Product details
Overview
TMS320F28374DPTPS 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 HRPWM, 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 TMS320F28374DPTPS datasheet, TMS320F28374DPTPS pinout, TMS320F28374DPTPS application, or TMS320F28374DPTPS equivalent, key selection criteria include dual-CPU+CLA real-time partitioning, 169-pin HLQFP thermal performance, functional safety certification up to ASIL B/SIL 2, and support for isolated current sensing via SDFM + CMPSS.
Technical Context
The TMS320F28374DPTPS implements a tightly coupled dual-C28x architecture with interprocessor communication (IPC) and shared memory, enabling deterministic task splitting - e.g., one core handling torque/current loops while the other manages diagnostics and communications. Each CPU includes dedicated FPU, TMU, and VCU-II for fast trigonometric and complex math operations critical in motor vector control.
Its analog subsystem features four independent ADCs with hardware post-processing (offset calibration, windowed compare, trigger-to-sample capture), eight SDFM input channels with parallel filtering, and three 12-bit buffered DACs - all synchronized to PWM timers for closed-loop timing precision within ±1ns jitter tolerance in HRPWM mode.

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 |
|---|---|---|---|
| TMS320F28377DPTPS | 1MB flash (vs. 512KB), 204KB RAM (vs. 172KB), same 176-pin PTP package and peripherals | Higher memory capacity supports larger control algorithms, multi-axis motion profiles, or integrated communication stacks (e.g., CANopen + Ethernet gateway) | Select when firmware footprint exceeds 384KB or when dual-code security zones require additional protected memory allocation |
| TMS320F28375DPTPS | 100-pin HTQFP (PZP) package, reduced GPIO count (97), fewer ADC channels (20 vs. 24), no EMIF2 | Targeted at cost-sensitive, space-constrained applications like compact servo drives or HVAC fan controllers where full 169-pin I/O is unnecessary | Select when board area is constrained and peripheral count can be reduced - not a drop-in replacement due to package and pinout differences |
Compared with TMS320F28377DPTPS, the TMS320F28374DPTPS trades flash/RAM capacity for lower cost and optimized thermal dissipation in the 176-pin HLQFP; versus TMS320F28375DPTPS, it delivers full I/O scalability and dual EMIF support essential for high-channel-count power conversion systems.

FAQ
What is the maximum operating temperature range for the TMS320F28374DPTPS?
The TMS320F28374DPTPS is rated for a junction temperature range of –40°C to 105°C (T grade). This specification is validated per TI's recommended operating conditions and applies to the 176-pin HLQFP (PTP) package with proper PCB thermal design using the exposed PowerPAD™. Operation beyond 105°C requires derating per thermal resistance data in Section 6.7 of the SPRS880P datasheet.
Does the TMS320F28374DPTPS support functional safety certification out of the box?
Yes, the TMS320F28374DPTPS is ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD. It includes hardware safety mechanisms such as ECC on flash/RAM, windowed watchdog timers, missing-clock detection, and hardware BIST - documented in TI's functional safety manual SPRUI45. No additional silicon modifications are needed to meet these levels.
How many high-resolution PWM channels does the TMS320F28374DPTPS support?
The TMS320F28374DPTPS supports 16 high-resolution PWM (HRPWM) channels across 8 ePWM modules, with resolution down to 150ps. These channels are available on both A and B outputs of each module and include dead-band generation, trip-zone protection, and synchronization with ADC start-of-conversion triggers - all configurable via registers in the ePWM subsystem.
Can the TMS320F28374DPTPS execute code independently on both C28x cores and CLAs simultaneously?
Yes, the TMS320F28374DPTPS supports fully independent execution: both C28x CPUs and both CLAs operate concurrently at 200MHz. Each CLA responds to peripheral interrupts (e.g., ADC EOC, ePWM TZ event) and runs its own code from dedicated CLA RAM or L0/L1 program memory - with no dependency on CPU scheduling or shared instruction fetch bottlenecks.
What analog-to-digital converter configurations are supported by the TMS320F28374DPTPS?
The TMS320F28374DPTPS integrates four independent ADC modules (A/B/C/D), each configurable in 16-bit differential mode (1.1MSPS, 12 channels) or 12-bit single-ended mode (3.5MSPS, 24 channels). All ADCs feature hardware post-processing including saturating offset calibration, setpoint error calculation, and eight windowed comparators with 12-bit DAC references - accessible without CPU intervention.
