Product details
Overview
TMS5701115BZWTQQ1 from Texas Instruments is an automotive-grade 32-bit RISC flash microcontroller built on the ARM Cortex-R4F core, featuring dual lockstep CPUs, 1 MB ECC-protected flash, 128 KB ECC-protected RAM, and integrated safety mechanisms including BIST, voltage/clock monitoring, and error signaling. It delivers 298 DMIPS at 180 MHz and targets real-time motor control and safety-critical vehicle subsystems.
For engineers reviewing the TMS5701115BZWTQQ1 datasheet, TMS5701115BZWTQQ1 pinout, TMS5701115BZWTQQ1 application, or TMS5701115BZWTQQ1 equivalent, key selection criteria include ASIL-D compliance support, dual-core lockstep architecture, N2HET timing coprocessor count, ePWM deadband generation capability, and FlexRay/DCAN interface availability for automotive networked control systems.
Technical Context
The TMS5701115BZWTQQ1 implements a dual-CPU lockstep execution model with hardware BIST and ECC on both flash and SRAM to meet ISO 26262 ASIL-D requirements. Its safety architecture includes dedicated Error Signaling Module (ESM) with nERROR output, parity protection on peripheral memories, and loopback-capable I/O for fault detection.
Real-time control is enabled by two independent Next Generation High-End Timer (N2HET) modules - N2HET1 with 32 programmable channels and N2HET2 with 18 channels - each backed by dedicated HTU for DMA-style data transfers and MPU-protected memory access. The device integrates seven ePWM modules with trip-zone protection and synchronization to MibADC for precise motor phase control.

FAQ
What safety certifications does the TMS5701115BZWTQQ1 support?
The TMS5701115BZWTQQ1 is architected to support ISO 26262 ASIL-D compliance through dual lockstep CPUs, on-chip BIST, ECC on flash and RAM, parity on peripheral memories, and dedicated Error Signaling Module (ESM). While certification is system-level, TI provides safety manuals, FMEDA reports, and diagnostic software libraries to accelerate TMS5701115BZWTQQ1-based design validation per ISO 26262 Part 5 and Part 6 requirements.
Does the TMS5701115BZWTQQ1 include hardware support for motor control?
Yes, the TMS5701115BZWTQQ1 includes seven Enhanced PWM (ePWM) modules with deadband generation, trip-zone inputs, and synchronization to MibADC - enabling precise three-phase inverter control. It also integrates six eCAP modules for encoder position capture and two eQEP modules for quadrature decoding, all coordinated by two N2HET timing coprocessors for sub-microsecond timing accuracy in TMS5701115BZWTQQ1-based motor drives.
What communication interfaces are available on the TMS5701115BZWTQQ1?
The TMS5701115BZWTQQ1 features three DCAN controllers (CAN 2.0A/B), two FlexRay channels (10 Mbps each), three MibSPI modules, two standard SPI interfaces, one LIN interface, two UART/SCI ports, one I2C module, and an External Memory Interface (EMIF). These interfaces support redundant, time-triggered, and event-driven communication essential for TMS5701115BZWTQQ1 deployment in automotive domain controllers and safety systems.
How is memory protected on the TMS5701115BZWTQQ1?
Memory protection on the TMS5701115BZWTQQ1 is implemented at multiple levels: ECC on 1 MB flash and 128 KB RAM corrects single-bit errors and detects double-bit errors; parity protection covers peripheral memories including MibADC buffers and message RAM; a 12-region MPU enforces access rights for CPU and DMA; and the Parameter Overlay Module (POM) enables runtime remapping to prevent unauthorized flash writes - all contributing to TMS5701115BZWTQQ1's ASIL-D readiness.
What is the operating voltage range for the TMS5701115BZWTQQ1?
The TMS5701115BZWTQQ1 requires two independent supply domains: core voltage (VCC) from 1.14 V to 1.32 V for the Cortex-R4F CPU and internal logic, and I/O voltage (VCCIO) from 3.0 V to 3.6 V for peripheral interfaces and GPIO. This dual-rail design isolates noise-sensitive core logic from higher-voltage I/O, and the device includes on-chip voltage monitors to detect out-of-spec conditions and trigger ESM responses - critical for TMS5701115BZWTQQ1 reliability in automotive environments.
