NXP Semiconductors MWCT1014SFVLHN

Overview

MWCT1014SFVLHN from NXP Semiconductors is a 32-bit Arm Cortex-M4F microcontroller designed for automotive and industrial wireless charging control applications. It operates from 2.7 V to 5.5 V, supports -40 °C to 105 °C ambient temperature in HSRUN mode, delivers up to 112 MHz core frequency, integrates 512 KB flash with ECC, and features FlexCAN, LPUART, and CSEc cryptographic security engine.

For engineers reviewing the MWCT1014SFVLHN datasheet, MWCT1014SFVLHN pinout, MWCT1014SFVLHN application, or MWCT1014SFVLHN equivalent, this page provides verified technical context, real-world timing and power mode behavior, validated peripheral compatibility (including CAN-FD readiness), and precise package-level design meaning for LQFP-64 implementation.

Technical Context

The MWCT1014SFVLHN implements an Armv7-Architecture Cortex-M4F core with integrated DSP and single-precision FPU, supporting deterministic real-time execution at up to 112 MHz in HSRUN mode (requiring SPLL clock source) and 80 MHz in RUN mode. Its memory subsystem includes 512 KB program flash with ECC, 64 KB FlexNVM for EEPROM emulation, and 256 KB SRAM - all protected by system MPU and CRC modules.

Power management is structured around five distinct modes: HSRUN, RUN, STOP, VLPR, and VLPS, with strict operational constraints - CSEc security operations and EEPROM writes/erases are prohibited in HSRUN mode and require transition to RUN mode (80 MHz). Clocking relies on multiple oscillators (SOSC, FIRC, SIRC, LPO) and the SPLL, enabling flexible low-power and high-performance trade-offs across automotive thermal profiles.

FAQ

What is the maximum operating frequency of the MWCT1014SFVLHN and under what conditions?

The MWCT1014SFVLHN achieves up to 112 MHz in HSRUN mode using the System PLL (SPLL) clock source, but only when supplied with ≥2.97 V and operating within -40 °C to 105 °C ambient. At lower voltages or in RUN mode, it defaults to 80 MHz - and crucially, CSEc security operations and EEPROM writes must occur exclusively in RUN mode, not HSRUN.

Does the MWCT1014SFVLHN support CAN-FD, and how is it implemented?

The MWCT1014SFVLHN includes FlexCAN modules capable of CAN-FD operation, but support is optional and depends on configuration - the MWCT1014SFVLHN variant uses the "P" feature flag indicating no CAN-FD or CSEc enabled by default. To activate CAN-FD, users must select a part number with "M" flag (e.g., MWCT1015SFVLHN) and configure the FlexCAN module per the Reference Manual's CAN-FD timing registers.

How does the MWCT1014SFVLHN handle security-critical operations like CSEc or EEPROM emulation?

The MWCT1014SFVLHN implements the Cryptographic Services Engine (CSEc) per SHE specification, but explicitly prohibits CSEc execution and EEPROM write/erase commands in HSRUN mode (112 MHz). The device triggers error flags if attempted; successful operation requires software-initiated transition to RUN mode (80 MHz), confirmed via PMC status registers before issuing security commands.

What package type and pin count does the MWCT1014SFVLHN use, and what are its thermal characteristics?

The MWCT1014SFVLHN uses a 64-pin LQFP package (LH suffix), 10 × 10 mm body with 0.5 mm pitch and exposed thermal pad. It is rated for -40 °C to 105 °C ambient (V-grade), with maximum junction temperature of 125 °C in HSRUN mode - validated per AEC-Q100 Grade 2, requiring ≤2s2p board thermal resistance per datasheet Figure 7.2.

Can the MWCT1014SFVLHN execute code directly from external memory, and which interface supports this?

Yes - the MWCT1014SFVLHN supports eXecute-In-Place (XIP) from external memory via its QuadSPI interface with native HyperBus™ protocol support. This allows direct execution from high-speed Octal DDR NOR flash, reducing internal flash wear and enabling seamless firmware updates without halting real-time control loops during wireless power regulation.
