Product details
Overview
SPC5644BF0VLT1 from NXP Semiconductors is a dual-core automotive microcontroller featuring an e200z4d CPU (up to 120 MHz) and e200z0h CPU (up to 80 MHz), 2 MB on-chip flash, 192 KB SRAM, 64 KB data flash, FlexCAN, DSPI, LINFlexD, and Ethernet MAC. It targets engine control units, transmission controllers, and chassis domain controllers requiring ASIL-B functional safety compliance.
For engineers reviewing the SPC5644BF0VLT1 datasheet, SPC5644BF0VLT1 pinout, SPC5644BF0VLT1 application, or SPC5644BF0VLT1 equivalent, key selection criteria include dual-core deterministic timing, integrated CSE for secure boot, FlexRay + FEC support for high-integrity networking, and validated AEC-Q100 Grade 1 qualification across −40°C to 125°C ambient.
Technical Context
The SPC5644BF0VLT1 implements a crossbar switch architecture enabling concurrent access to flash, SRAM, and peripherals by both e200z4d and e200z0h cores. Its Dual-Core Interrupt Controller routes sources independently to either core or both, supporting asymmetric multiprocessing with shared memory coherency managed via semaphores.
It integrates a Cryptographic Services Engine (CSE) with AES-128/256, SHA-256, and RSA-2048 acceleration, plus a Safety Enhanced Software Watchdog Timer (SWT) with keyed access. The Fast Ethernet Controller complies with IEEE 802.3 10/100 Mbps MII interface and supports time-triggered communication via STM and PIT timers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5646C | 3 MB flash, 256 KB SRAM, 256-ball MAPBGA or 208-pin LQFP; adds FlexRay and FEC not present in SPC5644BF0VLT1 | Targeted at higher-end gateway and ADAS fusion ECUs requiring larger memory and additional high-speed interfaces | Select MPC5646C when >2 MB flash or FlexRay is required; SPC5644BF0VLT1 remains optimal for cost-sensitive engine/transmission ECUs with proven 176-LQFP layout |
| SPC560S50L5 | Single e200z0 core (80 MHz), 1 MB flash, 80 KB SRAM, no Ethernet or FlexRay; 144-pin LQFP | Suitable for non-safety-critical body control modules (BCM) or HVAC controllers with lower performance demands | Choose SPC560S50L5 only for QM-level applications where ASIL-B compliance and dual-core determinism are unnecessary |
Compared with MPC5646C, SPC5644BF0VLT1 offers identical dual-core architecture and peripheral set but reduces flash/SRAM capacity and omits FlexRay to meet cost and thermal constraints in compact engine compartments; versus SPC560S50L5, it delivers certified ASIL-B capability and Ethernet readiness for evolving vehicle network topologies.
