NXP Semiconductors SPC5747CK1VMJ6R

Overview

SPC5747CK1VMJ6R from NXP Semiconductors is an automotive-qualified Power Architecture® microcontroller featuring dual e200z4 cores (160 MHz) and one e200z2 core (80 MHz), 4 MB on-chip flash, 512 KB SRAM, end-to-end ECC, and integrated FlexCAN3 with FD support. It targets vehicle gateway and body control modules requiring ASIL-B functional safety compliance, real-time deterministic execution, and multi-protocol communication.

For engineers reviewing the SPC5747CK1VMJ6R datasheet, SPC5747CK1VMJ6R pinout, SPC5747CK1VMJ6R application, or SPC5747CK1VMJ6R equivalent, this device delivers verified CAN FD, Ethernet (RMII/MII), LINFlexD, DSPI/SPI, USB OTG/SPH, and hardware security (HSMv2) in a 256-pin MAPBGA package - critical for automotive ECU design, powertrain interface, and domain controller architecture validation.

Technical Context

The SPC5747CK1VMJ6R implements a triple-core heterogeneous architecture: two high-performance e200z4 CPUs (160 MHz, VLE, single-precision FPU, 8 KB I-cache/4 KB D-cache) plus one e200z2 CPU (80 MHz, VLE) for dedicated safety monitor or peripheral management. All cores operate with full end-to-end ECC protection across buses, flash, and SRAM, covering 64-bit data and 29-bit addresses.

Its memory subsystem includes 4 MB flash (with 3-port controller and Boot Assist Flash), 512 KB SRAM distributed across three ports, and configurable SMPU_0 (12-region) and SMPU_1 (12-region) for memory access enforcement. Clocking supports FXOSC (8–40 MHz), SXOSC (32 kHz), FIRC (16 MHz), SIRC (128 kHz), FMPLL, and RTC/API - enabling precise timing for CAN FD bit-rate synchronization and Ethernet AVB timestamping.

FAQ

What is the maximum operating frequency of the SPC5747CK1VMJ6R's CPU cores?

The SPC5747CK1VMJ6R features two e200z4 cores operating at up to 160 MHz and one e200z2 core at up to 80 MHz. These frequencies are guaranteed under automotive conditions (−40°C to +125°C ambient) with appropriate voltage regulation and cooling. The SPC5747CK1VMJ6R does not support overclocking beyond these rated speeds, and all timing-critical peripherals (e.g., FlexCAN FD, Ethernet) are validated only at these specified core frequencies.

Does the SPC5747CK1VMJ6R support CAN FD, and how many channels are available?

Yes, the SPC5747CK1VMJ6R supports CAN FD on all eight FlexCAN3 modules. Each channel operates at data rates up to 5 Mbps in FD mode and maintains full backward compatibility with classical CAN 2.0B. This capability is confirmed in the MPC5748G family datasheet Table 1, where SPC5747C (the base part for SPC5747CK1VMJ6R) lists "8 with optional CAN FD support" - and the 'K' suffix in the orderable part number indicates CAN FD is enabled.

What package type and pin count does the SPC5747CK1VMJ6R use?

The SPC5747CK1VMJ6R uses a 256-ball MAPBGA package (package code MJ), with 0.8 mm ball pitch and a 15 mm × 15 mm body size. This package is explicitly defined in NXP's ordering information guide (Section 3.2), where 'MJ' maps to the 256 MAPBGA variant. It is distinct from the 176 LQFP-EP (KU) and 324 MAPBGA (MN) options in the same family.

Is the SPC5747CK1VMJ6R qualified for automotive applications, and what temperature grade does it support?

Yes, the SPC5747CK1VMJ6R is automotive-qualified per AEC-Q100 Grade 1, supporting operation from −40°C to +125°C ambient temperature. The 'V' in the part number denotes the 125°C rating, and the 'S' qualification status (embedded in the family definition) confirms full automotive qualification - including HTOL, TC, and ESD testing. This makes the SPC5747CK1VMJ6R suitable for under-hood and transmission-control applications.

Does the SPC5747CK1VMJ6R include hardware security features, and which ones are implemented?

No, the SPC5747CK1VMJ6R does not include the Hardware Security Module (HSM). Unlike the 'S' or 'B' variants (e.g., SPC5747SK1VMJ6R), the base SPC5747C derivative lacks HSMv2. However, it retains foundational security elements: password-based device security (PASS), tamper detection (TDM), secure boot ROM, and cryptographic acceleration via the CSEc module - sufficient for basic secure boot and firmware authentication but not for advanced OTA key management or AES-GCM offload.
