Texas Instruments TMS320F28377DPTPS

Overview

TMS320F28377DPTPS from Texas Instruments is a dual-core 32-bit real-time microcontroller with two 200MHz C28x CPUs, IEEE 754 FPU, TMU, VCU-II, and two independent 200MHz CLA coprocessors. It integrates four 16-/12-bit ADCs (up to 4.4MSPS system throughput), 24 ePWM channels (16 HRPWM), dual CAN, USB 2.0, and 169 GPIOs. It targets high-precision motor control in EV traction inverters and solar power converters.

For engineers reviewing the TMS320F28377DPTPS datasheet, TMS320F28377DPTPS pinout, TMS320F28377DPTPS application, or TMS320F28377DPTPS equivalent, key selection criteria include dual-CPU real-time partitioning, on-chip analog subsystem performance (ADC resolution, DAC count, SDFM), functional safety certification (ISO 26262 ASIL B), and thermal grade (–40°C to 105°C junction).

Technical Context

The TMS320F28377DPTPS implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II for trigonometric and complex math acceleration. Each core has its own CLA executing floating-point code concurrently, enabling parallel torque/speed loop execution and offloading time-critical control tasks.

Its analog subsystem includes four independent ADCs supporting both 16-bit (1.1MSPS, differential) and 12-bit (3.5MSPS, single-ended) modes, eight windowed comparators with 12-bit DAC references, three buffered 12-bit DAC outputs, and eight SDFM input channels for isolated current sensing - all synchronized to PWM triggers for deterministic timing.

FAQ

What is the maximum operating junction temperature for the TMS320F28377DPTPS?

The TMS320F28377DPTPS is rated for a junction temperature range of –40°C to 105°C, designated by the 'T' temperature grade. This specification is validated per TI's thermal resistance characteristics and supports continuous operation in demanding industrial motor drive and solar inverter environments without derating under typical PCB thermal design conditions.

Does the TMS320F28377DPTPS support functional safety certification for automotive use?

Yes, the TMS320F28377DPTPS is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD. Its hardware integrity meets ASIL B requirements, and TI provides functional safety documentation to aid system-level design for automotive applications - though the 'T' grade part is not AEC-Q100 qualified (that requires the 'Q1' variant).

How many ADC channels does the TMS320F28377DPTPS support in 16-bit differential mode?

The TMS320F28377DPTPS supports up to 12 external analog input channels in 16-bit differential mode across its four independent ADCs. Each ADC accepts six differential pairs (e.g., ADCINA0/1, ADCINA2/3), and all 12 channels can be sampled simultaneously with hardware synchronization to PWM events.

Can the TMS320F28377DPTPS execute code independently on both C28x cores and CLAs simultaneously?

Yes, the TMS320F28377DPTPS supports true concurrent execution: both C28x CPUs run at 200MHz with full instruction sets, and each has an associated CLA that operates independently at 200MHz, responding to peripheral interrupts (e.g., ADC end-of-conversion) without CPU involvement - enabling deterministic, low-latency control loop partitioning.

What package type and pin count does the TMS320F28377DPTPS use?

The TMS320F28377DPTPS uses the 176-pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP) package, designated by the 'PTP' suffix. It features exposed thermal pad for enhanced heat dissipation and supports full access to 169 GPIOs, dual CAN, USB, and all major analog and control peripherals in this封装.
