It operates at up to 66 MHz, supports 3.0–5.5 V supply, and targets engine control units (ECUs) requiring ASIL-B functional safety compliance.

For engineers reviewing the SPC5517EBVLQ66R datasheet, SPC5517EBVLQ66R pinout, SPC5517EBVLQ66R application, or SPC5517EBVLQ66R equivalent, key selection criteria include its LQFP-176 package, 66 MHz core frequency, integrated FMPLL, FlexCAN buffer configurability, and Nexus Class Two Plus debug interface for real-time trace and calibration in production ECU validation.

Technical Context

The SPC5517EBVLQ66R implements a single-issue e200z1 CPU core compliant with Power Architecture embedded category and supports Variable Length Encoding (VLE) for reduced code footprint. Its crossbar switch enables concurrent access to flash, SRAM, and peripherals by multiple bus masters including eDMA and FlexCAN controllers.

It integrates an FMPLL for jitter-tolerant clock synthesis, a memory protection unit (MPU) with 16 region descriptors, and boot assist via CAN/SCI serial link. The device includes eMIOS200 for flexible timer functions, DSPI modules supporting classic and modified SPI transfer formats, and MLB emulation logic using two DSPIs and system RAM.

FAQ

What is the maximum operating frequency of the SPC5517EBVLQ66R?

The SPC5517EBVLQ66R operates at a maximum core frequency of 66 MHz. This frequency is achieved using the integrated Frequency Modulated Phase-Locked Loop (FMPLL), which synthesizes stable clock signals from low-frequency crystal or RC oscillator sources. The 66 MHz rating is validated across the full automotive temperature range (−40°C to 125°C) and ensures deterministic execution of time-critical engine control algorithms in the SPC5517EBVLQ66R.

Does the SPC5517EBVLQ66R support functional safety standards such as ISO 26262?

Yes, the SPC5517EBVLQ66R is designed to support ISO 26262 ASIL-B compliance. It includes hardware features essential for safety mechanisms: Memory Protection Unit (MPU) with 16 region descriptors, Error Correction Code (ECC) on both flash and SRAM, lock-step capable peripherals, and Nexus Class Two Plus debug interface for runtime verification. These capabilities are documented in NXP's SPC5517 safety manual and enable systematic development of safety-critical software for the SPC5517EBVLQ66R.

What package type and pin count does the SPC5517EBVLQ66R use?

The SPC5517EBVLQ66R uses a 176-pin LQFP package with 24 mm × 24 mm body dimensions and 0.5 mm lead pitch. This package is explicitly listed in the MPC5510 family datasheet (Rev. 5, Table 26) and confirmed for the SPC5517 variant. The LQFP-176 provides robust thermal performance and manufacturability for automotive-grade reflow assembly, and its pinout is fully compatible with NXP's reference design layouts for ECU applications using the SPC5517EBVLQ66R.

How many CAN interfaces does the SPC5517EBVLQ66R integrate, and what are their key capabilities?

The SPC5517EBVLQ66R integrates six FlexCAN modules. Each supports CAN 2.0A/B protocol, configurable message buffers (up to 64 per module), programmable bit timing, and automatic retransmission. They operate independently with separate clock domains and interrupt vectors, enabling concurrent communication on multiple vehicle networks - for example, one for powertrain, one for chassis, and others for body or infotainment domains - all managed within a single SPC5517EBVLQ66R device.

Is the SPC5517EBVLQ66R pin-compatible with other members of the MPC5510 family?

No, the SPC5517EBVLQ66R is not universally pin-compatible across the MPC5510 family. While it shares the LQFP-176 footprint with the MPC5510 variant in that package, pin functions differ significantly due to feature configuration - for example, MLB emulation pins (PE0–PE5) and FlexRay I/O (PC0–PC15) are enabled only in specific SPC5517 configurations. Direct substitution requires verification against the SPC5517-specific signal list and electrical characteristics, not the generic MPC5510 datasheet alone.
