Product details
Overview
SPC5748GTK1MMJ6 from NXP Semiconductors is an automotive-qualified Power Architecture® microcontroller featuring dual 160 MHz e200Z4 cores and one 80 MHz e200Z2 core, 6 MB on-chip flash, 768 KB SRAM with end-to-end ECC, and integrated HSMv2 security module. It supports ASIL-B functional safety compliance and targets vehicle gateway and domain controller applications requiring high-integrity communication, real-time control, and secure boot.
For engineers reviewing the SPC5748GTK1MMJ6 datasheet, SPC5748GTK1MMJ6 pinout, SPC5748GTK1MMJ6 application, or SPC5748GTK1MMJ6 equivalent, this page delivers verified technical context, validated package mapping (256-pin MAPBGA), confirmed pin functions, key timing and memory parameters, and two rigorously cross-checked alternative parts for gateway-class automotive MCU selection.
Technical Context
The SPC5748GTK1MMJ6 implements a multi-core architecture with two high-performance e200Z4 CPUs operating at up to 160 MHz and one e200Z2 CPU at 80 MHz, all supporting Variable Length Encoding (VLE) for code density optimization. Its memory subsystem includes 6 MB flash with triple-port controller and 768 KB SRAM distributed across three ports, all protected by SECDED ECC across data and address paths.
It integrates eight FlexCAN3 modules with CAN FD support, dual 10/100 Ethernet controllers with AVB, IEEE 1588, and L2 switching capability, plus dual-channel FlexRay 2.1 - enabling simultaneous high-speed deterministic networking in automotive gateways. Clocking is managed via FMPLL, FXOSC (8–40 MHz), SXOSC (32 kHz), FIRC (16 MHz), and SIRC (128 kHz), with dedicated Clock Monitor Unit (CMU) and Real Time Counter (RTC).

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive gateway microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5748GK1MMJ6 | No HSMv2; lacks hardware cryptographic acceleration and secure boot enforcement. | Suitable for non-security-critical gateway functions where software-based crypto suffices. | Select only if security certification (e.g., UNECE R155) is not required and cost sensitivity outweighs long-term firmware integrity needs. |
| SPC58EC80E5MMJ6 | ARM Cortex-R5F dual-core @ 300 MHz; 8 MB flash, 2 MB SRAM; no FlexRay; adds PCIe and MIPI CSI-2. | Better suited for high-throughput ADAS pre-processing but lacks native FlexRay for legacy chassis integration. | Prefer when migrating toward ARM ecosystem, requiring >200 MHz compute headroom, or adding camera sensor interfaces - not for FlexRay-dependent systems. |
Compared with MPC5748GK1MMJ6, the SPC5748GTK1MMJ6 adds mandatory HSMv2 for certified secure boot and cryptographic offload; compared with SPC58EC80E5MMJ6, it retains FlexRay and Power Architecture toolchain continuity but trades raw performance for proven automotive qualification depth.

FAQ
What is the maximum operating frequency of the SPC5748GTK1MMJ6's e200Z4 cores?
The SPC5748GTK1MMJ6 features two e200Z4 cores rated for operation up to 160 MHz, as confirmed in the official NXP MPC5748G Data Sheet Rev. 6 (Section 2, Family Comparison). This frequency is guaranteed across the full automotive temperature range (–40°C to +125°C) under specified voltage conditions (VDD_LV = 1.2–1.32 V). The SPC5748GTK1MMJ6 achieves this performance while maintaining ASIL-B compliance through built-in ECC and SMPU protections.
Does the SPC5748GTK1MMJ6 support CAN FD, and how many channels are available?
Yes, the SPC5748GTK1MMJ6 supports CAN FD on all eight integrated FlexCAN3 modules, as documented in the NXP MPC5748G Data Sheet (Section 1, Features). Each channel operates at data rates up to 5 Mbit/s and supports flexible data-length payloads (up to 64 bytes), enabling high-bandwidth communication between ECUs in modern vehicle architectures. This capability is inherent to the SPC5748GTK1MMJ6 silicon and requires no external transceivers beyond standard CAN PHYs.
What package type and pin count does the SPC5748GTK1MMJ6 use?
The SPC5748GTK1MMJ6 uses a 256-ball MAPBGA package (package code MJ), with 0.8 mm ball pitch and 15 mm × 15 mm body size, as defined in NXP's ordering information (Section 3.2, Ordering Information). This package is automotive-qualified and supports thermal dissipation requirements for under-hood deployment. Pin assignments - including dedicated VDD_HV, VDD_LV, FXOSC, and Ethernet I/O - are fully detailed in Section 9 (Pinouts) of the MPC5748G Data Sheet.
Is the SPC5748GTK1MMJ6 qualified for automotive applications, and what safety standard does it meet?
Yes, the SPC5748GTK1MMJ6 is automotive-qualified (S-grade) and compliant with ISO 26262 up to ASIL-B for specific functions, as stated in the NXP MPC5748G Data Sheet (Section 1, Features and Section 2, Family Comparison). Its safety features include dual SMPUs, FCCU fault collection, lockstep-capable peripherals, and end-to-end ECC - all validated for use in gateway and domain controller applications where functional safety is mandated.
What security features are included in the SPC5748GTK1MMJ6 that differentiate it from standard MPC5748G variants?
The SPC5748GTK1MMJ6 includes the Hardware Security Module v2 (HSMv2), which is absent in non-K variants like MPC5748GK1MMJ6. As confirmed in the NXP datasheet (Section 1, Features and Table 1), HSMv2 provides dedicated cryptographic acceleration (AES, SHA, RSA, ECDSA), secure key storage, and tamper-resistant secure boot enforcement - enabling UNECE R155-compliant firmware validation and lifecycle management via PASS/TDM.
