Product details
Overview
TMS5701115CPGEQQ1 from Texas Instruments is an automotive-grade 32-bit RISC flash microcontroller with dual lockstep ARM Cortex-R4F CPUs, 1 MB ECC-protected flash, 128 KB ECC RAM, and integrated safety features including BIST, voltage/clock monitoring, and error signaling - designed for ABS, EPS, and HEV inverter control systems.
For engineers reviewing the TMS5701115CPGEQQ1 datasheet, TMS5701115CPGEQQ1 pinout, TMS5701115CPGEQQ1 application, or TMS5701115CPGEQQ1 equivalent, key selection criteria include ASIL-D compliance support, dual-CPU lockstep execution, N2HET timing coprocessor count, ePWM deadband generation capability, and FlexRay/DCAN interface availability in the 144-pin LQFP package.
Technical Context
The TMS5701115CPGEQQ1 implements a safety-critical architecture with two identical ARM Cortex-R4F cores executing identical instructions in lockstep, where mismatch detection triggers ESM fault reporting. It integrates two N2HET modules (N2HET1: 32 channels; N2HET2: 18 channels), each with dedicated HTU for DMA-like transfers and built-in MPU protection.
Its real-time control subsystem includes seven ePWM modules supporting high-side/low-side switching with trip-zone protection, six eCAP modules for precise edge capture, two eQEP modules for motor position feedback, and dual 12-bit MibADCs (24 total inputs, 64-word parity-protected buffers) synchronized to ePWM events.

The TMS5701115CPGEQQ1 is architected to support ISO 26262 ASIL-D compliance through integrated features including dual lockstep CPUs, ECC on flash and RAM, BIST for CPU and memory, parity-protected peripheral RAM, and ESM with nERROR pin. Texas Instruments provides FMEDA reports, safety manuals, and diagnostic software libraries to accelerate customer certification - the TMS5701115CPGEQQ1 itself is not pre-certified, but its safety mechanisms are validated for ASIL-D system-level implementation.
Does the TMS5701115CPGEQQ1 include hardware support for motor control PWM generation?
Yes, the TMS5701115CPGEQQ1 integrates seven enhanced PWM (ePWM) modules with complementary outputs, programmable deadband, trip-zone inputs for immediate fault response, and hardware synchronization to MibADC conversion triggers - enabling precise, low-latency motor control without CPU overhead. Each ePWM module supports high-side and low-side switching, making the TMS5701115CPGEQQ1 suitable for three-phase inverter gate driving in EPS and HEV applications.
What is the difference between the TMS5701115CPGEQQ1 and TMS570LS1115PGE?
The TMS5701115CPGEQQ1 is the automotive-qualified, AEC-Q100 Grade 1 (–40°C to +125°C) version of the TMS570LS1115PGE industrial part. It includes extended temperature range validation, enhanced ESD robustness, automotive-specific qualification testing (HTOL, uHAST), and full PPAP documentation support - all while sharing identical electrical specifications, pinout, and firmware compatibility with the TMS570LS1115PGE.
Can the TMS5701115CPGEQQ1 interface directly with FlexRay networks?
Yes, the TMS5701115CPGEQQ1 includes a fully integrated dual-channel FlexRay controller compliant with FlexRay v2.1, supporting static and dynamic segments, 10 Mbps per channel, and autonomous data transfers via the dedicated FlexRay Transfer Unit (FTU). The FTU handles message buffering and memory mapping independently, freeing the CPU for safety-critical tasks - a key capability confirmed in the TMS5701115CPGEQQ1 datasheet Section 7.7.
How does the N2HET subsystem enhance real-time performance in the TMS5701115CPGEQQ1?
The TMS5701115CPGEQQ1 features two Next Generation High-End Timer (N2HET) modules - N2HET1 with 32 programmable I/O channels and N2HET2 with 18 - each equipped with dedicated HTU for DMA-style memory transfers and built-in MPU. These timers execute microcoded timing sequences offloading complex waveform generation (e.g., multi-phase PWM, encoder emulation) from the main CPU, achieving sub-microsecond timing resolution and deterministic behavior essential for motor control and safety actuation in the TMS5701115CPGEQQ1.
