Product details
Overview
SPC5644BF0VLU1 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, LINFlexD, DSPI, Ethernet (FEC), and cryptographic services (CSE). It targets engine control units and advanced driver assistance systems requiring functional safety and real-time determinism.
For engineers reviewing the SPC5644BF0VLU1 datasheet, SPC5644BF0VLU1 pinout, SPC5644BF0VLU1 application, or SPC5644BF0VLU1 equivalent, key selection criteria include dual-core timing isolation, ASIL-B capable peripheral sets, 177 GPIO count in 208-pin LQFP, and integrated CSE for secure boot and firmware authentication.
Technical Context
The SPC5644BF0VLU1 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 independently to either core or both, supporting asymmetric multiprocessing with hardware-enforced memory protection via a 16-entry MPU.
It integrates a Fast Ethernet Controller (FEC) compliant with IEEE 802.3 for 10/100 Mbps operation, a Safety Enhanced Software Watchdog Timer (SWT) with keyed functionality, and a Cross Trigger Unit (CTU) synchronizing ADC conversions with eMIOS or PIT timer events-enabling precise sensor sampling in closed-loop control.

Pinout & Package
SPC5644BF0VLU1 is housed in a 208-pin LQFP package (28 mm × 28 mm, 0.5 mm lead pitch), with dedicated power domains (VDD_HV_A, VDD_HV_B, VDD_LV), analog supply rails (VDD_HV_ADC0/ADC1), and system pins including RESET, EXTAL, and XTAL. Pin functions are multiplexed across SIUL-controlled GPIO ports (PA–PK, PL, PM) and peripheral-specific signals (e.g., CAN0_TX/RX, FEC_MDC/MDIO).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

FAQ
What is the maximum operating frequency of the primary CPU core in the SPC5644BF0VLU1?
The primary CPU core in the SPC5644BF0VLU1 is the e200z4d, which operates at up to 120 MHz. This frequency is achievable under AEC-Q100 Grade 1 conditions (−40°C to +125°C ambient) and is supported by the FMPLL clock generation module. The SPC5644BF0VLU1's timing specification is fully characterized at this speed, enabling deterministic execution of real-time control algorithms.
Does the SPC5644BF0VLU1 support AUTOSAR-compliant software stacks?
Yes, the SPC5644BF0VLU1 supports AUTOSAR 4.x-compliant software stacks through NXP's SPC5 Studio IDE and MCAL drivers. Its dual-core architecture, memory protection unit (MPU), and standardized peripheral registers align with AUTOSAR BSW requirements. The SPC5644BF0VLU1 has been validated with leading AUTOSAR toolchains for ECU abstraction, RTE, and OS layer integration.
What safety certifications does the SPC5644BF0VLU1 hold?
The SPC5644BF0VLU1 is qualified to AEC-Q100 Grade 1 (−40°C to +125°C) and includes hardware features supporting ISO 26262 ASIL-B compliance-including a Safety Enhanced SWT, 16-entry MPU, ECC on flash/SRAM, and STCU-controlled MBIST. While certification is system-level, the SPC5644BF0VLU1 provides the foundational hardware safety mechanisms required for ASIL-B decomposition.
How many CAN interfaces does the SPC5644BF0VLU1 integrate, and what protocol versions are supported?
The SPC5644BF0VLU1 integrates six FlexCAN modules, each supporting CAN 2.0A/B protocols with 64 message buffers per module. All six controllers support bit rates up to 1 Mbps and include CAN Sampler functionality for low-power message ID capture. They are fully compatible with AUTOSAR CAN Driver and CAN Interface modules.
Is the SPC5644BF0VLU1 pin-compatible with other members of the SPC56xx family?
No, the SPC5644BF0VLU1 is not universally pin-compatible across the SPC56xx family. It uses a 208-pin LQFP package, while variants like SPC5645C use 256-ball MAPBGA. Even within LQFP, pinouts differ between SPC5644B and SPC5645B due to peripheral allocation changes. Board design must be verified against the specific SPC5644BF0VLU1 pinout diagram in the official datasheet.
