FAQ
What is the maximum ambient operating temperature for SPC5742PK1MLQ5R?
The SPC5742PK1MLQ5R is qualified per AEC-Q100 Grade 1 with an ambient operating temperature range of −40°C to 125°C. This rating is validated across all electrical parameters and safety mechanisms, including lockstep core comparison, ECC memory scrubbing, and FCCU fault reporting - ensuring reliable operation in under-hood environments where thermal stress is critical. The SPC5742PK1MLQ5R maintains full ASIL-D compliance throughout this range.
Does SPC5742PK1MLQ5R support CAN FD or only classical CAN?
The SPC5742PK1MLQ5R integrates three FlexCAN modules that support ISO 11898-1:2015, including CAN FD frame format with flexible data-rate up to 5 Mbit/s. Each module features message RAM with hardware filtering, time stamping, and loopback mode for validation. The SPC5742PK1MLQ5R uses these interfaces for high-bandwidth communication with radar ECUs and ADAS domain controllers - essential for adaptive cruise control and automated emergency braking systems.
How is functional safety implemented in SPC5742PK1MLQ5R for ISO 26262 ASIL-D compliance?
The SPC5742PK1MLQ5R achieves ISO 26262 ASIL-D compliance through hardware-enforced dual-core lockstep execution, end-to-end ECC on flash and SRAM, duplicate safety-critical peripherals, built-in LBIST/MBIST, ADC self-test, and centralized Fault Collection and Control Unit (FCCU). These mechanisms are fully documented in NXP's safety manual for MPC574xP. The SPC5742PK1MLQ5R implements all required safety goals without external components.
What package type and pin count does SPC5742PK1MLQ5R use?
The SPC5742PK1MLQ5R uses a 144-pin LQFP package (16 mm × 16 mm, 0.5 mm pitch) with exposed thermal pad. It shares mechanical and pin-compatible footprint with other MPC574xP variants including SPC5744P and SPC5743P. Pin assignments support dual FlexRay, triple FlexCAN, four SENT inputs, and six FlexPWM outputs - all accessible without ball-grid array complexity. The SPC5742PK1MLQ5R does not offer BGA variant in this specific orderable part number.
Can SPC5742PK1MLQ5R be used in Ethernet-enabled automotive applications?
No, the SPC5742PK1MLQ5R does not integrate an Ethernet MAC or PHY. While the MPC574xP family block diagram shows Ethernet as an optional feature, it is only implemented in higher-tier variants such as SPC5777M. The SPC5742PK1MLQ5R relies on FlexRay, FlexCAN, and LINFlexD for deterministic in-vehicle networking. For Ethernet-dependent applications like zonal gateways, designers must select alternate NXP families such as S32K3 or S32G.
