NXP Semiconductors MWCT1015SFVLLPR

Overview

MWCT1015SFVLLPR from NXP Semiconductors is a 32-bit Arm Cortex-M4F microcontroller designed for automotive 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 2 MB ECC-protected flash and 256 KB ECC SRAM, and features FlexCAN with optional CAN-FD support.

For engineers reviewing the MWCT1015SFVLLPR datasheet, MWCT1015SFVLLPR pinout, MWCT1015SFVLLPR application, or MWCT1015SFVLLPR equivalent, key selection considerations include its ASIL-B capable safety architecture, CSEc cryptographic engine, dual 12-bit ADCs with 32-channel input capability, low-power timer suite (LPTMR, LPIT, PDB), and support for HyperBus™ via QuadSPI interface.

Technical Context

The MWCT1015SFVLLPR implements an Armv7-Architecture Cortex-M4F core with integrated DSP extensions and single-precision FPU, enabling real-time signal processing for resonant wireless power control loops. Its clock system combines SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz) to support dynamic mode switching between RUN (80 MHz) and HSRUN (112 MHz).

Power management includes five distinct modes-HSRUN, RUN, STOP, VLPR, VLPS-with PMC-enforced restrictions: CSEc security operations and EEPROM emulation require transition from HSRUN to RUN mode (80 MHz) to avoid error flag generation. Memory subsystem features ECC on flash, SRAM, and FlexNVM, plus 4 KB code cache and QuadSPI with HyperBus™ timing compliance.

FAQ

What is the maximum operating frequency of the MWCT1015SFVLLPR and under what conditions?

The MWCT1015SFVLLPR achieves a maximum core frequency of 112 MHz in HSRUN mode, enabled by its System Phase-Locked Loop (SPLL) with a 4–40 MHz external oscillator input. This frequency is validated across -40 °C to +105 °C ambient temperature. Operation above 80 MHz requires HSRUN mode; for CSEc cryptographic operations or EEPROM emulation, the device must drop to RUN mode (80 MHz) to avoid error flag generation - a hardware-enforced restriction documented in the MWCT101xS Data Sheet Rev. 5.

Does the MWCT1015SFVLLPR support CAN-FD, and how is it implemented?

Yes, the MWCT1015SFVLLPR supports CAN-FD through its three FlexCAN modules, with CAN-FD capability explicitly listed in the Feature Comparison table of the MWCT101xS Data Sheet Rev. 5. Each FlexCAN module supports bit rates up to 5 Mbps in FD mode, configurable via register-level settings. The implementation includes hardware CRC, flexible data-length control, and seamless transition between Classical CAN and CAN-FD frames - essential for ISO 15118-2 vehicle-to-charger communication stacks.

How does the CSEc (Cryptographic Services Engine) function in the MWCT1015SFVLLPR?

The CSEc in the MWCT1015SFVLLPR implements the Secure Hardware Extension (SHE) Functional Specification, providing hardware-accelerated AES-128/256 encryption/decryption, SHA-256 hashing, true random number generation, and secure key vaulting. It operates independently of the Cortex-M4F core and is accessed via dedicated APB registers. Critically, CSEc execution is prohibited in HSRUN mode (112 MHz); the MWCT1015SFVLLPR must transition to RUN mode (80 MHz) before initiating any CSEc command - a mandatory safety constraint enforced by the PMC.

What package type and pin count does the MWCT1015SFVLLPR use?

The MWCT1015SFVLLPR uses a 100-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm pitch, as confirmed in the "I/O and package" section of the MWCT101xS Data Sheet Rev. 5 and the ordering information diagram. This package supports full peripheral access - including all three FlexCAN interfaces, dual 12-bit ADCs with 32-channel inputs each, QuadSPI HyperBus™ signals, and 89 GPIOs - while meeting automotive thermal and mechanical reliability requirements for under-hood deployment.

Is ECC (Error-Correcting Code) applied to all memory types in the MWCT1015SFVLLPR?

Yes, ECC is applied to program flash memory (2 MB), SRAM (256 KB), and FlexNVM (64 KB data flash) in the MWCT1015SFVLLPR, as specified in the "Memory and memory interfaces" section of the MWCT101xS Data Sheet Rev. 5. ECC implementation provides SEC-DED (Single Error Correction, Double Error Detection) protection, ensuring data integrity for safety-critical charging state machines and cryptographic key storage. FlexRAM (4 KB) and code cache (4 KB) do not feature ECC, per the datasheet's memory architecture description.
