Product details
Overview
SPC5646BF0MLU1R 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 for EEPROM emulation, 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 SPC5646BF0MLU1R datasheet, SPC5646BF0MLU1R pinout, SPC5646BF0MLU1R application, or SPC5646BF0MLU1R equivalent, key selection criteria include dual-core deterministic timing, hardware memory protection (16-region MPU), autonomous low-power wake-up via RTC (1 ms resolution), CSE-based secure boot, and multi-protocol connectivity (6× FlexCAN, 1× FlexRay, 1× FEC).
Technical Context
The SPC5646BF0MLU1R 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.
It integrates a Safety Enhanced Software Watchdog Timer (SWT) with keyed functionality, FMPLL with frequency modulation, and Cross Trigger Unit (CTU) for synchronized ADC conversions triggered by eMIOS or PIT timers-enabling precise sensor sampling in real-time control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Cores | e200z4d (120 MHz) + e200z0h (80 MHz); enables asymmetric task partitioning with hard real-time guarantees on primary core. |
| Flash Memory | 3 MB code flash with page buffers; reduces instruction fetch latency and supports over-the-air (OTA) update with background erase. |
| SRAM | 256 KB on-chip SRAM; sufficient for AUTOSAR OS stacks, complex control algorithms, and dual-core data exchange buffers. |
| ADC | 1 × 10-bit (27/33 ch) + 1 × 12-bit (5/10 ch); supports simultaneous sampling of engine sensors with CTU-triggered synchronization. |
| Communication | 6 × FlexCAN (64 MB each), 1 × FlexRay (128 MB), 1 × Fast Ethernet (10/100 Mbps); meets domain controller backplane requirements. |
| Security | Cryptographic Services Engine (CSE); accelerates AES-128/256, SHA-256, and RSA-2048 for secure boot and firmware authentication. |
| Power Modes | STOP, HALT, STANDBY; RTC supports autonomous wake-up at 1 ms resolution (max 2 s timeout) for periodic diagnostics without CPU intervention. |
Pinout & Package
SPC5646BF0MLU1R is packaged in a 176-pin LQFP (24 mm × 24 mm, 0.5 mm pitch) with 147 configurable GPIO pins. Power domains include VDD_LV (1.2 V core), VDD_HV_A/B (3.3 V I/O), and dedicated ADC supply rails (VDD_HV_ADC0/ADC1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Asynchronous bidirectional reset input | Schmitt-triggered with internal weak pull-up; initiates full chip reset sequence including PCU, CGM, and RGM modules. |
| XTAL / EXTAL | Crystal oscillator interface | Supports 4–40 MHz external crystal; enables high-accuracy system clock generation with FMPLL multiplication. |
| VDD_LV / VSS_LV | Core power supply / ground | 1.2 V ±5% core domain; requires low-noise regulation for stable e200z4d/e200z0h operation at 120/80 MHz. |
| VDD_HV_A / VSS_HV | I/O power supply / ground | 3.3 V ±10% I/O domain; powers all general-purpose ports, DSPI, LINFlexD, and CAN transceivers. |
| PD[0]–PD[15] | General-purpose port D | 16-bit bidirectional port with programmable slew rate, pull-up/down, and interrupt capability; used for sensor interface and actuator control. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-core deterministic execution | e200z4d handles time-critical control tasks (e.g., fuel injection timing), while e200z0h manages diagnostics, communication stacks, and non-real-time services. |
| Hardware memory protection | 16-region MPU enforces strict isolation between OS, application, and bootloader; required for ISO 26262 ASIL-B/D partitioning. |
| Autonomous peripheral triggering | CTU synchronizes ADC sampling with eMIOS PWM edges-eliminates software jitter in closed-loop motor control. |
| Secure boot acceleration | CSE performs cryptographic verification of boot image in hardware, reducing boot time and preventing unauthorized firmware execution. |
| Low-power wake-up precision | RTC with 1 ms resolution wake-up allows periodic sensor polling during STOP mode without waking CPU-extending battery life in always-on modules. |

How many CAN interfaces does the SPC5646BF0MLU1R provide, and what is their buffer capacity?
The SPC5646BF0MLU1R provides six FlexCAN modules, each with 64 message buffers. These support CAN 2.0B protocol, bit rates up to 1 Mbps, and include a CAN Sampler feature to capture message IDs during low-power modes-enabling selective wake-up without full CAN controller activation.
What low-power modes are supported by the SPC5646BF0MLU1R, and how does RTC wake-up function?
The SPC5646BF0MLU1R supports STOP, HALT, and STANDBY modes. Its Real-Time Counter (RTC) can autonomously wake the device from STOP mode with 1 ms resolution and up to 2 seconds maximum timeout, using internal 128 kHz or 16 MHz oscillators-allowing periodic diagnostics without CPU involvement.
Is the SPC5646BF0MLU1R pin-compatible with other members of the MPC5646C family?
Yes, the SPC5646BF0MLU1R uses the same 176-pin LQFP package (24 mm × 24 mm, 0.5 mm pitch) as MPC5646CK0MLU1R and MPC5646BK0MLU1R, with identical pin assignments and electrical characteristics-enabling drop-in replacement where flash size and CSE presence align with design requirements.
