NXP Semiconductors SPC5644CF0VLU8

Overview

SPC5644CF0VLU8 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 SPC5644CF0VLU8 datasheet, SPC5644CF0VLU8 pinout, SPC5644CF0VLU8 application, or SPC5644CF0VLU8 equivalent, key selection criteria include dual-core deterministic timing, integrated CSE cryptographic engine, 6 FlexCAN modules with CAN Sampler, 10 LINFlexD interfaces, and 177-pin LQFP package with 3.3 V I/O voltage domain support.

Technical Context

The SPC5644CF0VLU8 implements a crossbar switch architecture enabling concurrent access to flash, SRAM, and peripherals by multiple bus masters-including 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 Fast Ethernet Controller (FEC) compliant with IEEE 802.3 for 10/100 Mbps operation, a Cryptographic Services Engine (CSE) for AES-128/256 and SHA-256 acceleration, and a Cross Trigger Unit (CTU) synchronizing ADC conversions with eMIOS timer events-enabling precise sensor sampling in real-time powertrain applications.

FAQ

What is the maximum operating frequency of the SPC5644CF0VLU8 dual-core architecture?

The SPC5644CF0VLU8 features two independent Power Architecture cores: the e200z4d runs at up to 120 MHz for high-performance real-time tasks, while the e200z0h operates at up to 80 MHz for auxiliary or safety-monitoring functions. When the e200z4d runs above 80 MHz, the e200z0h clock is automatically divided to maintain synchronization-ensuring deterministic timing across both cores in the SPC5644CF0VLU8.

Does the SPC5644CF0VLU8 support AUTOSAR-compliant software stacks?

Yes, the SPC5644CF0VLU8 is fully supported by AUTOSAR 4.x-compliant MCAL drivers from NXP and third-party vendors. Its dual-core architecture, 16-region MPU, SWT watchdog, and Nexus3+ debug interface meet AUTOSAR OS requirements for memory protection, timing predictability, and error handling-enabling seamless integration of SPC5644CF0VLU8 into production-grade AUTOSAR-based ECU software.

What package type and pin count does the SPC5644CF0VLU8 use?

The SPC5644CF0VLU8 uses a 176-pin LQFP package measuring 24 mm × 24 mm with 0.5 mm lead pitch. This package is defined in NXP's MPC5646C datasheet Rev. 7, Figure 2, and supports standard automotive PCB assembly processes including lead-free reflow. The pinout includes dedicated domains for core (1.2 V), I/O (3.3 V), and analog (3.3 V) supplies-critical for noise-sensitive powertrain applications using the SPC5644CF0VLU8.

How does the CAN Sampler feature function in low-power modes on the SPC5644CF0VLU8?

The CAN Sampler in the SPC5644CF0VLU8 captures incoming CAN message identifiers while the device is in STOP mode-without waking the CPU cores. It stores up to 8 message IDs in dedicated registers, allowing selective wake-up only when relevant messages (e.g., ignition-on request) are detected. This reduces average current consumption and extends battery life in always-on vehicle networks, a key capability confirmed in the SPC5644CF0VLU8's FlexCAN module specification.

Is the Cryptographic Services Engine (CSE) on the SPC5644CF0VLU8 enabled by default?

No, the CSE on the SPC5644CF0VLU8 is optional and must be explicitly enabled via the CSE_CTRL register after power-on reset. Once activated, it supports AES-128/256 encryption/decryption, SHA-256 hashing, and true random number generation-all in hardware with zero CPU cycle overhead. Its presence is verified in the SPC5644CF0VLU8's silicon revision and documented in the MPC5646C Reference Manual Chapter 22.
