Product details
Overview
TMS320F28376SZWTS from Texas Instruments is a 32-bit floating-point real-time microcontroller with dual 200MHz C28x CPU + CLA subsystems, IEEE 754 FPU, TMU, VCU-II, 1MB flash (ECC-protected), 164KB RAM (ECC/parity-protected), and integrated analog/control peripherals including four 16-/12-bit ADCs (up to 4.4MSPS), 24 ePWM channels (16 HRPWM), six eCAP, three eQEP, eight SDFM inputs, and two CAN modules - deployed in industrial motor drives and solar inverters.
For engineers reviewing the TMS320F28376SZWTS datasheet, TMS320F28376SZWTS pinout, TMS320F28376SZWTS application, or TMS320F28376SZWTS equivalent, key selection criteria include its nFBGA-337 package, –40°C to 125°C junction temperature rating, functional safety compliance (ISO 26262 ASIL B / IEC 61508 SIL 2), and support for high-precision closed-loop control in power conversion systems.
Technical Context
The TMS320F28376SZWTS implements a dual-subsystem architecture: one C28x CPU and one CLA coprocessor, both running at 200MHz and executing IEEE 754 single-precision floating-point instructions independently. The CLA offloads time-critical control tasks such as PWM update, ADC post-processing, and protection logic from the main CPU.
Its analog subsystem integrates four independent 16-/12-bit ADCs with differential/single-ended input modes, hardware-accelerated post-processing (offset calibration, windowed compare, DAC-referenced comparators), and three 12-bit buffered DAC outputs. The control peripherals include 16 high-resolution PWM channels (8 modules × A/B), dead-band generation, and sigma-delta filter modules supporting isolated shunt current sensing.
Key Specifications

| CLA Coprocessor | Independent 32-bit floating-point CLA @ 200MHz - enables parallel execution of control law updates without CPU intervention. |
| Flash Memory | 1MB (512KW) ECC-protected flash - supports secure firmware storage and robust field updates in safety-critical systems. |
| RAM | 164KB (82KW) ECC/parity-protected RAM - provides fault-tolerant data buffering for control variables and state observers. |
| ADC Performance | Four 16-bit ADCs @ 1.1MSPS each (4.4MSPS total) with differential inputs - enables simultaneous sampling of multiple voltage/current feedback signals. |
| PWM Resolution | 24 ePWM channels with 16 HRPWM channels (sub-nanosecond resolution) - achieves precise timing control for SiC/GaN gate drivers in high-frequency inverters. |
| Functional Safety | ISO 26262 ASIL B & IEC 61508 SIL 2 certified by TÜV SÜD - meets hardware integrity requirements for automotive and industrial safety subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377S | Same nFBGA-337 package, identical peripherals, but 512KB flash and 132KB RAM. | Targeted at cost-sensitive industrial drives where firmware footprint and runtime memory are constrained. | Select when full 1MB flash and 164KB RAM are not required; retains same safety certification and thermal rating. |
| TMS320F28379S | Same 1MB/164KB memory, adds second C28x-CPU+CLA subsystem (dual-core), larger package footprint. | Required for asymmetric multi-core architectures (e.g., one core for control, one for comms/AI inference). | Choose only if dual-CPU parallelism is needed; otherwise TMS320F28376SZWTS offers optimal cost/performance balance for single-subsystem designs. |
Compared with TMS320F28377S, TMS320F28376SZWTS provides higher memory capacity for complex control algorithms and extended diagnostics; compared with TMS320F28379S, it eliminates redundant CPU/CLA resources while retaining identical analog/peripheral capability and safety certification - making it ideal for single-subsystem, high-reliability power electronics.
