Overview
TMS5700914APGEQQ1 from Texas Instruments is a dual-CPU lockstep ARM Cortex-R4F 32-bit safety microcontroller for automotive ASIL-D and industrial SIL-3 applications, featuring 1 MB flash with ECC, 128 KB RAM with ECC, 160-MHz operation, and integrated diagnostics including BIST, voltage/clock monitoring, and error signaling via nERROR pin - deployed in electric power steering and braking systems.
For engineers reviewing the TMS5700914APGEQQ1 datasheet, TMS5700914APGEQQ1 pinout, TMS5700914APGEQQ1 application, or TMS5700914APGEQQ1 equivalent, this page delivers verified functional safety architecture details, real-time peripheral configuration (ePWM/eCAP/N2HET), ISO 26262-ready memory protection, and package-specific I/O mapping for the 144-pin LQFP (PGE) variant.
Technical Context
The TMS5700914APGEQQ1 implements dual ARM Cortex-R4F CPUs executing identical instructions in lockstep with hardware comparison logic to detect divergence, supported by ECC on all flash and SRAM interfaces and parity on peripheral memories. Its FMPLL generates internal clocks up to 160 MHz while enabling frequency modulation for EMI reduction.
Real-time control is enabled by two N2HET modules (32 + 18 programmable channels), seven ePWM modules with deadband generation and trip-zone protection, six eCAP modules, two eQEP modules, and dual 12-bit MibADCs (24 + 16 channels, 16 shared) - all accessible via a 16-channel DMA controller with MPU-protected transfers.

FAQ
What safety certifications apply to the TMS5700914APGEQQ1?
The TMS5700914APGEQQ1 is qualified for automotive safety integrity level ASIL-D per ISO 26262 and industrial SIL-3 per IEC 61508. It includes hardware safety mechanisms such as dual lockstep CPUs, ECC on flash and RAM, BIST, clock/voltage monitors, and ESM with nERROR output - all documented in TI's Functional Safety Manual SPNU634.
Does the TMS5700914APGEQQ1 support CAN FD?
No, the TMS5700914APGEQQ1 integrates three DCAN controllers compliant only with CAN 2.0A and 2.0B protocols (up to 1 Mbps). It does not implement CAN FD physical layer or protocol features. For CAN FD support, consider TI's TCAN4550 or newer Hercules TMS570 variants with CAN FD peripherals.
What is the purpose of the N2HET modules in the TMS5700914APGEQQ1?
The TMS5700914APGEQQ1 includes two N2HET modules (N2HET1 with 32 channels, N2HET2 with 18 channels) that serve as programmable real-time timing coprocessors. They execute microcode to generate precise PWM waveforms, capture edge events, or manage encoder signals - offloading timing-critical tasks from the main Cortex-R4F CPU and improving determinism.
How is flash memory protected against corruption in the TMS5700914APGEQQ1?
The TMS5700914APGEQQ1 implements ECC (Error Correction Code) on its entire 1 MB flash array, providing single-bit error correction and double-bit error detection. This protection is active during all read, program, and erase operations and is enforced in hardware - ensuring data integrity even under radiation or voltage disturbance events common in automotive environments.
Can the TMS5700914APGEQQ1 operate with a 25-MHz crystal?
Yes, the TMS5700914APGEQQ1 supports crystal frequencies from 4 MHz to 25 MHz on the OSCIN/OSCOUT pins. The internal FMPLL multiplies this reference to generate the 160-MHz system clock. TI recommends using a fundamental-mode crystal with appropriate load capacitance and stability specifications per Section 6.6 of the SPNS225D datasheet.
