Texas Instruments TMS320F28076PTPS

Overview

TMS320F28076PTPS from Texas Instruments is a 120MHz C28x 32-bit floating-point real-time microcontroller with IEEE 754 FPU, Trigonometric Math Unit (TMU), and independent 120MHz Control Law Accelerator (CLA). It integrates 512KB ECC-protected flash, 100KB RAM (ECC/parity), three 12-bit ADCs (3.1MSPS each), 24 ePWM channels (16 HRPWM), dual CAN, USB 2.0, and CLB for industrial motor control and solar inverter applications.

For engineers reviewing the TMS320F28076PTPS datasheet, TMS320F28076PTPS pinout, TMS320F28076PTPS application, or TMS320F28076PTPS equivalent, key selection criteria include HRPWM resolution for SiC/GaN gate drive timing, CLA offloading capability for torque-loop computation, ADC simultaneous sampling across three power phases, functional safety certification up to ASIL B/SIL 2, and thermal performance of the 176-pin HLQFP PowerPAD package.

Technical Context

The TMS320F28076PTPS implements a dual-core real-time architecture: the C28x CPU handles system-level tasks and communications, while the CLA executes time-critical control loops-such as field-oriented control (FOC) or sensorless estimation-concurrently and independently. Its analog subsystem supports synchronized sampling across three 12-bit ADCs with hardware post-processing including windowed comparators, DAC-referenced trip generation, and error-from-setpoint calculation.

Peripherals are tightly coupled via dedicated data bus bridges: ePWM modules feature dead-band insertion and TZ fault inputs tied directly to comparator outputs; SDFM channels interface with isolated ΣΔ modulators for current sensing; and dual CAN modules comply with ISO 11898-1/CAN 2.0B with 32-message mailboxes. The device operates from a 3.3V I/O supply with internal 1.2V core regulation and supports multiple low-power modes with external wakeup.

FAQ

What is the operating temperature range for the TMS320F28076PTPS?

The TMS320F28076PTPS is rated for –40°C to 105°C junction temperature (TJ), denoted by the 'T' suffix. This industrial-grade rating ensures reliable operation in demanding environments such as motor drive cabinets and outdoor solar inverters without derating under typical thermal design conditions.

Does the TMS320F28076PTPS support functional safety certification?

Yes, the TMS320F28076PTPS is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. It includes hardware safety mechanisms such as ECC memory, HWBIST, lockstep-capable peripherals, and diagnostic libraries to support system-level compliance in automotive and industrial safety applications.

How many high-resolution PWM channels does the TMS320F28076PTPS provide?

The TMS320F28076PTPS provides 16 high-resolution PWM (HRPWM) channels-eight modules with A/B output pairs-enabling <150ps duty-cycle resolution. This capability is essential for precise gate timing in SiC and GaN-based power stages used in high-efficiency OBC and PCS designs.

Can the TMS320F28076PTPS execute code independently on both CPU and CLA cores?

Yes, the TMS320F28076PTPS features a fully autonomous Control Law Accelerator (CLA) that runs IEEE 754 floating-point code concurrently with the main C28x CPU. The CLA responds to peripheral triggers (e.g., ADC end-of-conversion or ePWM timer overflow) and accesses shared memory without CPU intervention.

What analog inputs are supported by the TMS320F28076PTPS for three-phase motor control?

The TMS320F28076PTPS supports up to 17 external analog inputs across three independent 12-bit ADCs, enabling simultaneous sampling of phase currents, DC-link voltage, and temperature sensors. Dedicated ADCINx pins (e.g., ADCINA0–5, ADCINB0–5, ADCIN14–15) allow flexible routing for shunt- or isolated-sensing topologies.
