Product details
Overview
TMS320F28067UPZPS from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and VCU, designed for high-precision motor control and digital power conversion. It delivers 11.11-ns instruction cycle time, 128KB flash, 50KB RAM, 16-channel 12-bit ADC at 3.46 MSPS, and 16 ePWM channels (8 HRPWM-capable), targeting inverter gate drive and closed-loop servo execution.
For engineers reviewing the TMS320F28067UPZPS datasheet, TMS320F28067UPZPS pinout, TMS320F28067UPZPS application, or TMS320F28067UPZPS equivalent, key selection criteria include HRPWM dual-edge modulation support, on-chip temperature sensor, 3 analog comparators with DACs, USB 2.0 device/host capability, and AEC-Q100 qualification for automotive-grade thermal operation (–40°C to 125°C).
Technical Context
The TMS320F28067UPZPS implements a Harvard bus architecture with atomic instruction execution and unified memory mapping, enabling deterministic real-time response. Its C28x CPU executes native single-precision floating-point operations via dedicated FPU, while the independent CLA accelerates control law computation without CPU intervention.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO referencing, ePWM modules supporting frequency-modulated dual-edge control, and trip-zone protection routed directly from analog comparators. The device uses internal voltage regulation for single 3.3-V rail operation and supports IEEE 1149.1 JTAG boundary scan.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | TMS320C28x @ 90 MHz (11.11-ns cycle time); enables sub-microsecond interrupt latency for fast current loop closure. |
| Floating-Point Unit | Native single-precision FPU; eliminates software emulation overhead for trigonometric and PID calculations in motor algorithms. |
| Programmable CLA | 32-bit floating-point math accelerator running independently of CPU; offloads real-time PWM update and observer computations. |

The TMS320F28067UPZPS features a TMS320C28x CPU core rated at 90 MHz, delivering an instruction cycle time of 11.11 ns. This frequency is fully supported across the specified operating temperature range of –40°C to 125°C and is validated under nominal 3.3-V supply conditions per TI's SPRS698J datasheet revision.
Does the TMS320F28067UPZPS include a hardware floating-point unit?
Yes, the TMS320F28067UPZPS integrates a native single-precision floating-point unit (FPU) that executes IEEE 754-compliant operations directly in hardware. This eliminates software-emulated FP overhead and accelerates motor control algorithms such as Park/Clarke transforms and PI regulators in the TMS320F28067UPZPS.
How many high-resolution PWM channels does the TMS320F28067UPZPS support?
The TMS320F28067UPZPS supports 8 high-resolution PWM (HRPWM) channels, distributed across its 8 ePWM modules. Each HRPWM channel provides sub-nanosecond resolution for leading/trailing edge adjustment-enabling precise timing control in resonant converter topologies like LLC and ZVS circuits.
Is the TMS320F28067UPZPS AEC-Q100 qualified?
Yes, the TMS320F28067UPZPS carries AEC-Q100 Grade 0 qualification (–40°C to 125°C), confirmed by its "Q" suffix and explicit listing in TI's device comparison table. This qualification validates reliability for automotive under-hood applications including EV on-board chargers and traction inverter auxiliary controllers.
What package type and thermal features does the TMS320F28067UPZPS use?
The TMS320F28067UPZPS uses a 100-pin HTQFP package with PowerPAD™ (PZP), featuring an exposed thermal pad measuring 14.0 mm × 14.0 mm. The pad must be soldered to the PCB ground plane with thermal vias-TI specifies this for junction-to-board thermal resistance of 10.5°C/W, critical for sustained 90-MHz operation in sealed enclosures.
