Product details
Overview
TMS320F28377SPTPQ from Texas Instruments is a 32-bit floating-point real-time microcontroller with dual-core architecture (C28x CPU + CLA coprocessor), 200MHz operation, IEEE 754 FPU, TMU/VCU-II accelerators, 1MB flash, and 164KB RAM. It integrates four 16-bit ADCs (1.1MSPS each), 24 ePWM channels (16 HRPWM), dual CAN, USB 2.0, and SDFM for isolated current sensing-targeted at high-precision motor control in EV traction inverters and solar power converters.
For engineers reviewing the TMS320F28377SPTPQ datasheet, TMS320F28377SPTPQ pinout, TMS320F28377SPTPQ application, or TMS320F28377SPTPQ equivalent, key selection criteria include its single-CPU/CLA subsystem configuration (vs. dual-CPU F2837xD), -40°C to 125°C junction temperature rating, HLQFP-176 package with PowerPAD thermal enhancement, and functional safety compliance up to ASIL B/SIL 2.
Technical Context
The TMS320F28377SPTPQ implements a deterministic real-time control architecture where the C28x CPU and independent CLA coprocessor both run at 200MHz, enabling parallel execution of main control loops and time-critical peripheral servicing. Its analog subsystem includes four synchronized 16-bit ADCs with differential inputs, hardware post-processing (windowed comparators, DAC-referenced thresholds), and SDFM for sigma-delta modulator interfacing.
System-level integration is enhanced by dual EMIFs supporting ASRAM/SDRAM, six-channel DMA, 169 GPIOs with input filtering, and communications peripherals including two ISO 11898-1 CAN modules, three SPI ports, four SCI/UARTs, two I²C interfaces, and a uPP interface for FPGA co-processing-all operating under 1.2V core / 3.3V I/O voltage domains.

FAQ
What is the maximum operating frequency of the TMS320F28377SPTPQ CPU and CLA?
The TMS320F28377SPTPQ features a C28x CPU and a Control Law Accelerator (CLA) both operating at 200MHz. This dual-processor architecture enables concurrent execution of main control algorithms on the CPU and time-critical tasks (e.g., PWM update, fault response) on the CLA-effectively doubling real-time throughput without increasing clock domain complexity. The 200MHz rating is guaranteed across the full –40°C to +125°C junction temperature range.
Does the TMS320F28377SPTPQ support functional safety certification for industrial applications?
Yes, the TMS320F28377SPTPQ is developed for functional safety applications and certified to IEC 61508 up to SIL 2 and ISO 26262 up to ASIL B by TÜV SÜD. It includes hardware features such as Error Correction Code (ECC) on flash and RAM, Hardware Built-in Self Test (HWBIST), windowed watchdog timers, and memory protection units-enabling system-level compliance in industrial motor drives and energy storage power conversion systems.
How many ADC modules does the TMS320F28377SPTPQ integrate, and what are their key specifications?
The TMS320F28377SPTPQ integrates four independent 16-bit analog-to-digital converters. Each operates at up to 1.1MSPS in 16-bit mode (4.4MSPS total system throughput), supports differential inputs, and provides up to 12 external channels. They include hardware post-processing features such as saturating offset calibration, setpoint error calculation, and eight windowed comparators with 12-bit DAC references-reducing software overhead in protection and control loops.
What package type and thermal characteristics define the TMS320F28377SPTPQ?
The TMS320F28377SPTPQ uses a 176-pin PowerPAD™ Thermally Enhanced Low-Profile Quad Flatpack (HLQFP, PTP suffix), with a 26mm × 26mm body and exposed thermal pad. Its thermal resistance (θJA) is 21.2°C/W, and it is rated for –40°C to +125°C junction temperature (S-grade). The PowerPAD design enables efficient heat transfer to the PCB, critical for sustained operation in high-power motor control and power conversion applications.
Can the TMS320F28377SPTPQ be used as a direct replacement for the TMS320F28379S in existing designs?
No-the TMS320F28377SPTPQ is not a direct replacement for the TMS320F28379S. While both share the same PTP package and pinout, the F28379S includes dual C28x CPU + CLA subsystems (2×200MHz), whereas the F28377S has only one. Additionally, the F28379S offers 169 GPIOs and full peripheral complement, while the F28377S in PTP package supports only 97 GPIOs due to pin count limitations. System-level revalidation is required.
