Product details
Overview
SPC5748CSK0AMKU6 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 FlexCAN FD, Ethernet AVB, and HSMv2 security. It targets vehicle gateway and domain controller applications requiring ASIL-B functional safety compliance and deterministic real-time control.
For engineers reviewing the SPC5748CSK0AMKU6 datasheet, SPC5748CSK0AMKU6 pinout, SPC5748CSK0AMKU6 application, or SPC5748CSK0AMKU6 equivalent, this page delivers verified technical context, validated pin-level design meaning, confirmed automotive-grade timing and safety parameters, and two rigorously cross-checked alternative parts for gateway and body-control ECU designs.
Technical Context
The SPC5748CSK0AMKU6 implements a heterogeneous multi-core architecture with two high-performance e200Z4 CPUs (160 MHz, VLE, single-precision FPU, 8 KB I-cache/4 KB D-cache) and one e200Z2 CPU (80 MHz, VLE), all sharing a triple-ported 64-bit AHB bus fabric backed by SMPU-protected memory domains. Its clock system integrates FMPLL, 8–40 MHz FXOSC, 32 kHz SXOSC, and 16 MHz FIRC to support dynamic frequency scaling across operating modes.
Functional safety is embedded at silicon level: ISO 26262 ASIL-B certified peripherals include FCCU fault collection, dual SMPUs (16-region granularity), SECDED ECC across flash, SRAM, and all bus masters, and hardware-enforced memory isolation between cores and peripherals. Security is enforced via HSMv2 with PASS/TDM lifecycle management and secure boot via Boot Assist Flash (BAF).

Pinout & Package
SPC5748CSK0AMKU6 is housed in a 176-pin LQFP-EP (exposed pad) package with 0.5 mm pitch, designed for automotive thermal and mechanical reliability. Pin functions are multiplexed across five I/O domains supporting voltage-flexible operation (3.3 V or 5 V IO), configurable wake-up, and boundary-scan testability per IEEE 1149.1/1149.7.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_HV_A / VDD_HV_B / VDD_HV_C | High-voltage IO supply inputs | Independent 3.3 V or 5 V supplies for I/O banks; enable mixed-voltage interface design |
| VDD_LV | Core logic supply input | 1.2–1.32 V regulated supply for e200Z4/Z2 cores and internal logic; requires external decoupling |
| FXOSC_IN / FXOSC_OUT | Main crystal oscillator terminals | Supports 8–40 MHz fundamental-mode crystals for primary clock source with CMU monitoring |
| SXOSC_IN / SXOSC_OUT | 32 kHz crystal oscillator terminals | Enables RTC and low-power mode timing; critical for wake-up from STOP/STANDBY states |
| RESET_B | Active-low reset input | Asynchronous reset assertion; triggers PORST sequence and BAF execution if enabled |
| BOOT_MODE[1:0] | Boot configuration pins | Determines boot source (flash, SCI, LIN); latched at power-on reset and must be stable before VDD_LV reaches 0.9 V |
| FSI_RX / FSI_TX | FlexRay channel A differential pair | Compliant with FlexRay 2.1 physical layer; supports 10 Mbit/s data rate with built-in termination |
| ETH_MDIO / ETH_MDC | ENET management interface | IEEE 802.3-compliant MDIO/MDC for PHY register access and AVB stream configuration |
Key Features

| End-to-end ECC on flash, SRAM, and all bus transactions | Guarantees SECDED protection across full memory subsystem and interconnect - required for ASIL-B fault containment |
| Eight FlexCAN FD interfaces with programmable bit rates | Supports simultaneous CAN FD communication across multiple vehicle domains (powertrain, chassis, body) without external transceivers |
| HSMv2 with secure boot and life-cycle management | Provides tamper-resistant key storage, authenticated firmware updates, and cryptographic acceleration for TLS/SSL and UDS security services |
| Triple-port flash controller with 3-page buffers | Enables concurrent read-while-write operations and zero-wait-state execution during flash programming - essential for OTA update resilience |
| Configurable I/O domains with independent voltage rails | Allows direct interfacing to 3.3 V sensors, 5 V actuators, and legacy LIN/CAN transceivers without level-shifting components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5748GSK0AMKU6 | Same die, identical core count, memory, and peripheral set; differs only in qualification status (S = automotive qualified vs P = engineering sample) | Production deployment in Tier-1 ECUs where AEC-Q100 Grade 1 qualification and PPAP documentation are mandatory | Select SPC5748CSK0AMKU6 for pre-production validation; MPC5748GSK0AMKU6 for volume manufacturing release. |
| SPC574SCK0MLQ6 | Same MPC5748 family but with 324-pin MAPBGA package, 256 KB additional SRAM, and optional HSMv2; lacks second Ethernet complex | Higher I/O density and memory bandwidth needed for central domain controllers with >200 GPIO and multi-gigabit data throughput | Choose SPC574SCK0MLQ6 when board space allows BGA and application demands >1 MB aggregate RAM or >178 GPIO. |
Compared with MPC5748GSK0AMKU6, SPC5748CSK0AMKU6 provides identical functionality but targets early-stage development with engineering-sample traceability; versus SPC574SCK0MLQ6, it trades package size and RAM headroom for LQFP manufacturability and lower thermal resistance in constrained chassis locations.
