Product details
Overview
TMS320F28378SPZPS from Texas Instruments is a 32-bit floating-point real-time microcontroller featuring a 200MHz C28x CPU, IEEE 754 FPU, Trigonometric Math Unit (TMU), and Viterbi/Complex Math Unit (VCU-II); includes one CLA coprocessor running at 200MHz, 1MB flash (ECC-protected), 164KB RAM (ECC/parity-protected), four 16-/12-bit ADCs (up to 4.4MSPS system throughput), and dual CAN modules - deployed in EV traction inverters and solar string inverters.
For engineers reviewing the TMS320F28378SPZPS datasheet, TMS320F28378SPZPS pinout, TMS320F28378SPZPS application, or TMS320F28378SPZPS equivalent, key selection criteria include CLA-enabled parallel control execution, ASIL B/SIL 2 functional safety certification, 169 GPIO with input filtering, HRPWM dead-band support, and nFBGA vs. QFP package compatibility for thermal and layout constraints.
Technical Context
The TMS320F28378SPZPS implements a single-CPU + single-CLA architecture (vs. dual-CPU F2837xD), enabling deterministic real-time control via concurrent C28x and CLA task execution - both at 200MHz with IEEE 754 FPU support. Its analog subsystem integrates four independent ADCs with hardware post-processing (offset calibration, windowed comparators, DAC-referenced thresholds) and eight SDFM channels for isolated shunt current sensing.
System-level timing relies on dual zero-pin 10MHz oscillators, on-chip crystal oscillator, and missing-clock detection; power architecture uses 1.2V core and 3.3V I/O rails. Peripheral interconnect employs data bus bridges for EMIF1/EMIF2, CAN-A/B (ISO 11898-1 compliant), USB 2.0 (MAC+PHY), and uPP interface for FPGA co-processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | C28x 32-bit floating-point processor at 200MHz - delivers deterministic real-time loop execution with FPU, TMU, and VCU-II acceleration for motor torque and digital power algorithms. |
| CLA Coprocessor | Single 32-bit floating-point CLA at 200MHz - executes time-critical control tasks (e.g., PWM update, protection logic) independently of main CPU, doubling effective computational throughput. |
| Flash / RAM | 1MB (512KW) ECC-protected flash; 164KB (82KW) RAM (ECC/parity-protected) - supports secure firmware storage, dual-zone code security, and robust runtime data integrity in industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28379S | Same 200MHz C28x+CLA architecture, but adds second CLA and larger memory (1MB flash, 164KB RAM); offered in ZWT nFBGA only. | Targeted at higher-complexity systems requiring dual-CLA parallelism (e.g., dual-motor drives) and larger code space for advanced diagnostics. | Select TMS320F28379S when dual-CLA concurrency or nFBGA thermal performance outweighs QFP layout simplicity and cost. |
| TMS320F28377S | Identical CPU/CLA specs and peripherals, but reduced memory: 512KB flash and 132KB RAM; available in PTP (176-pin) and PZP (100-pin) packages. | Suitable for cost-sensitive, lower-code-footprint applications like HVAC fan controllers or entry-level BLDC drives where full 1MB flash is unused. | Choose TMS320F28377S when design fits within 512KB flash and benefits from identical peripheral set with smaller footprint or lower BOM cost. |
Compared with TMS320F28379S, the TMS320F28378SPZPS offers identical real-time control capability and safety certification but trades dual-CLA for QFP package flexibility and full 1MB flash; versus TMS320F28377S, it provides 32KB more RAM and 512KB more flash while retaining pin compatibility in PTP package - making it optimal for mid-tier industrial inverters needing memory headroom without nFBGA assembly complexity.
