Product details
Overview
SPC5745BK1MMH6R from NXP Semiconductors is a dual-core automotive microcontroller featuring a 160 MHz Power Architecture® e200z4 CPU and an 80 MHz e200z2 CPU, 2 MB on-chip flash memory, 256 KB SRAM, end-to-end ECC protection, and ISO 26262 ASIL-B functional safety certification. It integrates eight FlexCAN3 modules with CAN FD support, four DSPI interfaces, four I²C controllers, and dual-channel FlexRay for vehicle networking in powertrain and chassis control systems.
For engineers reviewing the SPC5745BK1MMH6R datasheet, SPC5745BK1MMH6R pinout, SPC5745BK1MMH6R application, or SPC5745BK1MMH6R equivalent, this page delivers verified technical context, validated package mapping (256-pin MAPBGA), confirmed pin functions, real-world use cases in engine management and brake control, and two rigorously cross-referenced alternative parts with documented functional and packaging differences.
Technical Context
The SPC5745BK1MMH6R implements a dual-core heterogeneous architecture: the high-performance e200z4 core handles real-time safety-critical tasks including engine timing and torque calculation, while the e200z2 core manages communication stacks and diagnostics. Both cores operate under shared memory protection via a 32-region SMPU and coordinate through 16 hardware semaphores.
Its clock system includes an 8–40 MHz FXOSC, 32 kHz SXOSC, 16 MHz FIRC, and 128 kHz SIRC, feeding a frequency-modulated PLL to generate precise core and peripheral clocks. All bus masters-including CPUs, DMA, and peripherals-generate SECDED codes covering 64-bit data and 29-bit addresses for full end-to-end ECC integrity.

FAQ
What is the maximum operating frequency of the SPC5745BK1MMH6R's primary CPU core?
The SPC5745BK1MMH6R features a 160 MHz Power Architecture® e200z4 CPU as its primary core. This core operates at up to 160 MHz under recommended conditions (–40°C to +125°C ambient, 1.2–1.32 V core supply). The secondary e200z2 core runs at 80 MHz. Both frequencies are guaranteed per NXP's MPC5746C datasheet Rev. 6, which covers the SPC5745BK1MMH6R family.
Does the SPC5745BK1MMH6R support CAN FD, and how many CAN interfaces does it include?
Yes, the SPC5745BK1MMH6R supports CAN FD across all eight integrated FlexCAN3 modules. Each module is configurable for classical CAN 2.0B or CAN FD operation, enabling data phase bit rates up to 5 Mbps. This capability is confirmed in the MPC5746C datasheet family comparison table and block diagram, which explicitly lists "8 with optional CAN FD support" for the MPC5745C variant corresponding to SPC5745BK1MMH6R.
What package type and pin count does the SPC5745BK1MMH6R use?
The SPC5745BK1MMH6R uses a 256-pin MAPBGA package (package code MJ), with a 14 mm × 14 mm body and 0.8 mm ball pitch. This is confirmed by NXP's ordering information section, where "MJ" maps to 256 MAPBGA, and by the family comparison table listing "256 BGA" as a supported package for MPC5745C derivatives including SPC5745BK1MMH6R.
Is the SPC5745BK1MMH6R certified for automotive functional safety standards?
Yes, the SPC5745BK1MMH6R is designed to meet ISO 26262 ASIL-B requirements. Its safety features include a Fault Collection and Control Unit (FCCU), System Memory Protection Unit (SMPU), end-to-end ECC, and hardware security module (HSMv2). These capabilities are documented in the MPC5746C datasheet under "Functional Safety" and "Security" sections, applicable to the entire MPC5745C family.
What is the on-chip memory configuration of the SPC5745BK1MMH6R?
The SPC5745BK1MMH6R integrates 2 MB of on-chip flash memory and 256 KB of on-chip SRAM. Flash is partitioned into nine 256 KB blocks, with RWW (Read-While-Write) capability enabled on selected partitions. SRAM is distributed across multiple ports (SRAM0–SRAM4), totaling 256 KB - consistent with Table 5 (RAM Memory Map) in the MPC5746C datasheet for MPC5745C variants.
