NXP Semiconductors SPC5644CK0VLU1

Overview

SPC5644CK0VLU1 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 support - deployed in engine control units, transmission controllers, and chassis domain controllers.

For engineers reviewing the SPC5644CK0VLU1 datasheet, SPC5644CK0VLU1 pinout, SPC5644CK0VLU1 application, or SPC5644CK0VLU1 equivalent, key selection criteria include dual-core deterministic timing, ASIL-B functional safety compliance, integrated FEC for vehicle networking, and 208-pin LQFP package with 28 mm × 28 mm footprint and 0.5 mm pitch.

Technical Context

The SPC5644CK0VLU1 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 lockstep or independent operation modes.

It integrates a Fast Ethernet Controller (FEC) compliant with IEEE 802.3 for 10/100 Mbps operation, plus six FlexCAN modules (64 message buffers each), CTU for ADC-timer synchronization, and Cryptographic Services Engine (CSE) for secure boot and runtime encryption - all aligned with ISO 26262 ASIL-B requirements.

Key Specifications

Pinout & Package

SPC5644CK0VLU1 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, XTAL, and VRC_CTRL.

FAQ

What is the maximum operating frequency of the SPC5644CK0VLU1's primary CPU core?

The SPC5644CK0VLU1 features an e200z4d core rated for up to 120 MHz operation under AEC-Q100 Grade 1 conditions (−40°C to +125°C ambient). This frequency is achievable with proper thermal design and stable 3.3 V supply; the e200z0h secondary core operates up to 80 MHz, or at half-system frequency when the e200z4d runs above 80 MHz. The SPC5644CK0VLU1 datasheet specifies timing margins and voltage dependencies for both cores.

Does the SPC5644CK0VLU1 support Ethernet communication, and what interface standard does it implement?

Yes, the SPC5644CK0VLU1 integrates a Fast Ethernet Controller (FEC) compliant with IEEE 802.3 for 10/100 Mbps operation. It implements the Media Independent Interface (MII) with dedicated RXD[3:0], TXD[3:0], RX_DV, TX_EN, RX_CLK, TX_CLK, and MDC/MDIO signals. The FEC supports full-duplex mode, store-and-forward buffering, and hardware checksum offload - essential for diagnostic-over-IP and firmware update applications in modern vehicle networks.

What safety certifications and hardware features does the SPC5644CK0VLU1 provide for ASIL-B compliance?

The SPC5644CK0VLU1 includes MPU (16-region), keyed Software Watchdog Timer (SWT), Crossbar switch with error detection, STCU-controlled MBIST, and CSE for cryptographic integrity - all documented in NXP's ISO 26262 ASIL-B ready documentation package. It supports lockstep operation between cores for fault detection and provides hardware-assisted memory protection and clock monitoring. These features form the foundation for ASIL-B system-level certification when integrated per NXP's safety manual and FMEDA reports.

How many CAN interfaces does the SPC5644CK0VLU1 integrate, and what is their buffer capacity?

The SPC5644CK0VLU1 integrates six FlexCAN modules, each with 64 message buffers (MBs), supporting standard and extended CAN identifiers, bit rates up to 1 Mbps, and low-power CAN Sampler functionality. This configuration enables concurrent handling of powertrain, chassis, and body CAN networks without external CAN controllers. The SPC5644CK0VLU1 also supports CAN FD in later revisions of the MPC5646C family, but this specific variant implements classical CAN only per its datasheet revision 7.

What package type and pin count does the SPC5644CK0VLU1 use, and are there compatible footprints?

The SPC5644CK0VLU1 uses a 208-pin LQFP package with 28 mm × 28 mm body size and 0.5 mm lead pitch. It shares mechanical and thermal characteristics with other MPC564x family members in the same package variant, including identical land pattern, solder mask, and reflow profile requirements. Pin-compatible migration paths exist to MPC5646C in 256-ball MAPBGA, but PCB redesign is required due to differing package geometry and ball/pin mapping.
