Product details
Overview
TMS320F28376SPZPS 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), three 12-bit DACs, and 24 ePWM channels - deployed in solar inverters, EV traction inverters, and industrial motor drives.
For engineers reviewing the TMS320F28376SPZPS datasheet, TMS320F28376SPZPS pinout, TMS320F28376SPZPS application, or TMS320F28376SPZPS equivalent, key selection criteria include its S-grade (–40°C to 125°C junction), nFBGA-337 package, CLA-accelerated closed-loop control capability, functional safety compliance (ISO 26262 ASIL B, IEC 61508 SIL 2), and support for high-resolution PWM, sigma-delta current sensing, and dual EMIF interfaces.
Technical Context
The TMS320F28376SPZPS implements a dual-subsystem architecture: one C28x CPU core and one independent CLA coprocessor, both operating at 200MHz with IEEE 754 single-precision floating-point execution. It integrates hardware accelerators - TMU for trigonometric functions and VCU-II for complex math - enabling deterministic execution of motor control torque loops and field-oriented control algorithms.
Its analog subsystem includes four independent 16-/12-bit ADCs with differential/single-ended input modes, hardware post-processing (offset calibration, windowed compare, error-from-setpoint), eight SDFM channels for isolated shunt current measurement, and a comparator subsystem with eight windowed comparators and internal 12-bit DAC references - all synchronized to PWM timing for precise power stage protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C28x 32-bit floating-point processor at 200MHz - delivers deterministic real-time control with cycle-accurate instruction timing for motor phase current sampling and PWM update. |
| CLA Coprocessor | Independent 32-bit floating-point accelerator at 200MHz - offloads time-critical control tasks (e.g., PID loops, observer calculations) from main CPU to enable parallel processing. |
| Flash Memory | 1MB (512KW) of ECC-protected on-chip flash - supports dual-zone security, bootloader partitioning, and robust firmware updates in safety-critical power electronics. |
| ADC System | Four 16-bit/12-bit ADCs: 1.1MSPS (16-bit) or 3.5MSPS (12-bit) per converter; up to 4.4MSPS / 14MSPS system throughput - enables simultaneous sampling of multiple voltage/current sensors in multi-phase inverters. |
| ePWM Channels | 24 enhanced PWM outputs with 16 high-resolution (HRPWM) channels - provides sub-nanosecond dead-time control and phase-shifted modulation for SiC/GaN gate drivers. |
| Functional Safety | ISO 26262 ASIL B and IEC 61508 SIL 2 certified by TÜV SÜD - includes HWBIST, memory ECC, clock monitoring, and watchdog timers for automotive and industrial safety systems. |
| Package & Temp | 337-ball nFBGA (ZWT suffix), 16mm × 16mm body; rated for –40°C to 125°C junction temperature - suitable for high-power density, thermally constrained applications like on-board chargers and string inverters. |
Pinout & Package
Package: 337-ball New Fine Pitch Ball Grid Array (nFBGA), 16mm × 16mm body size, lead-free/green compliant, ZWT suffix. Thermal pad on underside for enhanced heat dissipation in high-current motor control applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VDDA, VDDIO | Power supply rails | 1.2V core, 3.3V analog (VDDA), 3.3V I/O (VDDIO) - require separate low-noise LDOs and decoupling to maintain ADC accuracy and PWM timing integrity. |
| VSS, VSSA, VSSOSC | Ground planes | Dedicated analog ground (VSSA), oscillator ground (VSSOSC), and digital ground (VSS) - must be connected with low-inductance paths to minimize noise coupling into sensitive analog peripherals. |
| X1, X2 | Crystal oscillator inputs | Supports external crystal (e.g., 20MHz) for precise clock generation; internal 10MHz zero-pin oscillators provide fallback timing during crystal startup or failure. |
| GPIO0–GPIO169 | Multiplexed general-purpose I/O | 169 pins with programmable pullup/pulldown, input filtering, and peripheral muxing - enable flexible interface to encoders, Hall sensors, CAN transceivers, and external FPGA via uPP. |
| ADCINA0–ADCIND5 | Analog input channels | 24 dedicated ADC input pins supporting differential (12-channel) or single-ended (24-channel) acquisition - routed to four independent ADC modules with shared sample-and-hold. |
| ePWMxA/ePWMxB | PWM output pairs | 24 ePWM outputs organized as 12 A/B channel pairs with dead-band generation - each pair supports complementary high-resolution (HRPWM) outputs for half-bridge gate drive control. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Control Law Accelerator (CLA) | Offloads real-time control computations (e.g., FOC inner loop) from main CPU - reduces latency and increases system responsiveness without increasing core clock load. |

| Sigma-Delta Filter Module (SDFM) | Eight input channels with two parallel filters per channel - enables direct interface to isolated ΣΔ modulators (e.g., AMC1306) for high-accuracy, noise-immune current sensing in shunt-based designs. |
| Comparator Subsystem (CMPSS) | Eight windowed comparators with 12-bit DAC references - provides hardware-level overcurrent/undervoltage protection with <100ns response time, independent of CPU execution. |
| Dual External Memory Interface (EMIF) | EMIF1 (16/32-bit) + EMIF2 (16-bit) supporting ASRAM/SDRAM - allows expansion of program code or data buffers for advanced grid-synchronization algorithms and harmonic compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28377SPZPS | Same package and pinout; 1MB flash, 164KB RAM, but includes second C28x+CLA subsystem enabled - higher computational headroom for dual-inverter or sensor-fusion architectures. | Supports dual independent control loops (e.g., motor + PFC) or redundant safety monitoring - not required for single-loop applications. | Select when future scalability or functional safety redundancy is needed; otherwise TMS320F28376SPZPS offers optimal cost/performance for single-axis control. |
| TMS320F28375SPZPS | Same package; reduced memory: 512KB flash, 132KB RAM; fewer peripherals - only two ADCs, no EMIF2, 15 ePWM channels. | Suitable for cost-sensitive, lower-complexity applications such as single-phase inverters or fan motor drives with basic protection. | Choose for simplified BOM and lower thermal footprint where full ADC count, dual EMIF, or HRPWM density is unnecessary. |
Compared with TMS320F28377SPZPS, the TMS320F28376SPZPS delivers identical peripheral integration and safety certification at lower cost by disabling the second control subsystem; versus TMS320F28375SPZPS, it adds 512KB flash, 32KB RAM, dual EMIF, and eight additional ePWM channels - enabling more sophisticated grid-support features and faster firmware development cycles.
