Product details
Overview
TMS320F28378DPTPS 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 176-pin HLQFP package - deployed in EV traction inverters and solar power optimizers.
For engineers reviewing the TMS320F28378DPTPS datasheet, TMS320F28378DPTPS pinout, TMS320F28378DPTPS application, or TMS320F28378DPTPS equivalent, key selection criteria include dual-CPU deterministic latency, CLA offload capability for torque-loop control, 16-bit ADC resolution with hardware post-processing, and functional safety certification up to ASIL B/SIL 2.
Technical Context
The TMS320F28378DPTPS implements a tightly coupled dual-C28x architecture where each CPU runs at 200MHz with dedicated FPU, TMU, and VCU-II - enabling simultaneous high-precision motor control and signal processing. Its two CLAs execute floating-point code independently, triggered by peripheral events such as PWM sync or ADC completion.
On-chip analog subsystem includes four ADCs configurable in 16-bit (1.1MSPS, differential) or 12-bit (3.5MSPS, single-ended) mode, each with integrated S/H and hardware-accelerated post-processing (offset calibration, windowed compare, DAC-referenced comparators). The 176-pin HLQFP package exposes all 169 GPIOs, dual EMIFs, and full peripheral set including USB, uPP, and dual CAN.
Key Specifications

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 |
|---|---|---|---|
| TMS320F28379DPTP | 1MB flash (vs. 1MB), 204KB RAM (vs. 204KB), identical peripherals and package - differs only in device ID and minor qualification status. | No functional difference; both rated for –40°C to 105°C industrial operation. | Select TMS320F28379DPTP if full 1MB flash utilization or TI's latest production revision is required. |
| TMS320F28377DPTP | 512KB flash (vs. 1MB), 172KB RAM (vs. 204KB), same dual-core, CLA, ADC, and PWM architecture - reduced memory footprint. | Suitable for cost-sensitive motor drives with smaller control algorithm footprints and no need for extensive data logging or dual-application partitioning. | Choose TMS320F28377DPTP when memory budget is constrained but full peripheral feature set (e.g., dual CAN, USB, 4 ADCs) remains essential. |
Compared with TMS320F28379DPTP, the TMS320F28378DPTPS offers identical performance and peripheral count but targets industrial rather than automotive qualification; versus TMS320F28377DPTP, it doubles on-chip flash while retaining full HRPWM and CLB capability - making it optimal for complex, safety-aware power conversion systems requiring firmware redundancy and field-upgradeability.
