Product details
Overview
PD69200R-034300 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 control unit in multi-port PSE systems paired with PD69208T4/PD69204T4/PD69208M managers.
For engineers reviewing the PD69200R-034300 datasheet, PD69200R-034300 pinout, PD69200R-034300 application, or PD69200R-034300 equivalent, key selection criteria include IEEE 802.3bt compliance, SPI/I2C/UART host interface flexibility, 16-power-bank architecture, fast/perpetual PoE support, and compatibility with legacy detection and LED stream control.
Technical Context
The PD69200R-034300 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 configurable 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 assignment, and cascade topology up to 12 devices.
Hardware design centers on dual supply domains (VDD/VDDA), integrated analog input for I²C address selection (pin 22), active-low interrupt signaling (xINT_OUT), system status indication (xSys_OK), and dedicated LED stream control outputs (xLED_CS/xLED_LATCH/xLED_OE). Thermal performance is managed via an exposed thermal pad (ePAD) connected to VSSA, with θJA = 33 °C/W and θJC = 1.8 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standards Compliance | IEEE 802.3af, 802.3at, 802.3bt, and HDBaseT PoH - enables interoperability with Class 0–8 PDs and four-pair high-power delivery. |
| Max Port Power | 45 W (two-pair), 90 W (four-pair) - supports full Type 4 (802.3bt) operation per port with appropriate manager ICs. |
| Port Scalability | Cascades up to 12 PD69200R-034300-compatible controllers for 48 logical ports - eliminates need for centralized master controller in large switches. |
| Power Bank Architecture | 16 independent power banks across four supplies - allows granular power budgeting and fault isolation per bank group. |
| Host Interface Options | UART (19.2 kbps, 8N1), I²C (7-bit address, clock stretch required), or SPI (1 MHz, slave mode to manager) - provides flexible integration with diverse host MCUs. |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial-grade Ethernet infrastructure deployments including unmanaged switches and midspans. |
| ESD Rating | HBM ±2000 V, CDM ±500 V - meets robustness requirements for PoE system assembly and field service environments. |
Pinout & Package
PD69200R-034300 is housed in a 32-pin, 5 mm × 5 mm QFN package with exposed thermal pad (ePAD), RoHS-compliant, MSL3 rated. The ePAD must be soldered to VSSA with sufficient copper area for thermal dissipation (θJA = 33 °C/W).
| 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 (e.g., Pin 2: 10 kΩ to 3.3 V; Pin 14: to 3.3 V or GND). |
| 3–6 (ESPI_xCS, ESPI_SCK, ESPI_MOSI, ESPI_MISO) | SPI Interface to Manager IC | Controls PD69208T4/PD69204T4/PD69208M managers at 1 MHz; ESPI_xCS is active-low chip select with external pull-up. |
| 11–12 (UART0_RX, UART0_TX) | UART Host Interface | Full-duplex 19.2 kbps communication; UART0_RX requires external pull-up; both use 15-byte protocol for telemetry and commands. |
| 20–21 (I2C0_SCL, I2C0_SDA) | I²C Host Interface | 400 kHz bidirectional bus with mandatory clock stretch support; external pull-ups required per AN3361. |
| 22 (I2C_ADDR_MEAS) | Analog Input for Interface Selection | Voltage level sets UART vs. I²C mode and selects one of 16 I²C addresses (0x04–0x3C); resistor divider determines function. |
| 24–25 (xI2C_MESSAGE_READY, xINT_OUT) | Interrupt & Status Signaling | xI2C_MESSAGE_READY (active low) signals ready data for host read; xINT_OUT (active low) flags preconfigured events (e.g., port fault, power limit exceeded). |
| 26–28 (xLED_CS, xLED_LATCH, xLED_OE) | LED Stream Control Outputs | Drive external LED drivers for per-port status indication; all active-low with precise timing coordination for daisy-chained LEDs. |
| 30 (FAN_CONTROL) | Fan Driver Output | Active-high logic signal to control cooling fan speed or enable based on thermal or power load conditions. |
| 31 (xDISABLE_PORTS) | Global Port Shutdown Input | Active-low input that immediately disables all PoE ports - used for emergency shutdown or system-level safety interlock. |
| 32 (xSys_OK/LED System OK) | System Validity Indicator | Active-low output reflecting overall system health; behavior configurable via software mask (e.g., asserts on firmware boot success or critical error). |

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 qualification. | Identical functional scope; recommended for new designs per Microchip documentation. | Select PD69220 for production ramp of new platforms; PD69200R-034300 remains valid for legacy design continuity and obsolescence mitigation. |
| 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 PD69200R-034300. | Choose PD69210 only when migrating to SAM D21 ecosystem; avoid for drop-in replacement due to architectural divergence. |
Compared with PD69220, PD69200R-034300 offers identical functionality but reflects earlier silicon revision and NXP-based firmware foundation; compared with PD69210, it avoids ARM Cortex-M0+ migration overhead but retains legacy toolchain dependencies - making PD69200R-034300 optimal for sustaining engineering and long-lifecycle infrastructure programs.

FAQ
What standards does the PD69200R-034300 support for Power over Ethernet?
The PD69200R-034300 supports IEEE 802.3af (PoE), 802.3at (PoE+), 802.3bt (PoE++), and HDBaseT Power over HDBaseT (PoH) standards. It enables full four-pair 90 W delivery per port under 802.3bt, with backward compatibility for legacy Class 0–3 devices. All compliance is implemented in firmware and verified per Microchip DS00003460B.
How does the PD69200R-034300 interface with PoE manager ICs like PD69208T4?
The PD69200R-034300 communicates with PD69208T4, PD69204T4, and PD69208M managers via a dedicated 1 MHz SPI slave interface using pins ESPI_xCS (Pin 3), ESPI_SCK (Pin 4), ESPI_MOSI (Pin 5), and ESPI_MISO (Pin 6). Each manager is assigned a unique address (0–11), and the PD69200R-034300 acts as SPI master to coordinate port power control and telemetry.
Can the PD69200R-034300 be upgraded in the field, and how?
Yes, the PD69200R-034300 supports field firmware upgrades via its UART or I²C host interface using the 15-byte protocol. Microchip provides configuration tools and API libraries for profile modification and firmware updates. The process requires no hardware changes and preserves existing system integration - confirmed in DS00003460B Section 1.1 and TN-140.
What is the purpose of Pin 22 (I2C_ADDR_MEAS) on the PD69200R-034300?
Pin 22 (I2C_ADDR_MEAS) is an analog input that determines both the host communication interface (UART or I²C) and the specific 7-bit I²C address (0x04 to 0x3C) via an external resistor divider. Voltage thresholds define mode and address - for example, 0.3 V selects UART, while 1.5 V selects I²C address 0x18. This eliminates need for additional configuration pins or jumpers.
Does the PD69200R-034300 support legacy PoE device detection?
Yes, the PD69200R-034300 supports legacy detection per IEEE 802.3af Clause 33.2.2, identifying non-standard powered devices using resistive signature measurement. This capability is enabled by internal circuitry and firmware, allowing interoperability with pre-standard or proprietary PDs without requiring external components.
