Overview
MWCT1023IFVLL from NXP Semiconductors is a 168 MHz Arm® Cortex®-M4 wireless power transmitter microcontroller with FPU, dual 12-bit ADCs (240 ns conversion), eFlexPWM (312 ps resolution), 256 KB flash, and dual FlexCAN interfaces. It serves as the intelligent control core in Qi-compliant 65 W wireless charging transmitters, managing resonant frequency tracking, foreign object detection, and multi-coil power delivery.
For engineers reviewing the MWCT1023IFVLL datasheet, MWCT1023IFVLL pinout, MWCT1023IFVLL application, or MWCT1023IFVLL equivalent, this page delivers verified technical context, real-world timing and analog performance data, confirmed package mapping to 100-pin LQFP, and validated alternative options for wireless power transmitter designs requiring high-resolution PWM control and integrated safety monitoring.
Technical Context
The MWCT1023IFVLL implements an Arm Cortex-M4 core with single-precision FPU and operates at up to 168 MHz, with core-to-timer clock ratio fixed at 1:2 above 100 MHz. Its analog subsystem includes two independent 12-bit cyclic ADCs (4.1 MSPS), four analog comparators with integrated 6-bit DACs, and one 12-bit DAC - all supported by programmable reference inputs and low-leakage wakeup capability.
Timing control is handled by the eFlexPWM module (4 sub-modules, 12 outputs, 312 ps resolution), two 8-channel FlexTimers (FTM0/FTM3), one 2-channel FlexTimer (FTM1), four PITs, two PDBs, and ENC - enabling precise phase-shifted gate drive for resonant LLC or Class-E power stages in wireless charging systems.
