Applications
The TMS570LS0714PZ is purpose-built for safety-critical embedded control applications including automotive brake-by-wire, electric power steering, and airbag control units that must meet ISO 26262 ASIL requirements. Its ARM Cortex-R4F core with lockstep execution and built-in self-test (BIST) functions satisfies the hardware diagnostic coverage mandated by IEC 61508 SIL 2 and SIL 3 industrial safety standards for machine controllers and servo drives. The device is also used in aerospace flight control computers, railway signalling systems, and medical life-support equipment where real-time response at 80 MHz and deterministic interrupt latency are mandatory.

Frequently Asked Questions
What CPU architecture and maximum clock speed does TMS570LS0714PZ offer for real-time control tasks?
The TMS570LS0714PZ integrates an ARM Cortex-R4F 32-bit RISC processor with a hardware single-precision floating-point unit, clocked at up to 80 MHz. The Cortex-R4F architecture is designed for hard real-time control, offering deterministic interrupt latency typically below 12 clock cycles (150 ns at 80 MHz) and zero-wait-state Flash execution, making it well-suited for closed-loop motor control, PID loops, and safety supervisors that must respond to events faster than 1 µs.
How does the lockstep CPU design in TMS570LS0714PZ support ISO 26262 functional safety certification?
The TMS570LS0714PZ uses a dual-core lockstep architecture where two Cortex-R4F cores execute the same instruction stream in parallel; a comparator checks both outputs every cycle and flags any mismatch as a CPU error within 1 clock cycle. This hardware diagnostic mechanism achieves a CPU fault-detection coverage above 99%, satisfying the hardware diagnostic coverage requirements for ASIL D under ISO 26262 and SIL 3 under IEC 61508, without requiring redundant software or external watchdog ICs for CPU-level faults.
Does TMS570LS0714PZ include on-chip analog peripherals, and which sensor types can it directly interface?
Yes. The TMS570LS0714PZ includes an on-chip 12-bit ADC with multiple input channels, a DAC output, and a DMA controller that transfers ADC conversion results to memory without CPU intervention. The ADC can directly accept signals from resistive temperature sensors, hall-effect current sensors, and potentiometers within the 0 V to 3.3 V input range, eliminating the need for external ADC ICs in moderate-accuracy (12-bit, approximately 0.8 mV resolution at 3.3 V) measurement applications.
What does JTAG boundary scan support in TMS570LS0714PZ enable during manufacturing test?
JTAG boundary scan (IEEE 1149.1) on the TMS570LS0714PZ allows automated board-level testing of all digital I/O pin interconnections without powering up the MCU's core logic. A boundary-scan chain connects all I/O cells, so a tester can drive signals out through one pin and capture them at another to verify solder joints, trace continuity, and short circuits in a populated PCB. This capability is mandatory for high-reliability assemblies in automotive and aerospace designs where 100% automated optical inspection alone is insufficient to detect all interconnect defects.
For a servo drive controller requiring sub-5 µs current-loop execution, is the TMS570LS0714PZ's 80 MHz clock adequate?
At 80 MHz, the TMS570LS0714PZ executes 80 million instructions per second, completing a typical 3-phase current-loop algorithm (Clarke/Park transforms, PID, SVPWM) in approximately 500 to 1500 clock cycles (6 µs to 19 µs) without FPU optimization. With the hardware floating-point unit reducing transform computation to 50–200 clock cycles and direct DMA feed of ADC results, the controller can achieve a 5 µs current-loop period for drives up to several tens of kilowatts, meeting the performance requirements of industrial servo and spindle motor drives.
