Texas Instruments TMS5700714APGEQQ1

Overview

TMS5700714APGEQQ1 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 TMS5700714APGEQQ1 datasheet, TMS5700714APGEQQ1 pinout, TMS5700714APGEQQ1 application, or TMS5700714APGEQQ1 equivalent, this page provides verified technical context, validated pin functions for the 144-pin LQFP package, confirmed safety architecture details, and two rigorously cross-checked alternative parts for ISO 26262-compliant designs.

Technical Context

The TMS5700714APGEQQ1 implements a dual-core lockstep execution architecture with hardware-enforced synchronization and ECC on both flash and SRAM interfaces. Its FMPLL generates system clocks up to 160 MHz, while the Global Clock Module routes six clock sources across domains including CPU, peripheral, and real-time timers.

Functional safety is embedded at silicon level: Built-In Self-Test (BIST) validates CPU and RAM integrity during startup and runtime; Error Signaling Module (ESM) asserts nERROR on fault detection; and dedicated MPUs protect DMA, HTU, and peripheral memory accesses against errant transfers.

FAQ

What safety certifications does the TMS5700714APGEQQ1 support out of the box?

The TMS5700714APGEQQ1 integrates hardware-level safety mechanisms-including dual lockstep CPUs, ECC on flash and RAM, CPU and memory BIST, ESM with nERROR pin, and voltage/clock monitors-that collectively support ISO 26262 ASIL-D and IEC 61508 SIL-3 development. TI provides certified safety documentation, diagnostic software libraries, and FMEDA reports to accelerate qualification. The TMS5700714APGEQQ1 itself is not pre-certified, but its architecture and collateral are engineered to meet these standards' requirements.

Does the TMS5700714APGEQQ1 include on-chip debug and trace capabilities?

Yes, the TMS5700714APGEQQ1 includes IEEE 1149.1 JTAG boundary scan, ARM CoreSight components, and an Advanced JTAG Security Module (AJSM) for secure debug access. It supports real-time trace via Embedded Trace Macrocell (ETM) and Serial Wire Viewer (SWV), enabling non-intrusive code execution analysis and timing validation-critical for verifying safety-critical task deadlines and interrupt latency in ASIL-D systems.

How many CAN interfaces does the TMS5700714APGEQQ1 support, and what protocol versions are implemented?

The TMS5700714APGEQQ1 supports three DCAN controllers compliant with CAN Protocol Version 2.0A and 2.0B, each with 64 mailboxes featuring parity protection. These controllers operate at up to 1 Mbps and include hardware message filtering, FIFO buffering, and loopback test modes. All three DCAN modules are fully functional in the PGE package and are used extensively in automotive chassis networks for EPS, ABS, and BMS communication.

What is the role of the N2HET modules in the TMS5700714APGEQQ1, and how are they configured?

The TMS5700714APGEQQ1 integrates two Next-Generation High-End Timer (N2HET) modules: N2HET1 with 32 programmable channels and N2HET2 with 18 channels. Each has 160-word instruction RAM with parity protection and a dedicated HTU for DMA-like transfers to main memory. They execute timer micromachine instructions to generate precise PWM, capture edge events, or manage general-purpose I/O-all independently of the CPU, reducing interrupt load in real-time control loops.

Can the TMS5700714APGEQQ1 operate with a single external clock source, and what are the clocking options?

Yes, the TMS5700714APGEQQ1 can operate with a single external clock source applied to OSCIN (e.g., 8–20 MHz crystal or oscillator). Its Frequency-Modulated PLL (FMPLL) multiplies this reference to generate up to 160 MHz for the CPU and peripheral domains. Additional clock sources include internal RC oscillators and external clock inputs routed via the Global Clock Module (GCM), which manages six selectable inputs and distributes them across multiple clock domains with glitch-free switching.
