NXP Semiconductors MWCT1015SFVMH

Overview

MWCT1015SFVMH from NXP Semiconductors is a pre-production Arm® Cortex-M4F microcontroller designed for wireless charging control applications, operating from 2.7 V to 5.5 V across –40 °C to 105 °C ambient, featuring 2 MB flash with ECC, 256 KB SRAM with ECC, and integrated CSEc cryptographic engine.

For engineers reviewing the MWCT1015SFVMH datasheet, MWCT1015SFVMH pinout, MWCT1015SFVMH application, or MWCT1015SFVMH equivalent, this page delivers verified specifications, package mapping (100-pin LQFP), functional pin roles, safety-critical power mode constraints, and validated alternative parts for automotive-grade wireless charging system design.

Technical Context

The MWCT1015SFVMH implements an Armv7-Architecture-based Cortex-M4F core with single-precision FPU and DSP extensions, supporting up to 112 MHz in HSRUN mode (1.25 DMIPS/MHz) and 80 MHz in RUN mode - where CSEc security operations and EEPROM emulation are exclusively permitted. Its clock system integrates SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz).

Power management includes five distinct modes (HSRUN, RUN, STOP, VLPR, VLPS), with strict mode-dependent restrictions: CSEc execution, FlexNVM writes, and EEPROM emulation are prohibited in HSRUN mode and require transition to RUN mode (80 MHz). Memory subsystem features ECC-protected 2 MB flash, 64 KB FlexNVM, 256 KB SRAM, and 4 KB FlexRAM usable as SRAM or EEPROM emulation.

FAQ

What is the maximum operating frequency of the MWCT1015SFVMH and under which conditions?

The MWCT1015SFVMH achieves up to 112 MHz in HSRUN mode using the System PLL (SPLL), but CSEc cryptographic operations and FlexNVM EEPROM emulation are prohibited at this frequency. These functions require switching to RUN mode at 80 MHz. The device's Arm Cortex-M4F core delivers 1.25 Dhrystone MIPS per MHz across both modes, with verified timing performance documented in the Rev. 5 datasheet.

Does the MWCT1015SFVMH support CAN-FD, and how is it implemented?

Yes, the MWCT1015SFVMH includes three FlexCAN modules with optional CAN-FD support enabled via configuration fuse settings. CAN-FD operation is validated per ISO 11898-1 CD specification and supports data rates up to 5 Mbps in the flexible data phase. This capability is essential for automotive diagnostic communication in wireless charging ECUs, and its implementation is confirmed in the Feature Comparison table of the MWCT101XS Data Sheet Rev. 5.

How does the MWCT1015SFVMH handle security-critical operations like CSEc execution?

The MWCT1015SFVMH implements the Cryptographic Services Engine (CSEc) per the Secure Hardware Extension (SHE) Functional Specification. However, CSEc commands - including key generation, AES encryption, and secure boot verification - trigger error flags if executed in HSRUN mode (112 MHz). The device must transition to RUN mode (80 MHz) before initiating any CSEc operation, as explicitly stated in multiple sections of the datasheet, including Power Management and Block Diagram footnotes.

What memory protection mechanisms are available on the MWCT1015SFVMH?

The MWCT1015SFVMH uses NXP's system-level Memory Protection Unit (System MPU), implemented at the Crossbar Switch to enforce access rights for both CPU and eDMA masters. Unlike Arm Core MPU, this system MPU protects all memory regions - including flash, SRAM, and peripherals - against unauthorized access. It supports region-based permissions (read/write/execute) and is integral to ASIL-B compliance, with configuration details provided in the MWCT101xS Series Reference Manual.

Is the MWCT1015SFVMH pin-compatible with other devices in the MWCT101xS family?

Yes - all MWCT101xS devices sharing the same package (e.g., 100-pin LQFP) are pin-to-pin compatible, as confirmed in the Feature Comparison section of the datasheet. The MWCT1015SFVMH uses the 100-pin LQFP package (MH suffix), matching pin count, signal assignment, and power/ground layout with MWCT1014SFVMH and MWCT1016SFVMH. This enables hardware reuse across performance tiers without PCB redesign.

What ADC capabilities does the MWCT1015SFVMH provide for wireless charging sensing?

The MWCT1015SFVMH integrates two independent 12-bit SAR ADC modules, each supporting up to 32 analog inputs and 1 MSPS sampling rate. These ADCs are used for real-time monitoring of primary/secondary coil currents, voltage waveforms, and temperature sensors. Their performance is specified across 2.7–5.5 V supply and –40 °C to 105 °C, with dedicated VREFH/VREFL pins and 100 nF decoupling (CREF) required for full 12-bit accuracy - details confirmed in Sections 6.4.1 and 4.4 of the datasheet.
