Product details
Overview
TMS5700714APGEQQ1R from Texas Instruments is a dual-CPU lockstep ARM Cortex-R4F safety-certified microcontroller for automotive ASIL-D and industrial SIL-3 applications. It delivers 265 DMIPS at 160 MHz, integrates 768KB flash with ECC, 128KB RAM with ECC, and supports CAN 2.0B, LIN 2.1, and dual 12-bit MibADCs - deployed in electric power steering and braking systems.
For engineers reviewing the TMS5700714APGEQQ1R datasheet, TMS5700714APGEQQ1R pinout, TMS5700714APGEQQ1R application, or TMS5700714APGEQQ1R equivalent, this page provides verified functional safety architecture details, validated peripheral timing specs (ePWM deadband, N2HET channel count), package-specific I/O mapping (144-pin LQFP PGE), and ISO 26262-ready diagnostic coverage metrics.
Technical Context
The TMS5700714APGEQQ1R implements dual Cortex-R4F CPUs executing identical instructions in lockstep with real-time comparison and error signaling via dedicated nERROR pin. Its FMPLL generates system clocks up to 160 MHz with slip detection, while the Global Clock Module routes six clock sources across domains including CPU, peripheral, and ADC interfaces.
Functional safety is enforced through hardware BIST for CPU and RAM, ECC on flash and SRAM, parity on peripheral memories (MibSPI, CRC, HTU), and voltage/clock monitoring via integrated analog comparators. The Error Signaling Module (ESM) aggregates faults from all domains and asserts interrupt or external nERROR signal based on configurable severity levels.

Does the TMS5700714APGEQQ1R include hardware debug support?
Yes, the TMS5700714APGEQQ1R integrates IEEE 1149.1 JTAG boundary scan, ARM CoreSight debug components, and an Advanced JTAG Security Module (AJSM) for secure firmware debugging and programming. These features are fully operational in the 144-pin PGE package and documented in the TMS570LS0714 Technical Reference Manual.
How many CAN interfaces does the TMS5700714APGEQQ1R support?
The TMS5700714APGEQQ1R supports three DCAN controllers compliant with CAN 2.0A and 2.0B protocols, each with 64 parity-protected mailboxes and programmable bit timing. All three CAN interfaces are accessible in the 144-pin PGE package and operate at up to 1 Mbps in electrically noisy environments.
What is the role of the N2HET modules in the TMS5700714APGEQQ1R?
The TMS5700714APGEQQ1R includes two Next-Generation High-End Timer (N2HET) modules - N2HET1 (32 channels) and N2HET2 (18 channels) - each with 160-word instruction RAM and hardware angle generator. They execute timing-critical tasks like PWM generation, encoder pulse counting, and GPIO sequencing independently of the main CPU, reducing interrupt load and improving determinism in the TMS5700714APGEQQ1R.
