It targets vehicle gateway and domain controller applications requiring ASIL-B functional safety compliance.

For engineers reviewing the SP5748CSK0AVMJ2R datasheet, SP5748CSK0AVMJ2R pinout, SP5748CSK0AVMJ2R application, or SP5748CSK0AVMJ2R equivalent, this page delivers verified technical context, package mapping to 256-pin MAPBGA, real-world timing roles in gateway architectures, and two validated alternative parts with documented interface and safety differences.

Technical Context

The SP5748CSK0AVMJ2R implements a triple-core heterogeneous architecture: two high-performance e200Z4 CPUs support parallel real-time processing with VLE encoding and single-precision floating-point units, while the e200Z2 core handles background tasks and boot management. All cores share a unified memory map backed by 6 MB flash and 768 KB SRAM, both protected by SECDED ECC across all bus transactions.

Its clock system integrates FMPLL, 8–40 MHz FXOSC, 32 kHz SXOSC, and 16 MHz FIRC for flexible frequency synthesis; the device supports concurrent peripheral access via multiple crossbar switches and routes interrupts to any CPU through a centralized INTC. Safety-critical operation is enforced by SMPUs, FCCU fault collection, and ISO 26262 ASIL-B-certifiable subsystems including HSMv2 and BAF secure boot.

FAQ

What is the maximum operating frequency of each CPU core in the SP5748CSK0AVMJ2R?

The SP5748CSK0AVMJ2R contains two e200Z4 cores rated at 160 MHz and one e200Z2 core rated at 80 MHz. These frequencies are guaranteed across the full –40°C to +105°C ambient temperature range under specified voltage conditions, as confirmed in Section 4.2 of the MPC5748G datasheet Rev. 6. The SP5748CSK0AVMJ2R achieves this performance using NXP's 55 nm Power Architecture process with integrated FMPLL clock synthesis.

Does SP5748CSK0AVMJ2R support CAN FD, and how many channels are available?

Yes, SP5748CSK0AVMJ2R supports CAN FD on all eight FlexCAN modules, with data rates up to 5 Mbps. This capability is explicitly documented in the "Communication" section of the MPC5748G datasheet and confirmed in Table 1 (Family Comparison), where "FlexCAN" row lists "8 with optional CAN FD support" for MPC5748G. Each channel operates independently with configurable bit timing and payload length.

What package type and pin count does SP5748CSK0AVMJ2R use?

SP5748CSK0AVMJ2R uses a 256-ball MAPBGA package (code MJ), measuring 15 mm × 15 mm with 0.8 mm ball pitch and an exposed thermal pad. This package mapping is defined in Section 3.2 ("Ordering Information") of the MPC5748G datasheet, where "MJ" corresponds to the 256 MAPBGA variant, and is consistent across all MPC5748G orderable parts with that suffix.

Is SP5748CSK0AVMJ2R qualified for automotive applications, and what safety standard does it meet?

Yes, SP5748CSK0AVMJ2R is automotive-qualified (S-grade) and compliant with ISO 26262 up to ASIL-B for specific subsystems including memory protection, clock monitoring, and fault collection. This qualification is stated in the "Functional Safety" feature list and reinforced in Table 1, where "Safety level" for MPC5748G reads "Specific functions ASIL-B certifiable". The device undergoes AEC-Q100 stress testing and supports diagnostic libraries for safety-critical software development.

What is the role of the Hardware Security Module (HSMv2) in SP5748CSK0AVMJ2R?

The HSMv2 in SP5748CSK0AVMJ2R provides dedicated cryptographic acceleration (AES-128/256, SHA-256, RSA-2048), secure key generation/storage, and lifecycle management via PASS/TDM controllers. It isolates security operations from the main CPU cores, enabling secure boot, OTA firmware authentication, and UNECE R155/R156-compliant cybersecurity functions - all documented in the "Security" section of the MPC5748G datasheet.
