Product details
Overview
SPC5646BCF0VLU1R from NXP Semiconductors is a dual-core automotive microcontroller featuring an e200z4d CPU (up to 120 MHz) and e200z0h CPU (up to 80 MHz), 3 MB on-chip flash, 256 KB SRAM, 64 KB data flash, FlexCAN, FlexRay, Fast Ethernet, and Cryptographic Services Engine (CSE). It targets safety-critical powertrain and chassis control units requiring ASIL-B/D compliance.
For engineers reviewing the SPC5646BCF0VLU1R datasheet, SPC5646BCF0VLU1R pinout, SPC5646BCF0VLU1R application, or SPC5646BCF0VLU1R equivalent, key selection considerations include dual-core deterministic timing, hardware safety mechanisms (SWT, MPU, ECSM), Ethernet/FlexRay coexistence, and automotive-qualified 176-pin LQFP packaging with 0.5 mm pitch.
Technical Context
The SPC5646BCF0VLU1R implements a crossbar switch architecture enabling concurrent access to flash, SRAM, and peripherals by both e200z4d and e200z0h cores. Its Dual-core Interrupt Controller (INTC) routes interrupt sources selectively to either core or both, supporting asymmetric multiprocessing.
It integrates a Cross Trigger Unit (CTU) for precise ADC-timer synchronization, a Safety Enhanced Software Watchdog Timer (SWT) with keyed functionality, and a Boot Assist Module (BAM) executing VLE code at boot. The FMPLL supports programmable frequency modulation for EMI reduction.

Yes, the SPC5646BCF0VLU1R integrates a Fast Ethernet Controller (FEC) supporting both 10 Mbps and 100 Mbps IEEE 802.3 operation. It implements the Media Independent Interface (MII), requiring an external PHY chip for physical layer signaling. The MII interface includes RXD[3:0], TXD[3:0], RX_DV, TX_EN, RX_CLK, TX_CLK, MDIO, and MDC signals routed to dedicated pins on the 176-pin LQFP package.
How many CAN interfaces does the SPC5646BCF0VLU1R include, and what is their buffer capacity?
The SPC5646BCF0VLU1R includes six FlexCAN modules, each with 64 message buffers (MBs), enabling concurrent handling of multiple CAN networks (e.g., powertrain, chassis, body). Each module supports CAN 2.0A/B protocols and features a CAN Sampler for low-power ID capture. Buffer allocation is configurable via software, and all modules are accessible through the crossbar switch for simultaneous DMA transfers.
What safety mechanisms are integrated into the SPC5646BCF0VLU1R for ISO 26262 compliance?
The SPC5646BCF0VLU1R integrates multiple hardware safety mechanisms: a Safety Enhanced Software Watchdog Timer (SWT) with key-based activation, a 16-region Memory Protection Unit (MPU), Error Correction Status Module (ECSM) for ECC reporting, and Nexus3+ debug interface with real-time trace. These features collectively support ASIL-B and ASIL-D system-level decomposition, validated per ISO 26262 Part 5 requirements for microcontroller hardware.
Is the SPC5646BCF0VLU1R pin-compatible with other members of the MPC5646C family?
Yes, the SPC5646BCF0VLU1R in 176-pin LQFP is pin-compatible with other MPC5646C variants sharing the same package (e.g., MPC5646BK0VLU1R, MPC5646CF0VLU1R), as confirmed by identical mechanical drawings and signal mapping in the official datasheet. Pin assignments for RESET, XTAL, power domains, and peripheral I/O match across these variants, enabling drop-in replacement within the same temperature and feature grade constraints.
