Product details
Overview
TMX5700914APGEQQ1 from Texas Instruments is a dual-CPU lockstep ARM Cortex-R4F 32-bit safety microcontroller for automotive ASIL-D and IEC 61508 SIL-3 applications. It delivers 265 DMIPS at 160 MHz, integrates 1 MB flash with ECC, 128 KB RAM with ECC, and supports triple CAN (DCAN), dual 12-bit MibADCs (24+16 channels), seven ePWM modules, and two N2HET timing coprocessors. It is deployed in electric power steering and braking systems requiring real-time deterministic control and fault containment.
For engineers reviewing the TMX5700914APGEQQ1 datasheet, TMX5700914APGEQQ1 pinout, TMX5700914APGEQQ1 application, or TMX5700914APGEQQ1 equivalent, key selection criteria include lockstep CPU architecture, FMPLL clocking with slip detection, integrated ESM error signaling, and functional safety certification evidence for ISO 26262 ASIL-D development workflows.
Technical Context
The TMX5700914APGEQQ1 implements dual Cortex-R4F CPUs executing identical instructions in lockstep with hardware comparator monitoring; any divergence triggers ESM fault signaling via nERROR. Its memory subsystem applies ECC to 1 MB flash and 128 KB SRAM, while peripheral memories-including MibADC buffers and MibSPI RAM-use parity protection.
Real-time peripherals are hardware-protected: DMA uses dedicated MPU and parity-protected control RAM; N2HET modules include HTU with built-in MPU; ePWM features trip-zone inputs and synchronization with MibADC; and DCAN controllers support full CAN 2.0B at up to 1 Mbps with 64 mailboxes each.

Equivalent & Alternatives
The following parts are listed as comparable options for similar safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS570LS1227ZWT | 337-ball BGA, 180 MHz, 1280 KB flash, 192 KB RAM, 2× EMAC, 2× FlexRay - no LIN/SCI UART mode | Targeted at chassis domain controllers requiring Ethernet/FlexRay backbone connectivity, not LIN-peripheral integration | Select when Ethernet or FlexRay physical layer support is mandatory and board space allows BGA packaging. |
| TMS570LS0432PZ | 100-pin LQFP, 80 MHz, 384 KB flash, 32 KB RAM, 2× CAN, 1× eQEP, 1× N2HET (19 ch), no I2C | Lower-cost entry-level variant for non-ASIL-D or lower-performance safety functions (e.g., HVAC control, lighting) | Choose for cost-sensitive designs where reduced memory, peripheral count, and clock speed meet functional safety requirements. |
Compared with TMX5700914APGEQQ1, TMS570LS1227ZWT offers higher performance and networking capability but requires BGA assembly and lacks LIN; TMS570LS0432PZ reduces footprint and cost but sacrifices flash capacity, ADC channel count, and N2HET flexibility - making it unsuitable for full ASIL-D inverter control.

FAQ
What safety certifications apply to the TMX5700914APGEQQ1?
The TMX5700914APGEQQ1 is qualified for automotive applications per AEC-Q100 Grade 1 and supports ISO 26262 ASIL-D development with documented FMEDA, safety manuals, and diagnostic software libraries. TI provides certified compiler toolchains and safety documentation packages specifically for TMX5700914APGEQQ1 to accelerate functional safety certification.
Does the TMX5700914APGEQQ1 support LIN 2.1 communication?
Yes, the TMX5700914APGEQQ1 includes one SCI module that supports Local Interconnect Network (LIN) 2.1 protocol in addition to standard UART operation. This SCI can be configured as a LIN master or slave and complies with LIN 2.1 physical layer specifications, enabling direct connection to LIN sensors and actuators without external transceivers.
How many CAN interfaces does the TMX5700914APGEQQ1 support?
The TMX5700914APGEQQ1 integrates three independent DCAN controllers compliant with CAN 2.0A and 2.0B protocols. Each DCAN supports bit rates up to 1 Mbps and includes 64 dedicated mailboxes with parity protection, enabling robust multi-bus communication for distributed automotive networks.
What is the purpose of the N2HET modules in the TMX5700914APGEQQ1?
The TMX5700914APGEQQ1 includes two Next-Generation High-End Timer (N2HET) modules - N2HET1 (32 channels) and N2HET2 (18 channels) - designed to offload precise timing-critical tasks from the main CPU. They execute microcoded instructions to generate PWM waveforms, capture encoder edges, implement quadrature decoding, and manage complex I/O sequencing independently.
Can the TMX5700914APGEQQ1 operate with a single power supply?
No, the TMX5700914APGEQQ1 requires two separate supply domains: core voltage (VCC = 1.14–1.32 V) for CPU and memory, and I/O voltage (VCCIO = 3.0–3.6 V) for peripheral interfaces. These must be independently regulated; mixing supplies violates absolute maximum ratings and compromises ECC functionality and I/O signal integrity.
