Product details
Overview
SPC5644CK0MLT1R from NXP Semiconductors (formerly Freescale) is a 32-bit dual-core automotive MCU featuring e200z4 and e200z0 Power Architecture® cores, 1.5 MB flash with ECC, 192 KB RAM with ECC, and integrated Cryptographic Security Engine (CSE) for secure boot and firmware updates in body control modules. It supports FlexRay, Ethernet, 10x LINFlex, and 6x FlexCAN interfaces.
For engineers reviewing the SPC5644CK0MLT1R datasheet, SPC5644CK0MLT1R pinout, SPC5644CK0MLT1R application, or SPC5644CK0MLT1R equivalent, key selection criteria include CSE hardware acceleration for secure communication, dual-core real-time I/O management, FlexRay/Ethernet coexistence for gateway diagnostics, and 176-pin LQFP package compatibility with MPC560xB/C migration paths.
Technical Context
The SPC5644CK0MLT1R implements a dual-core architecture where the e200z4 core (up to 120 MHz) handles main application tasks while the e200z0 core (up to 80 MHz) manages peripheral I/O and low-latency communication stacks. Its crossbar switch enables concurrent memory and peripheral access without arbitration bottlenecks.
Security is enforced via the dedicated CSE module supporting AES-128/256, SHA-256, RSA-2048, and true random number generation - all isolated from software execution domains. The Memory Protection Unit (MPU) and ECC on both flash and RAM ensure functional safety compliance per ISO 26262 ASIL-B requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive gateway and secure body control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5644B | Single e200z4 core (no e200z0 companion), 1.5 MB flash, 128 KB RAM, no Ethernet support. | Limited to non-diagnostic gateway roles; cannot handle concurrent Ethernet/FlexRay traffic or secure OTA via Ethernet. | Select when cost-sensitive BCM designs omit Ethernet diagnostics and require only CAN/LIN/FlexRay bridging. |
| SPC5645CK0MLT1R | Same dual-core architecture but with 2 MB flash, 256 KB RAM, and optional CSE (not guaranteed in all variants). | Enables larger AUTOSAR BSW stacks and extended log storage for regulatory reporting; CSE availability depends on mask set. | Select when future-proofing for larger firmware images or when CSE is confirmed enabled in production mask revision. |
Compared with MPC5644B and SPC5645CK0MLT1R, the SPC5644CK0MLT1R uniquely balances dual-core performance, Ethernet/FlexRay coexistence, and guaranteed CSE implementation - making it optimal for ASIL-B-compliant diagnostic gateways requiring secure, low-latency multi-bus bridging.

FAQ
What is the maximum operating frequency of the SPC5644CK0MLT1R cores?
The SPC5644CK0MLT1R integrates two Power Architecture® cores: the e200z4 core operates up to 120 MHz for main application processing, and the e200z0 core runs up to 80 MHz for dedicated I/O and communication stack management. Both frequencies are validated across the full –40 °C to +125 °C temperature range and supported by the on-chip FMPLL with spread-spectrum modulation to reduce EMI.
Does the SPC5644CK0MLT1R include hardware error correction for memory?
Yes, the SPC5644CK0MLT1R includes ECC on both its 1.5 MB flash memory and 192 KB SRAM. Flash ECC supports single-bit correction and double-bit detection for program/erase cycles, while SRAM ECC provides real-time correction during read/write operations - essential for ISO 26262 ASIL-B compliance in automotive gateway applications.
Is Ethernet support included in the SPC5644CK0MLT1R?
Yes, the SPC5644CK0MLT1R includes a fully integrated Ethernet FEC (Fast Ethernet Controller) compliant with IEEE 802.3. It supports MII/RMII interfaces, auto-negotiation, and hardware checksum offload - enabling high-speed diagnostic communication, firmware updates, and vehicle-to-cloud connectivity in automotive gateway systems.
What security features does the SPC5644CK0MLT1R provide beyond software encryption?
The SPC5644CK0MLT1R includes a dedicated Cryptographic Security Engine (CSE) with hardware-accelerated AES-128/256, SHA-256, RSA-2048, and true random number generation. Unlike software-only approaches, the CSE isolates key storage and crypto operations from the main CPU domain, preventing extraction via debugger access or memory dump - a requirement for UNECE R155-compliant secure boot in SPC5644CK0MLT1R-based systems.
Which package type is used by the SPC5644CK0MLT1R?
The SPC5644CK0MLT1R is packaged in a 176-pin LQFP (24 mm × 24 mm, 0.5 mm pitch) with exposed thermal pad. This package is pin-compatible with other MPC564x devices in the same pin count, including MPC5644B and MPC5645C, enabling layout reuse and migration paths within the Qorivva family.
