NXP Semiconductors SPC5674FAMVR3

Overview

SPC5674FAMVR3 from NXP Semiconductors is a 32-bit Power Architecture® e200z7 dual-issue microcontroller designed for automotive powertrain and chassis control. It integrates 4 MB on-chip flash, 256 KB SRAM (including 32 KB standby RAM), dual eTPU2 units (64 total channels), four FlexCAN modules, and dual-channel FlexRay - enabling deterministic real-time control in engine management systems.

For engineers reviewing the SPC5674FAMVR3 datasheet, SPC5674FAMVR3 pinout, SPC5674FAMVR3 application, or SPC5674FAMVR3 equivalent, key selection criteria include its 200 MHz nominal/200 MHz max operating frequency, 416-ball TEPBGA package (27 mm × 27 mm), -40 °C to 125 °C automotive temperature grade, and absence of External Bus Interface (EBI) - critical for space-constrained ECU designs requiring high integration without external memory expansion.

Technical Context

The SPC5674FAMVR3 implements a dual-issue e200z7 core with VLE instruction encoding and SPE2 DSP extensions, enabling efficient code density and signal processing for motor control algorithms. Its crossbar switch architecture allows concurrent access to flash, SRAM, and peripherals by multiple bus masters including two eDMA2 controllers (64- and 32-channel).

It features two second-generation eTPU2 units sharing 24 KB code RAM and 6 KB parameter RAM, supporting precise timing-critical functions like ignition timing and fuel injection. The device includes four eQADC modules (64 total analog channels), four DSPI interfaces, three eSCI ports, and Nexus IEEE-ISTO 5001 debug support - all optimized for ASIL-B/D automotive safety compliance.

Key Specifications

Pinout & Package

SPC5674FAMVR3 uses a 416-ball TEPBGA package (27 mm × 27 mm, Pb-free), specified in NXP's MPC5674F Data Sheet Rev. 11, Section 3.2. Pin assignments are defined across Figures 6–10, with primary I/O grouped by function: analog inputs (ANA0–ANA39, ANB0–ANB23), eTPU/EMIOS signals (ETPUA0–ETPUA31, ETPUB0–ETPUB31, EMIOS0–EMIOS31), communication interfaces (FlexCAN, FlexRay, DSPI, eSCI), and power/ground (VDD, VSS, VDDA, VSSA).

FAQ

What is the maximum operating frequency of the SPC5674FAMVR3?

The SPC5674FAMVR3 has a nominal and maximum operating frequency of 200 MHz - unlike higher-grade variants such as MPC5674FK0MVR3 (264 MHz nominal), it does not support frequency modulation. This fixed-frequency operation ensures predictable timing behavior for safety-critical automotive control loops, and is validated across the full -40 °C to 125 °C temperature range specified in the MPC5674F Data Sheet Rev. 11.

Does the SPC5674FAMVR3 include an External Bus Interface (EBI)?

No, the SPC5674FAMVR3 does not include an External Bus Interface. Per Table 2 in the MPC5674F Data Sheet Rev. 11, EBI is only available on 516-ball TEPBGA packages (e.g., SPC5674FK0MVY3). The SPC5674FAMVR3 uses a 416-ball TEPBGA package with no EBI functionality - confirming its design focus on highly integrated, flash-resident applications without external memory expansion.

What is the flash memory size and endurance specification for the SPC5674FAMVR3?

The SPC5674FAMVR3 integrates 4 MB of on-chip C90 flash memory, supporting read-while-program and read-while-erase operations. According to Section 4.10 of the MPC5674F Data Sheet Rev. 11, it guarantees ≥100,000 program/erase cycles and data retention of ≥20 years at 125 °C junction temperature - meeting automotive AEC-Q100 Grade 1 requirements for long-life powertrain ECUs.

How many eTPU2 channels does the SPC5674FAMVR3 support, and how is RAM allocated?

The SPC5674FAMVR3 supports 64 eTPU2 channels across two independent 32-channel units (eTPU_A and eTPU_B), sharing 24 KB of code RAM and 6 KB of parameter RAM. As documented in Section 2.1 and Table 2 of the MPC5674F Data Sheet Rev. 11, this shared RAM architecture enables tightly coupled timing tasks - such as synchronized fuel injector firing and spark timing - without CPU intervention or inter-unit data copying.

Is the SPC5674FAMVR3 qualified for automotive applications, and what is its temperature grade?

Yes, the SPC5674FAMVR3 is fully qualified for automotive use under AEC-Q100 Grade 1, with an operating ambient temperature range of -40 °C to 125 °C. Its part number suffix "M" indicates full automotive qualification (per Figure 1 and Table 1 in the MPC5674F Data Sheet Rev. 11), and the "VR" package identifier confirms the 416-ball Pb-free TEPBGA - making it suitable for under-hood engine control and transmission applications requiring sustained high-temperature reliability.
