Product details
Overview
TMX5700714ZWTQQ1 from Texas Instruments is a dual-CPU lockstep ARM Cortex-R4F 32-bit safety MCU for automotive ASIL-D systems, featuring 768KB flash with ECC, 128KB RAM with ECC, 160-MHz operation, and integrated diagnostics including BIST, voltage/clock monitoring, and error signaling. It serves as the primary control unit in electric power steering and braking systems.
For engineers reviewing the TMX5700714ZWTQQ1 datasheet, TMX5700714ZWTQQ1 pinout, TMX5700714ZWTQQ1 application, or TMX5700714ZWTQQ1 equivalent, this page delivers verified functional safety parameters, validated N2HET/ePWM/DCAN peripheral capabilities, package-specific terminal mapping, and ISO 26262-compliant architecture details required for safety-critical design validation and component selection.
Technical Context
The TMX5700714ZWTQQ1 implements dual Cortex-R4F CPUs executing identical instructions in lockstep with real-time comparison, supported by ECC on all flash and SRAM interfaces and parity protection across peripheral memories. Its FMPLL generates system clocks up to 160 MHz with slip detection, while the Global Clock Module routes six clock sources to domain-specific peripherals.
Functional safety is enforced via dedicated hardware: the Error Signaling Module (ESM) asserts nERROR on fault detection; Built-In Self-Test covers CPU and RAM; and the Digital Windowed Watchdog provides time-bound supervision. All critical peripherals-including DCAN, N2HET, ePWM, and MibADC-feature parity/ECC protection and are accessible through MPU-secured DMA channels.

The TMX5700714ZWTQQ1 is qualified for ASIL-D per ISO 26262 and SIL-3 per IEC 61508. Its lockstep CPU, ECC memory, BIST, and ESM are pre-verified components within TI's SafeTI™ documentation package, enabling certified safety element out of context (SEooC) reuse in customer systems. TMX5700714ZWTQQ1 meets these standards without requiring additional external safety monitors.
Does the TMX5700714ZWTQQ1 support LIN communication?
Yes, the TMX5700714ZWTQQ1 includes one SCI interface configurable as LIN 2.1 compliant transceiver, supporting baud rates up to 20 kbps with automatic sync-break detection and checksum validation. This LIN channel operates independently of the three DCAN controllers and is implemented in hardware without CPU intervention, ensuring deterministic timing for body electronics communication.
How many CAN interfaces does the TMX5700714ZWTQQ1 provide?
The TMX5700714ZWTQQ1 integrates three DCAN controllers compliant with CAN 2.0A and 2.0B protocols, each supporting up to 1 Mbps data rate and 64 mailboxes with parity-protected RAM. These controllers operate independently with separate message objects and filtering logic, enabling simultaneous communication with multiple ECUs in distributed automotive networks.
What is the maximum operating frequency of the TMX5700714ZWTQQ1?
The TMX5700714ZWTQQ1 operates at a maximum system clock frequency of 160 MHz, achieved via its Frequency-Modulated Phase-Locked Loop (FMPLL) with built-in slip detector. This frequency enables 265 DMIPS performance from the dual Cortex-R4F cores, sufficient for real-time execution of complex motor control and sensor fusion algorithms in safety-critical applications.
Is external memory required for the TMX5700714ZWTQQ1 to function?
No, the TMX5700714ZWTQQ1 contains all necessary memory on-die: 768KB flash with ECC for program storage, 128KB RAM with ECC for runtime data, and 64KB flash for emulated EEPROM. These integrated memories eliminate the need for external SDRAM or NOR flash in most automotive control applications, reducing BOM cost and PCB complexity while maintaining ASIL-D compliance.
