Product details
Overview
TMS320F28376SPZPT from Texas Instruments is a 32-bit floating-point real-time microcontroller with dual 200MHz C28x CPU and CLA coprocessor, IEEE 754 FPU, TMU, VCU-II, 1MB flash (ECC-protected), 164KB RAM (ECC/parity-protected), and integrated analog subsystem including four 16-/12-bit ADCs (up to 4.4MSPS total) for high-precision motor control in EV traction inverters.
For engineers reviewing the TMS320F28376SPZPT datasheet, TMS320F28376SPZPT pinout, TMS320F28376SPZPT application, or TMS320F28376SPZPT equivalent, key selection criteria include its single-CPU/CLA subsystem architecture, 176-pin HLQFP package with 97 GPIOs, functional safety certification up to ASIL B/SIL 2, and support for high-resolution PWM (16 HRPWM channels), SDFM, and dual CAN interfaces.
Technical Context
The TMS320F28376SPZPT implements a deterministic real-time control architecture centered on a 200MHz C28x CPU with hardware accelerators (FPU, TMU, VCU-II) and an independent 200MHz CLA coprocessor that executes time-critical control loops concurrently. Its dual-zone security module enables third-party code protection, while the boot ROM supports multiple peripheral-boot modes.
Analog signal acquisition is handled by four independent ADCs configurable in 16-bit (1.1MSPS each, differential inputs) or 12-bit (3.5MSPS each, single-ended inputs) mode, each with dedicated S/H and hardware post-processing (offset calibration, windowed comparators, DAC-referenced thresholds). The integrated SDFM provides isolated current sensing via sigma-delta modulators.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377SPZPT | Same 176-pin HLQFP package, identical peripherals, but includes dual C28x+CLA subsystems (vs. single in F28376S). | Enables asymmetric dual-core control (e.g., one CPU for motor control, one for communications/BMS), whereas F28376S targets cost-optimized single-subsystem designs. | Select F28377S when dual real-time processing domains are required; F28376S suffices for consolidated single-loop architectures. |
| TMS320F28375SPZPT | Same package, but reduced memory: 512KB flash and 132KB RAM; fewer GPIOs (97 vs. same count, but fewer accessible peripherals in smaller packages). | Targeted at entry-level servo drives or UPS where lower code footprint and reduced analog channel count are acceptable. | Choose F28375S for cost-sensitive applications with simpler control requirements; F28376S provides headroom for future feature expansion and larger safety-certified code bases. |
Compared with TMS320F28377SPZPT, the TMS320F28376SPZPT offers identical packaging and peripheral count but halves computational throughput by disabling one C28x+CLA subsystem-reducing cost while retaining full analog and control peripheral capability for single-domain real-time systems. Against TMS320F28375SPZPT, it adds 512KB flash and 32KB RAM for larger safety stacks and more complex control algorithms.

FAQ
What is the maximum operating junction temperature for the TMS320F28376SPZPT?
The TMS320F28376SPZPT is rated for a junction temperature range of –40°C to 125°C (S-grade), validated per TI's SPRS881K datasheet revision February 2024. This rating supports operation in demanding environments such as under-hood automotive power modules and industrial motor drives with elevated ambient temperatures. Thermal design must ensure the exposed PowerPAD™ on the 176-pin HLQFP package maintains adequate copper area and solder void control to meet this specification.
Does the TMS320F28376SPZPT support functional safety certification for automotive use?
Yes, the TMS320F28376SPZPT is ISO 26262 certified up to ASIL B and IEC 61508 certified up to SIL 2 by TÜV SÜD, as documented in TI's SPRS881K datasheet. It includes hardware safety features such as ECC on flash/RAM, windowed watchdog timers, missing-clock detection, and hardware BIST. While not AEC-Q100 qualified itself (the Q1 version is TMS320F28376SQPZPT), its safety architecture enables integration into ASIL B–compliant systems like EV on-board chargers and auxiliary inverters.
How many high-resolution PWM channels does the TMS320F28376SPZPT provide?
The TMS320F28376SPZPT provides 16 high-resolution PWM (HRPWM) channels - eight modules, each with A and B outputs - supporting sub-nanosecond resolution for precise timing control in SiC and GaN-based power converters. These operate alongside 24 standard ePWM channels, all with configurable dead-band, trip-zone, and event-triggered ADC start capabilities, as confirmed in the device comparison table of SPRS881K.
What analog-to-digital converter configurations are supported by the TMS320F28376SPZPT?
The TMS320F28376SPZPT integrates four independent ADCs configurable in either 16-bit mode (1.1MSPS each, differential inputs, up to 12 external channels) or 12-bit mode (3.5MSPS each, single-ended inputs, up to 24 external channels). Each ADC includes a dedicated sample-and-hold, hardware post-processing (offset calibration, windowed comparators), and trigger-to-sample delay capture - enabling simultaneous high-fidelity acquisition across voltage, current, and temperature sensors in real-time power control systems.
Is the TMS320F28376SPZPT pin-compatible with other devices in the F2837xS family?
Yes, the TMS320F28376SPZPT is pin-compatible with other 176-pin HLQFP (PTP) variants in the F2837xS family, including TMS320F28375SPZPT and TMS320F28377SPZPT, sharing identical mechanical dimensions, ball/pin map, and power/ground assignments. Peripheral accessibility (e.g., EMIF2, second CAN) may differ due to internal configuration, but PCB layout remains interchangeable - allowing scalable design reuse across performance tiers within the same package footprint.
