Product details
Overview
TMS320F28377DPTPT from Texas Instruments is a dual-core 32-bit real-time microcontroller featuring two 200MHz C28x CPUs, IEEE 754 single-precision 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 with 16 high-resolution outputs, dual CAN, USB 2.0, and 169 GPIOs - deployed in traction inverter motor control, solar string inverters, and EV charging station power modules.
For engineers reviewing the TMS320F28377DPTPT datasheet, TMS320F28377DPTPT pinout, TMS320F28377DPTPT application, or TMS320F28377DPTPT equivalent, key selection considerations include dual-CPU+CLA parallel processing capability, 512KB flash/ECC, 172KB RAM/parity, HLQFP-176 thermal performance, functional safety certification up to ASIL B/SIL 2, and support for isolated current sensing via SDFM + CMPSS.
Technical Context
The TMS320F28377DPTPT implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II - enabling simultaneous torque/speed loop execution and fast trigonometric/complex math. Its two CLAs operate independently at 200MHz, responding to peripheral triggers to offload time-critical control law execution from main CPUs.
On-chip analog subsystem includes four ADCs supporting concurrent 16-bit (1.1MSPS each) and 12-bit (3.5MSPS each) modes with differential/single-ended inputs, hardware post-processing (offset calibration, windowed compare, DAC-referenced comparators), and three 12-bit buffered DAC outputs. The SDFM provides eight input channels with configurable sigma-delta filtering for shunt-based current measurement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377D-ZWT | Same dual-core architecture, 512KB flash, 172KB RAM, but in 337-ball nFBGA (16mm × 16mm) package | Better thermal performance and higher pin count (169 GPIOs fully accessible); suited for space-constrained, high-channel-count designs | Select ZWT for PCB area optimization and maximum peripheral access; PTP preferred when thermal pad soldering and manual assembly are required |
| TMS320F28379D-PTP | 1MB flash (512KW), 204KB RAM (102KW), same dual-core/CLA/FPU/ADC/peripheral set, identical PTP package | Higher memory capacity enables complex safety monitors, dual-firmware redundancy, and extended data logging in ASIL-B systems | Choose F28379D-PTP when >512KB flash or >172KB RAM is needed for functional safety partitions or future firmware expansion |

FAQ
What is the maximum operating frequency of each CPU core in the TMS320F28377DPTPT?
Each C28x CPU core in the TMS320F28377DPTPT operates at 200MHz. This frequency is sustained across the full industrial temperature range (–40°C to 105°C) under specified 1.2V core supply conditions. The CLA coprocessors also run at 200MHz, enabling parallel real-time computation without contention for main CPU resources. All timing specifications in the datasheet assume this 200MHz operation.
Does the TMS320F28377DPTPT support functional safety certification for automotive applications?
Yes, the TMS320F28377DPTPT 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 safety documentation-including FMEDA, safety manuals, and diagnostic coverage analysis-is provided to support system-level compliance in automotive traction inverters and charging systems.
How many ADC channels does the TMS320F28377DPTPT support in 16-bit differential mode?
The TMS320F28377DPTPT supports up to 12 external differential input channels across its four independent 16-bit ADCs - three per ADC bank (ADCINA/B/C/D). Each ADC achieves 1.1MSPS in this mode, with hardware-accelerated post-processing including saturation, setpoint error, and windowed comparison with interrupt generation.
What package type and thermal features does the TMS320F28377DPTPT use?
The TMS320F28377DPTPT uses the 176-pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP) package, designated by the PTP suffix. It features an exposed thermal pad on the underside for direct PCB copper connection, enabling efficient heat transfer to internal ground planes and improving thermal resistance by up to 40% versus standard QFP packages.
Can the TMS320F28377DPTPT execute code from external memory?
Yes, the TMS320F28377DPTPT includes two External Memory Interfaces (EMIFs): EMIF1 supports ASRAM and SDRAM (16-/32-bit), and EMIF2 supports ASRAM (16-bit). These interfaces allow execution of code and storage of data in external memory, enabling larger firmware images, real-time oscilloscope buffers, or secure boot verification tables beyond on-chip flash limits.
