Product details
Overview
PD69200C-016121 from Microchip Technology is a Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller IC designed to manage IEEE 802.3af/at/bt and HDBaseT PoH compliant power delivery across up to 48 logical ports via cascaded PoE managers. It integrates NXP MKL15Z128VFM4-based firmware, supports 45 W two-pair and 90 W four-pair per port, operates from -40°C to +85°C, and uses a 32-pin 5 mm × 5 mm QFN package. It serves in enterprise switches and industrial PoE midspans.
For engineers reviewing the PD69200C-016121 datasheet, PD69200C-016121 pinout, PD69200C-016121 application, or PD69200C-016121 equivalent, key selection criteria include IEEE 802.3bt compliance, SPI/I2C/UART host interface flexibility, 16-power-bank architecture, legacy detection support, and pin compatibility with PD69220 for migration paths.
Technical Context
The PD69200C-016121 implements a hierarchical PoE control architecture: it communicates with PD69208T4/PD69204T4/PD69208M PoE managers via 1 MHz SPI to drive up to 12 devices (48 ports), while interfacing with host microprocessors via UART (19.2 kbps) or I2C (400 kHz with clock stretch). Its firmware-pre-programmed and field-upgradeable-supports Class, Dynamic, and Static power management modes.
Hardware-level features include dedicated interrupt output (xINT_OUT), system OK indicator (xSys_OK), disable ports input (xDISABLE_PORTS), LED stream control (xLED_CS/xLED_LATCH/xLED_OE), and analog-configurable I2C address selection via I2C_ADDR_MEAS pin. The device relies on external 3.3 V supply (VDD/VDDA) and integrates ESD protection (±2000 V HBM).
Key Specifications

Pinout & Package
PD69200C-016121 is housed in a 32-pin, 5 mm × 5 mm QFN package with exposed thermal pad (ePAD) requiring connection to VSSA for thermal performance. The package is RoHS-compliant, MSL3 rated, and supports Pb-free reflow up to 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–2, 9, 13–14, 17–18, 23, 29 | Reserved / Analog_IN / Oscillator | Unused or factory-configured pins; some require pull-up/pull-down per AN3361; oscillator pins must be left open |
| 3–6 (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO) | SPI Interface to PoE Manager | Drives PD69208T4/PD69204T4/PD69208M managers at 1 MHz; active-low chip select, bidirectional data |
| 7, 15 (VDDA, VDD) | Digital & Analog Supply | Independent 3.3 V inputs; decoupling required per layout guidelines to ensure stable PoE sequencing |
| 8, 16, ePAD (VSSA, VSSD) | Analog & Digital Ground | Separate ground planes recommended; ePAD must connect to VSSA with sufficient copper mass for θJC = 1.8 °C/W |
| 11–12 (UART0_RX, UART0_TX) | UART Host Interface | 19.2 kbps, 8N1 protocol; RX requires 10 kΩ pull-up; used for telemetry, configuration, and firmware updates |
| 20–21 (I2C0_SCL, I2C0_SDA) | I2C Host Interface | 400 kHz max with clock stretch support; bidirectional communication for host-controlled PoE state monitoring |
| 22 (I2C_ADDR_MEAS) | Analog Address Selection | Voltage level sets I2C address (0x04–0x3C) or selects UART mode; resistor-divider network defines function |
| 24–25 (xI2C_MESSAGE_READY, xINT_OUT) | Host Synchronization & Event Alert | Active-low handshake signals: one indicates ready I2C reply; the other asserts on port fault, detection, or thermal event |
| 26–28 (xLED_CS, xLED_LATCH, xLED_OE) | LED Stream Control | Drive external LED arrays for port status indication; synchronous latching enables multi-port visual feedback |
| 30 (FAN_CONTROL) | Fan Driver Output | Active-high logic signal to control cooling fan based on thermal or power-load conditions |
| 31 (xDISABLE_PORTS) | Global Port Shutdown | Active-low input that immediately disables all PoE ports - critical for emergency thermal or fault response |
| 32 (xSys_OK/LED System OK) | System Validity Indicator | Active-low output reflecting firmware health and PoE subsystem readiness; configurable via software mask |

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, identical feature set, SAM D21-based firmware - newer silicon platform with enhanced debug and lower power idle states | Recommended for new designs; supports same 48-port cascade topology but with updated GUI and API toolchain | Select PD69220 when starting fresh designs requiring latest Microchip PoE software stack and extended lifecycle support |
| PD69210 | SAM D21-based, supports same standards and port count, but lacks LED stream interface and has different interrupt mapping | Better suited for cost-sensitive, lower-feature PoE systems where visual port status is handled externally | Choose PD69210 where LED control is unnecessary and BOM cost optimization is prioritized over peripheral integration |
Compared with PD69200C-016121, PD69220 offers identical functionality with modern firmware infrastructure and longer-term roadmap alignment, while PD69210 trades LED stream and refined interrupt handling for reduced unit cost - making PD69200C-016121 optimal for legacy design continuity and field-upgradeable deployments.

FAQ
What IEEE PoE standards does the PD69200C-016121 support?
The PD69200C-016121 supports IEEE 802.3af (Type 1), 802.3at (Type 2), 802.3bt (Type 3 and Type 4), and HDBaseT Power over HDBaseT (PoH) standards. It delivers up to 45 W on two pairs and 90 W on four pairs per port, enabling full backward compatibility and next-generation high-power applications. This compliance is implemented in firmware and verified per DS00003460B.
Is PD69200C-016121 pin-compatible with any other Microchip PSE controllers?
Yes, PD69200C-016121 is explicitly stated as pin-compatible with PD69220 in the datasheet. Both share identical 32-pin QFN footprints, SPI/I2C/UART interface pin assignments, and power/ground layouts. However, PD69200C-016121 uses NXP Kinetis-based firmware, whereas PD69220 uses Microchip SAM D21 - requiring firmware and toolchain adjustments despite mechanical and electrical compatibility.
How does the PD69200C-016121 handle firmware updates in the field?
The PD69200C-016121 supports field-upgradable firmware via its I2C or UART interface using a 15-byte protocol. Updates are performed without hardware modification, leveraging Microchip's provided Serial Communication Protocol guide and configuration tools. Firmware version is encoded in the part number (e.g., "C-016121" reflects revision and parameter options), and updates preserve configuration settings unless explicitly reset.
What is the role of the I2C_ADDR_MEAS pin on PD69200C-016121?
The I2C_ADDR_MEAS pin (Pin 22) on PD69200C-016121 serves dual functions: selecting between UART and I2C host interfaces, and setting the 7-bit I2C slave address (0x04 to 0x3C) via an external resistor divider. Voltage thresholds defined in Table 1-2 determine mode and address - for example, 1.03–1.24 V selects I2C address 0x14. This eliminates need for additional configuration pins or straps.
Does PD69200C-016121 support legacy (non-standard) PoE device detection?
Yes, PD69200C-016121 includes built-in legacy detection support to identify pre-standard or non-IEEE-compliant Powered Devices (PDs), such as early VoIP phones and proprietary endpoints. This capability is implemented in firmware and activated automatically during signature detection phase, ensuring interoperability without requiring external circuitry or host intervention.
