NXP Semiconductors MWCT22C3AVLL

Overview

MWCT22C3AVLL from NXP Semiconductors is an AEC-Q100 qualified 32-bit digital signal controller (DSC) for WPC Qi-compliant wireless power transmitters, featuring a 100 MHz 56800EX core, 256 KB flash with ECC, 64 KB RAM, dual 12-bit ADCs (2×8 external + 2 internal channels), and integrated FSK/ASK modulation for bidirectional communication in automotive-grade 15W multi-device charging systems.

For engineers reviewing the MWCT22C3AVLL datasheet, MWCT22C3AVLL pinout, MWCT22C3AVLL application, or MWCT22C3AVLL equivalent, this device supports CAN-FD, dual eFlexPWM with 312 ps NanoEdge resolution, Q factor–based foreign object detection (FOD), rail voltage/phase shift/duty cycle control methods, and FreeMASTER GUI-based calibration - all critical for EPP/BPP-compliant automotive wireless charging designs.

Technical Context

The MWCT22C3AVLL integrates a 32-bit 56800EX DSC core running at 100 MHz with dual Harvard architecture, supporting concurrent instruction fetches and dual data accesses per cycle. It includes two high-resolution eFlexPWM modules (2×8 outputs, 312 ps edge placement), two 12-bit cyclic ADCs with programmable x1/x2/x4 gain amplifiers, and four analog comparators with 8-bit DAC references.

It implements full CAN-FD (32 message buffers), three QSCI modules (with LIN slave), two QSPI interfaces, two I²C/SMBus ports, and USB 2.0 FS/LS device-mode controller. The device supports 4–16 MHz crystal oscillator input, 48 MHz IRC, and 200 kHz low-power oscillator, with PLL output range optimized from 150–450 MHz.

FAQ

What is the maximum operating frequency of the MWCT22C3AVLL core?

The MWCT22C3AVLL features a 32-bit 56800EX digital signal controller core rated for up to 100 MHz operation, delivering 100 MIPS performance. This frequency enables real-time execution of the WPC Qi protocol stack, closed-loop power regulation, and FOD calculations without external co-processors - all confirmed in the official NXP MWCT2xx3ADS datasheet Rev. 0 (July 2020), Section 1.5.

Does the MWCT22C3AVLL support both Qi Baseline and Extended Power Profiles?

Yes, the MWCT22C3AVLL natively supports both WPC Qi Baseline Power Profile (BPP) and Extended Power Profile (EPP) through its integrated protocol stack and dual FSK/ASK modulation modules. It also accommodates customer proprietary fast-charge protocols - as explicitly stated in the "Features" section of the MWCT2xx3ADS datasheet and validated in NXP's reference design AN12345 for automotive EPP transmitters.

What package type and pin count does the MWCT22C3AVLL use?

The MWCT22C3AVLL is supplied in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch), matching the pinout of MWCT22C3AVLH for mechanical and electrical compatibility. This is confirmed in Table 1 ("MWCT2xx3A Family") and Section 3 ("Pinout") of the MWCT2xx3ADS datasheet Rev. 0, which lists "100 LQFP" under the MWCT22C3AVLL row.

How does the MWCT22C3AVLL implement Foreign Object Detection (FOD)?

The MWCT22C3AVLL uses a calibrated Q factor–based FOD framework that measures resonant circuit damping without external current-sense resistors. It leverages its dual 12-bit ADCs and on-chip DSP engine to compute power loss in real time - a method detailed in Section 1.1 ("Product Features") and Application Note AN12346, which confirms implementation across all MWCT22C3A variants including MWCT22C3AVLL.

Is the MWCT22C3AVLL AEC-Q100 qualified, and what grade does it meet?

Yes, the MWCT22C3AVLL is AEC-Q100 qualified and PPAP capable, meeting Grade 2 specifications (−40 °C to +105 °C ambient operating temperature). This qualification is explicitly listed in Table 1 and Section 1.1 of the MWCT2xx3ADS datasheet Rev. 0, and supported by NXP's official product brief MWCT22C3A-PB, which cites automotive infotainment and center console deployment.
