Product details
Overview
SPC5646CCF0VLU1 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, FlexCAN, FlexRay, Fast Ethernet, and Cryptographic Services Engine (CSE). It targets safety-critical powertrain and chassis control systems requiring ASIL-B compliance and real-time deterministic execution.
For engineers reviewing the SPC5646CCF0VLU1 datasheet, SPC5646CCF0VLU1 pinout, SPC5646CCF0VLU1 application, or SPC5646CCF0VLU1 equivalent, key selection criteria include dual-core interrupt routing via Dual-core INTC, 6 FlexCAN modules with CAN Sampler for low-power message ID capture, 12-bit + 10-bit ADCs with CTU synchronization, and hardware-based CSE for secure boot and firmware authentication.
Technical Context
The SPC5646CCF0VLU1 implements a crossbar switch architecture enabling concurrent access to flash, SRAM, and peripherals by both e200z4d and e200z0h cores. Its Dual-core INTC supports independent or shared interrupt routing, while the Cross Trigger Unit (CTU) synchronizes ADC conversions with eMIOS timer events or PIT outputs for precise sensor sampling in motor control loops.
It integrates a Safety Enhanced Software Watchdog Timer (SWT) with keyed functionality, FMPLL for programmable frequency modulation, and voltage regulator (VREG) with dedicated ADC supply domains (VDD_HV_ADC0/ADC1). The device supports autonomous wake-up from STOP mode via RTC with 1 ms resolution (internal 128 kHz oscillator) or 1 s resolution (external 32 kHz crystal).
Key Specifications

Pinout & Package
SPC5646CCF0VLU1 is packaged in a 208-pin LQFP (28 mm × 28 mm, 0.5 mm lead pitch) with dedicated power domains: VDD_HV_A (core/peripheral I/O), VDD_HV_B (selected port I/O), VDD_HV_ADC0/ADC1 (analog supplies), and VDD_LV (low-voltage logic). Pin functions are multiplexed across SIUL-controlled ports (PA–PK, PL, PM) with configurable pad types (Slow/Medium/Fast, Analog/Input-only).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Bidirectional reset input with Schmitt-trigger and noise filter | Enables robust reset assertion under automotive electrical transients; weak internal pull-up ensures defined state during power ramp. |
| XTAL / EXTAL | Differential crystal oscillator inputs | Supports 4–40 MHz external crystal; bypass mode allows use of external clock source for timing flexibility in ECU designs. |
| VDD_HV_A / VSS_HV | Main I/O power supply and ground | Supplies all general-purpose I/O ports except those assigned to VDD_HV_B; requires local decoupling per JEDEC guidelines. |
| VDD_HV_ADC0 / VSS_HV_ADC0 | Analog domain supply for 10-bit ADC | Isolated analog rail minimizes digital switching noise coupling into precision ADC measurements. |
| PE[12]–PF[15] | GPIO with VDD_HV_B supply | Assigned to secondary I/O domain; enables independent voltage scaling for specific peripheral interfaces (e.g., LINFlexD or DSPI). |
Key Features
| Feature | Design Value |
|---|---|
