Product details
Overview
TMS320F28378SPTPS from Texas Instruments is a 32-bit floating-point real-time microcontroller with a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II), integrated into a single 176-pin HLQFP package rated for –40°C to 125°C junction operation. It delivers deterministic control for high-precision motor drives and digital power conversion.
For engineers reviewing the TMS320F28378SPTPS datasheet, TMS320F28378SPTPS pinout, TMS320F28378SPTPS application, or TMS320F28378SPTPS equivalent, key selection considerations include its dual 16-bit/12-bit ADC subsystem (1.1MSPS/3.5MSPS), 24 ePWM channels with 16 HRPWM outputs, CLA coprocessor running at 200MHz, and ISO 11898-1 CAN compliance - all validated for industrial and EV charging power modules.
Technical Context
The TMS320F28378SPTPS implements a single-CPU, single-CLA architecture derived from the F2837xS family, enabling parallel execution of time-critical control loops on the CLA while the main C28x CPU handles communications and diagnostics. Its analog subsystem integrates four independent 16-/12-bit ADCs with hardware post-processing including windowed comparators and DAC references.
System-level timing is managed by two internal zero-pin 10MHz oscillators, an on-chip crystal oscillator, and a windowed watchdog timer. The device supports dual-zone security, ECC-protected flash (1MB), and parity/ECC-protected RAM (164KB), with functional safety documentation aligned to ISO 26262 ASIL B and IEC 61508 SIL 2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377SPTPS | Same package and pinout; reduced memory (512KB flash, 132KB RAM) and fewer peripherals (2 ADCs, 15 ePWMs, 2 CANs). | Targeted at cost-sensitive, lower-channel-count motor drives where full F28378S capability is unused. | Select when system complexity allows reduction in ADC count, PWM channels, and memory footprint without sacrificing thermal rating (–40°C to 125°C). |
| TMS320F28379SZWT | 337-ball nFBGA package; adds second C28x+CLA subsystem, 169 GPIOs, EMIF2, and full peripheral complement. | Required for ultra-high-performance applications needing dual-core deterministic control or external SDRAM interfacing. | Choose only if dual-CLA parallelism, expanded memory bandwidth, or additional GPIOs justify PCB redesign and thermal management changes. |
Compared with TMS320F28377SPTPS, the TMS320F28378SPTPS provides 100% more flash, 24% more RAM, double the ADC count, and 60% more ePWM channels - making it optimal for full-featured traction inverters and bidirectional EV chargers. Versus TMS320F28379SZWT, it trades dual-CLA scalability for HLQFP manufacturability and thermal performance in constrained form factors.

FAQ
What is the maximum operating junction temperature for the TMS320F28378SPTPS?
The TMS320F28378SPTPS is rated for a junction temperature range of –40°C to 125°C, as confirmed by TI's SPRS881K datasheet revision February 2024. This S-temperature grade enables deployment in under-hood automotive power modules and industrial enclosures without forced air cooling, provided PCB thermal design meets TI's recommended copper pour and via guidelines for the HLQFP PowerPAD package.
Does the TMS320F28378SPTPS support CAN FD or only classical CAN 2.0B?
The TMS320F28378SPTPS integrates two D_CAN modules compliant with ISO 11898-1, supporting only Classical CAN 2.0B (up to 1 Mbps), not CAN FD. Its CAN controllers lack the extended data length and bit rate switching features required for CAN FD. For CAN FD applications, TI recommends the TMS320F2838x series or external CAN FD transceivers with protocol translation.
How many high-resolution PWM (HRPWM) channels does the TMS320F28378SPTPS provide?
The TMS320F28378SPTPS provides 16 HRPWM channels - eight modules, each with high-resolution capability on both A and B outputs. This is explicitly documented in the Device Comparison table (Table 4-1) of SPRS881K, confirming full HRPWM support across all ePWM modules in the 176-pin PTP variant.
Is the TMS320F28378SPTPS pin-compatible with the TMS320F28377SPTPS?
Yes, the TMS320F28378SPTPS and TMS320F28377SPTPS share identical 176-pin HLQFP (PTP) packaging and pinout, as verified in TI's Package Information tables and Device Comparison section. Both devices use the same mechanical footprint, signal assignments, and power/ground ball layout, enabling drop-in replacement where peripheral and memory requirements align.
What analog-to-digital converter (ADC) configurations are supported by the TMS320F28378SPTPS?
The TMS320F28378SPTPS supports four independent ADCs configurable in either 16-bit mode (1.1MSPS, differential inputs, up to 12 external channels) or 12-bit mode (3.5MSPS, single-ended inputs, up to 24 external channels). Each ADC includes a dedicated Sample-and-Hold and hardware post-processing engine with offset calibration and windowed compare functions - all confirmed in Section 1 Features and Table 4-1 of SPRS881K.
