Product details
Overview
TMS5703137DZWTQQ1 from Texas Instruments is an automotive-grade 32-bit RISC flash microcontroller with dual lockstep ARM Cortex-R4F CPUs, 3 MB ECC-protected flash, 256 KB ECC RAM, and integrated safety features including BIST, voltage/clock monitoring, and error signaling. It delivers 298 DMIPS at 180 MHz and supports real-time control in braking systems, electric power steering, and battery management.
For engineers reviewing the TMS5703137DZWTQQ1 datasheet, TMS5703137DZWTQQ1 pinout, TMS5703137DZWTQQ1 application, or TMS5703137DZWTQQ1 equivalent, key selection criteria include ASIL-D compliance support, dual-CPU lockstep architecture, EMAC/FlexRay/DCAN interface availability, and N2HET timer channel count for deterministic timing in safety-critical automotive subsystems.
Technical Context
The TMS5703137DZWTQQ1 implements a dual-core lockstep execution model where both Cortex-R4F CPUs execute identical instructions and compare results in real time to detect transient faults. Its safety architecture includes on-chip BIST for CPU and RAM, ECC on flash and SRAM, parity protection on peripheral memories (MibADC buffers, N2HET RAM, message RAM), and dedicated Error Signaling Module (ESM) with external ERROR pin assertion.
It integrates two Next Generation High-End Timer (N2HET) modules-N2HET1 with 32 programmable channels and N2HET2 with 18 channels-each backed by 160-word instruction RAM with parity and a dedicated HTU with MPU. The device also includes three DCAN controllers compliant with CAN 2.0B, a 10/100 Mbps Ethernet MAC supporting MII/RMII/MDIO, and dual 12-bit MibADCs with 24 total channels and 64-word parity-protected result buffers each.

Equivalent & Alternatives
The following parts are listed as comparable options for similar safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS570LS3137PGE | 144-pin LQFP package; reduced I/O count (58 GPIO vs. 144); no EMIF; same CPU, memory, and peripheral IP | Targeted at space-constrained but less I/O-intensive applications (e.g., compact body control modules) | Select when board area is limited and external memory expansion is unnecessary. |
| TMS570LS3135ZWT | Same ZWT package but lower frequency (160 MHz vs. 180 MHz); identical peripheral set and safety architecture | Suitable for cost-optimized designs where full 298 DMIPS is not required (e.g., mid-tier ADAS ECUs) | Choose when thermal budget or power consumption constraints favor reduced clock rate without sacrificing safety features. |
Compared with TMS5703137DZWTQQ1, the PGE variant trades I/O and EMIF capability for smaller footprint, while the LS3135 offers identical safety and peripheral functionality at lower clock speed-both retain full ASIL-D readiness but address distinct mechanical and performance trade-offs.

FAQ
What safety certifications does the TMS5703137DZWTQQ1 support?
The TMS5703137DZWTQQ1 is architected to support ISO 26262 ASIL-D compliance through dual lockstep CPUs, ECC on all memory, BIST, ESM, and hardware monitors. TI provides safety manuals, FMEDA reports, and diagnostic software libraries to accelerate certification-TMS5703137DZWTQQ1 itself is not pre-certified, but its design meets requirements for ASIL-D decomposition in end-system certification.
Does the TMS5703137DZWTQQ1 include an external memory interface?
Yes, the TMS5703137DZWTQQ1 includes a 16-bit External Memory Interface (EMIF) supporting SDRAM, asynchronous memories, peripherals, and FPGA devices. This interface is present in the ZWT package and enables off-chip expansion for applications requiring additional code space or data buffering beyond on-chip 3 MB flash and 256 KB RAM.
How many CAN controllers are integrated into the TMS5703137DZWTQQ1?
The TMS5703137DZWTQQ1 integrates three DCAN controllers compliant with CAN 2.0B protocol, each supporting up to 1 Mbps communication. These controllers operate independently and support message objects with parity protection, making them suitable for distributed automotive networks such as powertrain, chassis, and body domains.
What is the role of the N2HET modules in the TMS5703137DZWTQQ1?
The TMS5703137DZWTQQ1 includes two Next Generation High-End Timer (N2HET) modules-N2HET1 with 32 channels and N2HET2 with 18 channels-that serve as autonomous timing coprocessors. They execute timing sequences (e.g., PWM, capture, compare) without CPU intervention, reducing latency and jitter for real-time control tasks like motor commutation and sensor signal conditioning.
Is the TMS5703137DZWTQQ1 pin-compatible with other TMS570 family members?
The TMS5703137DZWTQQ1 shares the 337-ball ZWT package with other TMS570LS3137 variants (e.g., TMS570LS3137ZWT) and is pin-compatible within that package group. However, it is not pin-compatible with PGE-package variants or higher-feature devices like TMS570LC4357ZWT due to differing ball maps, I/O allocations, and peripheral enablement.
