Product details
Overview
SPC5644AF0MLU2 from NXP Semiconductors (formerly Freescale) is a 32-bit Power Architecture® microcontroller with a 150 MHz e200z4 core, 4 MB on-chip flash with ECC, 192 KB SRAM with ECC, and integrated FlexRay, FlexCAN, eTPU2, and eQADC for automotive powertrain and chassis control. It supports real-time deterministic execution in engine management systems.
For engineers reviewing the SPC5644AF0MLU2 datasheet, SPC5644AF0MLU2 pinout, SPC5644AF0MLU2 application, or SPC5644AF0MLU2 equivalent, key selection criteria include its 150 MHz e200z4 core with VLE and SPE extensions, dual-channel 12-bit eQADC with 688 ns conversion time, 32-channel eTPU2 for precise timing-critical actuator control, FlexRay v2.1 compliance at up to 10 Mbit/s, and 16-entry MPU for ASIL-B–capable memory protection.
Technical Context
The SPC5644AF0MLU2 implements a superscalar e200z4 core with two execution units, supporting up to two integer or floating-point instructions per cycle and four MAC operations per cycle. Its architecture includes a 5×4 crossbar switch enabling concurrent access by CPU, eDMA, FlexRay, and EBI to flash, SRAM, and peripheral bridge resources.
Real-time subsystems are tightly coupled: the eTPU2 provides 32 independent timing channels with reaction module support for safety-critical PWM generation; the eQADC features six command queues, trigger/DMA synchronization, and expandable input count via external multiplexers; and the FMPLL delivers programmable frequency modulation (0–2% depth, up to 100 kHz) for EMI reduction in automotive environments.

FAQ
What is the maximum operating frequency of the SPC5644AF0MLU2 core?
The SPC5644AF0MLU2 features a 150 MHz e200z4 Power Architecture® core. This maximum frequency is achievable under specified voltage (5 V main supply) and temperature (−40°C to +125°C) conditions per AEC-Q100 Grade 1 qualification. The FMPLL supports dynamic frequency scaling, but 150 MHz represents the highest sustained clock rate validated for full peripheral operation in the SPC5644AF0MLU2 device.
Does the SPC5644AF0MLU2 support FlexRay communication?
Yes, the SPC5644AF0MLU2 integrates a fully compliant FlexRay v2.1 module supporting up to 10 Mbit/s, dual or single channel operation, 128 message objects, and ECC protection for message RAM. It meets ISO 17458-4 requirements and is used in time-triggered automotive networks such as X-by-Wire systems. The FlexRay interface is accessible via dedicated LVDS-capable pins FRAY_TXA/FRAY_RXA and FRAY_TXB/FRAY_RXB on the 208 MAPBGA package.
What type of memory protection does the SPC5644AF0MLU2 provide for functional safety?
The SPC5644AF0MLU2 includes a 16-entry Memory Protection Unit (MPU) that enforces read/write/execute permissions per memory region for the e200z4 core and supports read/write access control for eDMA, FlexRay, and EBI masters. This hardware MPU is essential for ASIL-B decomposition and is complemented by CRC units, ECC on flash/SRAM, and a junction temperature sensor-all documented in the SPC5644AF0MLU2 safety manual for ISO 26262 compliance evidence.
How many analog-to-digital converter channels does the SPC5644AF0MLU2 support?
The SPC5644AF0MLU2 integrates two enhanced queued ADCs (eQADCs) supporting up to 40 multiplexed 12-bit input channels-20 per module-with expandability to 56 channels using external analog multiplexers. Each eQADC has six command queues, trigger/DMA support, and a minimum conversion time of 688 ns, enabling high-speed acquisition for engine knock detection and motor current sensing in the SPC5644AF0MLU2.
Is the SPC5644AF0MLU2 pin-compatible with other MPC56xx family members?
Yes, the SPC5644AF0MLU2 in 208 MAPBGA is ballmap-upward compatible with the standardized MPC5xxx family ballmap used for MPC5554, MPC5567, and MPC5666. It is also pinout-compatible with MPC5634M in LQFP packages, though direct substitution requires verification of voltage rail configurations, thermal design, and FlexRay/FlexCAN routing due to differing peripheral enablement across variants.
