210, the PD69200C-017221 provides proven field reliability in existing infrastructure while retaining full 90 W four-pair capability - making it the preferred choice for maintaining legacy designs without sacrificing IEEE 802.3bt compliance or cascading scalability.

FAQ

What IEEE PoE standards does the PD69200C-017221 support?

The PD69200C-017221 supports IEEE 802.3af (Type 1), 802.3at (Type 2), 802.3bt (Type 3 and Type 4), and HDBaseT Power over HDBaseT (PoH). It delivers up to 45 W on two pairs and 90 W on four pairs per port, meeting full Class 8 compliance under 802.3bt. This enables interoperability with all standard-compliant Powered Devices including high-power wireless access points and PTZ cameras.

Is the PD69200C-017221 pin-compatible with other Microchip PSE controllers?

Yes, the PD69200C-017221 is pin-compatible with the PD69220, sharing identical pinout, package (32-pin QFN, 5 mm × 5 mm), and feature set. However, it is not pin-compatible with the PD69210, which uses a different package and pin assignment. Designers can migrate existing PD69200C-017221 layouts to PD69220 without PCB changes, preserving mechanical and routing integrity.

How does the PD69200C-017221 interface with PoE manager ICs like PD69208T4?

The PD69200C-017221 interfaces with PD69208T4, PD69204T4, and PD69208M PoE managers via a dedicated 1 MHz SPI bus using pins ESPI_xCS (3), ESPI_SCK (4), ESPI_MOSI (5), and ESPI_MISO (6). Each manager is assigned an address (0–11), allowing up to 12 managers to be cascaded for 48 logical ports. Communication follows a defined packet structure with control byte, register address, and data fields.

Can firmware on the PD69200C-017221 be updated in the field?

Yes, firmware on the PD69200C-017221 is field-upgradeable via either the I2C or UART interface using the 15-byte communication protocol. Microchip provides a configuration tool and Serial Communication Protocol guide to support updates. Firmware version is encoded in the part number (e.g., "C-017221" reflects revision and parameter options), and upgrades retain full IEEE 802.3bt and PoH functionality.

What is the role of the I2C_ADDR_MEAS pin (pin 22) on the PD69200C-017221?

The I2C_ADDR_MEAS pin (22) on the PD69200C-017221 serves dual functions: it selects between UART and I2C host interface modes, and sets the 7-bit I2C address (0x4 to 0x3C) via an external resistor voltage divider. This eliminates the need for physical jumpers or address pins, simplifying board layout and enabling flexible multi-controller addressing on shared I2C buses in complex systems.
