Product details
Overview
TMS5700714APZQQ1 from Texas Instruments is an automotive-grade, safety-critical 32-bit ARM Cortex-R4F microcontroller with dual lockstep CPUs, 768KB flash (ECC-protected), 128KB RAM (ECC-protected), and integrated functional safety features including BIST, voltage/clock monitoring, and error signaling. It delivers 265 DMIPS at 160 MHz and targets real-time control in electric power steering, braking systems, and battery-management systems.
For engineers reviewing the TMS5700714APZQQ1 datasheet, TMS5700714APZQQ1 pinout, TMS5700714APZQQ1 application, or TMS5700714APZQQ1 equivalent, this page provides verified technical context, package-specific pin mapping for the 100-pin LQFP (PZ), key safety-certified specifications, and validated alternative parts for ISO 26262-compliant designs.
Technical Context
The TMS5700714APZQQ1 implements a dual-core lockstep architecture where both Cortex-R4F CPUs execute identical instructions and compare results in real time to detect transient or permanent faults. Its FMPLL generates internal clocks up to 160 MHz, while the Global Clock Module routes six clock sources across domains including CPU, peripheral, and debug subsystems.
Functional safety is enforced via ECC on flash and RAM, parity on peripheral memories (MibADC buffers, MibSPI RAM), built-in self-test for CPU and SRAM, and an Error Signaling Module (ESM) that asserts nERROR on fault detection. The device supports ISO 26262 ASIL-D development with diagnostic coverage enabled by hardware modules including CRC, HTU, and dedicated MPU for DMA/N2HET transfers.

FAQ
What safety certifications apply to the TMS5700714APZQQ1?
The TMS5700714APZQQ1 is qualified for automotive applications per AEC-Q100 Grade 1 (–40°C to +125°C) and supports ISO 26262 ASIL-D development with hardware safety mechanisms including lockstep CPUs, ECC memory, BIST, and ESM. TI provides certified safety documentation, FMEDA reports, and diagnostic software libraries for TMS5700714APZQQ1-based systems.
Does the TMS5700714APZQQ1 support LIN communication?
Yes, the TMS5700714APZQQ1 integrates one SCI module with LIN 2.1 protocol support, enabling it to operate as either LIN master or slave. The LIN interface shares pins with UART functionality and supports standard NRZ encoding, automatic baud rate detection, and LIN diagnostic services - all accessible through the TMS5700714APZQQ1's peripheral configuration registers.
How many CAN interfaces does the TMS5700714APZQQ1 include?
The TMS5700714APZQQ1 includes three DCAN controllers compliant with CAN 2.0A and 2.0B protocols, each supporting up to 64 mailboxes with parity protection. These CAN interfaces operate at rates up to 1 Mbps and are fully integrated into the device's safety architecture, with error counters and status reporting accessible via the TMS5700714APZQQ1's register map.
What is the purpose of the N2HET modules in the TMS5700714APZQQ1?
The TMS5700714APZQQ1 features two Next-Generation High-End Timer (N2HET) modules - N2HET1 (32 channels) and N2HET2 (18 channels) - which serve as autonomous timing coprocessors. They execute programmable microcode to generate precise PWM waveforms, capture edge events, or manage quadrature encoder signals without CPU intervention, reducing latency and improving determinism in real-time control loops.
Can the TMS5700714APZQQ1 operate without external crystal?
No - the TMS5700714APZQQ1 requires an external crystal (e.g., 20 MHz) connected to OSCIN/OSCOUT for reliable operation in safety-critical modes. While an internal oscillator exists, TI documentation explicitly states it is not used in lockstep or safety-monitoring contexts; the FMPLL must be driven by the external crystal to meet timing and diagnostic requirements of the TMS5700714APZQQ1.
