Texas Instruments TMS320F28067PFPQ

Overview

TMS320F28067PFPQ from Texas Instruments is a 90-MHz C28x-based real-time microcontroller with integrated FPU, CLA, and 12-bit 3.46-MSPS ADC, designed for closed-loop motor control and digital power conversion in automotive-grade (AEC Q100) applications. It delivers 11.11-ns instruction cycle time, 16 ePWM channels (8 HRPWM-capable), 3 eCAP modules, 2 eQEP modules, and 54 GPIO pins in an 80-pin HTQFP package.

For engineers reviewing the TMS320F28067PFPQ datasheet, TMS320F28067PFPQ pinout, TMS320F28067PFPQ application, or TMS320F28067PFPQ equivalent, key selection considerations include its AEC Q100 qualification, dual-edge HRPWM capability, on-chip VCU for CRC/Viterbi acceleration, 128KB flash/50KB RAM memory map, and USB 2.0 host/device support - all critical for EV charging, servo drives, and solar inverter designs requiring functional safety and deterministic timing.

Technical Context

The TMS320F28067PFPQ implements a Harvard-architecture C28x CPU with atomic instructions and unified memory model, paired with a dedicated 32-bit floating-point CLA that executes control law code independently of the main CPU. Its peripheral set includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO references and configurable analog comparators routed directly to ePWM trip zones.

System-level timing is managed via two zero-pin oscillators, PLL clock synthesis, and missing-clock detection, while power integrity is maintained by an internal voltage regulator enabling single 3.3-V rail operation without sequencing. The device supports IEEE 1149.1 JTAG boundary scan and real-time hardware debug with analysis breakpoints.

Key Specifications

Pinout & Package

80-pin HTQFP (PFP) PowerPAD™ thermally enhanced thin quad flatpack with exposed thermal pad (not electrically connected to VSS; must be soldered to PCB ground plane). Pin 19 multiplexes ADCINA0 and VREFHI (mutually exclusive); Pin 21 ties VREFLO to VSSA internally.

Equivalent & Alternatives

The following parts are listed as comparable options for similar real-time control applications.

Compared with TMS320F28069PFPQ, the TMS320F28067PFPQ omits VCU but retains identical CPU, CLA, ADC, and PWM performance - making it optimal for cost-sensitive motor control where CRC/Viterbi acceleration is unnecessary. Versus TMS320F280049CPTQ, it offers proven AEC Q100 qualification and simpler migration from legacy F2806x code, though with lower analog resolution and no CLB.

FAQ

What is the maximum operating frequency and instruction cycle time of the TMS320F28067PFPQ?

The TMS320F28067PFPQ operates at a maximum CPU frequency of 90 MHz, delivering an instruction cycle time of 11.11 nanoseconds. This timing is achieved using the on-chip PLL with either internal zero-pin oscillators or an external crystal (X1/X2) input, and is fully supported across its –40°C to 125°C automotive temperature range. The TMS320F28067PFPQ maintains this performance without requiring external clock conditioning circuitry.

Does the TMS320F28067PFPQ include a floating-point unit and control law accelerator?

Yes, the TMS320F28067PFPQ integrates both a native single-precision floating-point unit (FPU) and a programmable Control Law Accelerator (CLA). The CLA is a separate 32-bit floating-point processor that runs control algorithms concurrently with the main C28x CPU, enabling deterministic execution of time-critical loops such as FOC current regulation without CPU intervention. This dual-core architecture is central to the TMS320F28067PFPQ's real-time control capability.

What analog-to-digital converter specifications does the TMS320F28067PFPQ support?

The TMS320F28067PFPQ features a 12-bit analog-to-digital converter with dual sample-and-hold, capable of up to 3.46 million samples per second (MSPS) and 289 ns conversion time. It supports 16 input channels (ADCINA0–7 and ADCINB0–7), ratio-metric VREFHI/VREFLO referencing, and direct routing to DMA for zero-CPU-overhead data acquisition. These specs make the TMS320F28067PFPQ suitable for high-fidelity current/voltage sensing in fast-switching power converters.

Is the TMS320F28067PFPQ AEC Q100 qualified, and what temperature range does it support?

Yes, the TMS320F28067PFPQ carries AEC Q100 qualification for automotive applications and is rated for operation from –40°C to +125°C. This qualification covers stress tests including ESD (HBM ±2 kV), latch-up (±100 mA), and gate oxide integrity. The "Q" suffix in TMS320F28067PFPQ explicitly denotes this automotive qualification, distinguishing it from commercial-grade variants like TMS320F28067PFP.

What communication interfaces are available on the TMS320F28067PFPQ?

The TMS320F28067PFPQ provides two SCI/UART modules, two SPI modules, one I²C bus, one enhanced CAN (eCAN) controller with 32 mailboxes, one multichannel buffered serial port (McBSP), and one full-speed USB 2.0 interface supporting device and host modes. All interfaces are DMA-accessible and support interrupt-driven operation. The eCAN and USB capabilities make the TMS320F28067PFPQ well-suited for networked motor drives and firmware-upgradable power systems.
