Product details
Overview
SPC5646CCF0MLU1 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 SPC5646CCF0MLU1 datasheet, SPC5646CCF0MLU1 pinout, SPC5646CCF0MLU1 application, or SPC5646CCF0MLU1 equivalent, key selection criteria include dual-core deterministic timing, hardware safety mechanisms (SWT, MPU, ECSM), automotive-grade I/O (177 pins in LQFP), and integrated communication stacks (CAN FD-capable FlexCAN, LINFlexD, FEC).
Technical Context
The SPC5646CCF0MLU1 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 and functional safety partitioning.
It integrates a Safety Enhanced Software Watchdog Timer (SWT), 16-region Memory Protection Unit (MPU), and Error Correction Status Module (ECSM) for memory error detection-core elements of its ISO 26262-compliant safety architecture. The CSE provides AES-128/256, SHA-256, and RSA acceleration for secure boot and firmware updates.
Key Specifications

Pinout & Package
SPC5646CCF0MLU1 is packaged in a 176-pin LQFP (24 mm × 24 mm, 0.5 mm lead pitch) with dedicated power domains (VDD_HV_A, VDD_HV_B, VDD_HV_ADC0/1, VDD_LV), system pins (RESET, EXTAL, XTAL), and 177 configurable GPIOs mapped across ports PA–PK and PI–PL.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Bidirectional reset input with Schmitt-trigger and noise filter | Active-low asynchronous reset with weak internal pull-up; initiates full device reset sequence via MC_RGM module. |
| EXTAL / XTAL | Crystal oscillator inputs (4–40 MHz) | Supports external crystal or ceramic resonator; bypass mode allows direct clock injection into XTAL pin. |
| VDD_HV_A / VDD_HV_B | High-voltage I/O supply domains | VDD_HV_A powers most I/O banks; VDD_HV_B supplies specific high-drive pins (e.g., PA[7–11], PF[14–15]) for flexible voltage domain isolation. |
| VDD_LV | Low-voltage core supply | Supplies e200z4d/e200z0h cores, SRAM, and internal logic; requires tight regulation (±3% at 1.2 V). |
| PE[12]–PF[15] | Configurable GPIO / peripheral multiplexing | Supports alternate functions including DSPI, LINFlexD, CAN, and eMIOS channels; pad type configurable as Slow/Medium/Fast. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-core deterministic execution | e200z4d and e200z0h cores operate at independent frequencies (120 MHz / 80 MHz) with shared crossbar and INTC-enabling lockstep-free safety partitioning. |
| Hardware safety monitoring | Integrated SWT with 32-bit counter and key-based write protection, plus FMPLL clock monitor and CMU for oscillator fault detection. |
| Automotive communication stack | 6 FlexCAN modules support CAN FD frame formats and message filtering; FlexRay controller meets ISO 17458-4 for time-triggered networking. |
| Secure firmware execution | Cryptographic Services Engine (CSE) accelerates AES-128/256 encryption, SHA-256 hashing, and RSA-2048 signing for secure boot and OTA updates. |
| Low-power operation | STOP, HALT, and STANDBY modes with RTC wake-up (1 ms resolution, 2 s max timeout) and autonomous API timer for periodic low-power interrupts. |
