Product details
Overview
MWCT1012VLFR from NXP Semiconductors is a WPC Qi-compliant wireless power transmitter controller IC designed for industrial and consumer extended power profile (EPP) charging systems. It integrates digital demodulation, FSK/ASK two-way communication, calibrated foreign object detection (FOD), rail voltage/phase/duty cycle control, and supports 5–24 V DC input. It operates with 100 MHz bus clock, 3.3 V supply, and delivers <1.2 mA in LPSTOP mode for ultra-low standby power.
For engineers reviewing the MWCT1012VLFR datasheet, MWCT1012VLFR pinout, MWCT1012VLFR application, or MWCT1012VLFR equivalent, this page provides verified technical context, validated pin functions, confirmed EPP transmitter role, real-world FOD and communication implementation details, and alternative parts with documented interface and clock differences.
Technical Context
The MWCT1012VLFR implements a software-configurable, fixed-frequency wireless power transmitter architecture compliant with WPC Qi Extended Power Profile (EPP). It uses integrated digital demodulation to decode receiver packets and supports three closed-loop control methods-rail voltage, phase difference, and duty cycle-to regulate power delivery while maintaining EMI compliance via dithering and slew control.
It features dual-clock domain operation: 100 MHz bus clock (confirmed for MWCT1012 per datasheet Table 5 Note 10), 8 MHz internal relaxation oscillator (±1.5% over 0–105°C), and 32 kHz VLPRUN clock. Its protection suite includes over-voltage, over-current, over-temperature, and calibrated Q-factor–based FOD using analog front-end sensing and digital processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Wireless Standard | WPC Qi Extended Power Profile (EPP) compliant transmitter controller - enables interoperable 15 W+ charging with certified receivers. |
| Input Voltage Range | 5 V to 24 V DC - supports wide-range industrial and automotive power supplies without external regulators. |

Pinout & Package
MWCT1012VLFR is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad, per Addendum 10.2 in WCT101XDS Rev. 1.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA | Digital & analog supply inputs | Must be decoupled independently; ΔVDD ≤ ±0.1 V ensures ADC accuracy and stable core operation. |
| XTAL / EXTAL | Crystal oscillator terminals | Supports 4–16 MHz external crystal; enables precise timing for FSK demodulation and packet synchronization. |
| FSK_IN / ASK_OUT | Two-way comms I/O | FSK_IN receives modulated signal from receiver; ASK_OUT transmits amplitude-shift keying back to receiver for handshake. |
| GPIO[0:15] | Configurable general-purpose I/O | Support interrupt generation, LED status indication, and external FET gate drive control with programmable slew rate. |
| SPI_MOSI / MISO / SCK / SS | SPI interface signals | Enable high-speed configuration and real-time telemetry transfer between host MCU and MWCT1012VLFR firmware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless power transmitter controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MWCT1011VLHSTx | 50 MHz max bus clock; no SAR ADC; lower thermal rating (TA = –40 to 85 °C) | Limited to baseline power profile (BPP) and low-power consumer chargers; unsuitable for EPP or industrial ambient temps. | Select MWCT1011VLHSTx only when cost sensitivity outweighs EPP capability and extended temperature range. |
| MWCT1013VLHSTx | Includes 12-bit SAR ADC; supports higher-resolution analog sensing for advanced FOD and coil current monitoring. | Better suited for high-accuracy industrial FOD systems requiring direct coil current measurement and adaptive tuning. | Choose MWCT1013VLHSTx when system-level FOD validation requires >10-bit analog resolution beyond MWCT1012VLFR's cyclic ADC. |
Compared with MWCT1011VLHSTx, MWCT1012VLFR enables EPP-grade power delivery and wider temperature operation; compared with MWCT1013VLHSTx, it trades SAR ADC capability for lower cost and identical EPP control firmware compatibility.

FAQ
What wireless charging standard does the MWCT1012VLFR support?
The MWCT1012VLFR supports the Wireless Power Consortium (WPC) Qi Extended Power Profile (EPP) specification as a transmitter controller. It is fully compliant with power class 0 and enables interoperable 15 W+ charging with certified receivers. The MWCT1012VLFR implements mandatory FSK/ASK two-way communication, calibrated foreign object detection, and power negotiation protocols defined in the latest WPC specification referenced in WCT101XDS Rev. 1.2.
Does the MWCT1012VLFR require an external crystal oscillator?
Yes, the MWCT1012VLFR requires an external 4–16 MHz crystal connected to XTAL/EXTAL pins for precise timing of FSK demodulation and packet transmission. While it includes an internal relaxation oscillator (8 MHz ±1.5%), the datasheet specifies that the crystal oscillator is mandatory for WPC-compliant operation due to tighter frequency stability requirements. The MWCT1012VLFR's pinout and electrical specs in WCT101XDS Rev. 1.2 confirm XTAL/EXTAL as dedicated, non-optional inputs.
How does the MWCT1012VLFR implement foreign object detection (FOD)?
The MWCT1012VLFR implements FOD using a calibrated Q-factor detection framework combined with power-loss modeling. It measures resonant tank impedance changes via its integrated ADC and analog front end, then applies digital compensation algorithms to distinguish metallic objects from valid receivers. This method is explicitly documented in the WCT101XDS Rev. 1.2 Features section and requires no external calibration - the MWCT1012VLFR delivers production-ready FOD performance per WPC safety requirements.
What interfaces does the MWCT1012VLFR support for host MCU communication?
The MWCT1012VLFR supports CAN, I²C, SCI (asynchronous UART), and SPI host interfaces - all confirmed in the WCT101XDS Rev. 1.2 Features list and Pin Function Description table. Each interface is electrically isolated in the functional block diagram and mapped to dedicated pins (e.g., CANH/CANL, I²C_SCL/SDA, SCI_TXD/RXD, SPI_MOSI/MISO/SCK/SS). This multi-protocol support allows flexible integration with automotive body controllers (CAN), industrial PLCs (SCI), or cost-sensitive consumer MCUs (I²C).
Is the MWCT1012VLFR pin-compatible with other WCT101x variants?
No, the MWCT1012VLFR is not pin-compatible with MWCT1011VLHSTx or MWCT1013VLHSTx. Although all share the same 64-pin LQFP package outline, WCT101XDS Rev. 1.2 Addenda confirm distinct pin function allocations - for example, MWCT1013VLHSTx adds SAR ADC input pins not present on MWCT1012VLFR, and MWCT1011VLHSTx omits several high-speed GPIOs. PCB layout must be designed specifically for MWCT1012VLFR per its unique pinout in Section 4.3.
