Texas Instruments TMS320F28067PZPQ

Overview

TMS320F28067PZPQ from Texas Instruments is a 90-MHz C28x-core 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-qualified systems. It delivers 11.11-ns instruction cycle time, 16 ePWM channels (8 HRPWM-capable), 3 eCAP modules, 2 eQEP interfaces, and 54 GPIOs in a 100-pin HTQFP PowerPAD package.

For engineers reviewing the TMS320F28067PZPQ datasheet, TMS320F28067PZPQ pinout, TMS320F28067PZPQ application, or TMS320F28067PZPQ equivalent, key selection criteria include AEC Q100 qualification (–40°C to 125°C), on-chip security (128-bit key), dual-sample-and-hold ADC, and hardware-accelerated control law execution via CLA.

Technical Context

The TMS320F28067PZPQ implements a Harvard architecture C28x CPU with atomic operations and unified memory programming, coupled to a dedicated 32-bit floating-point CLA that executes control algorithms independently of the main CPU. Its VCU extends instruction set support for complex math, CRC, and Viterbi operations.

Peripheral integration includes 8 ePWM modules with dual-edge modulation capability, analog comparators routed directly to ePWM trip zones, and a 12-bit ADC with ratio-metric reference support (VREFHI/VREFLO) and DMA-accessible result registers - all optimized for low-latency, high-fidelity real-time feedback loops.

FAQ

What is the operating temperature range and automotive qualification status of the TMS320F28067PZPQ?

The TMS320F28067PZPQ is rated for –40°C to 125°C and is AEC Q100 qualified (Grade 0), making it suitable for under-hood automotive applications such as on-board chargers and traction inverters where thermal robustness and reliability are critical. This qualification covers stress testing for temperature cycling, humidity, and electrical performance across the full range.

Does the TMS320F28067PZPQ include a floating-point unit and hardware accelerator for control algorithms?

Yes, the TMS320F28067PZPQ integrates a native single-precision floating-point unit (FPU) and a programmable Control Law Accelerator (CLA) that executes 32-bit floating-point code independently of the C28x CPU. This enables parallel, deterministic execution of PID, FOC, or observer algorithms - reducing CPU load and improving loop timing predictability in the TMS320F28067PZPQ.

How many PWM channels does the TMS320F28067PZPQ support, and what is their resolution capability?

The TMS320F28067PZPQ supports 16 enhanced PWM (ePWM) channels across eight modules, with eight channels capable of high-resolution PWM (HRPWM) operation. HRPWM provides sub-nanosecond timing adjustment for precise dead-time control and adaptive modulation schemes - essential for minimizing switching losses in SiC/GaN-based power stages used with the TMS320F28067PZPQ.

What analog-to-digital conversion capability does the TMS320F28067PZPQ provide?

The TMS320F28067PZPQ features a 12-bit ADC with 3.46 MSPS maximum sampling rate and dual sample-and-hold circuitry, supporting up to 16 input channels. It includes ratio-metric reference support (VREFHI/VREFLO) and DMA-accessible result registers - enabling synchronized, low-latency acquisition for current sensing, voltage monitoring, and thermal feedback in real-time control loops implemented on the TMS320F28067PZPQ.

Is the TMS320F28067PZPQ pin-compatible with other devices in the F2806x family?

The TMS320F28067PZPQ shares the same 100-pin HTQFP PowerPAD (PZP) package and pinout with TMS320F28069PZPQ and TMS320F28068PZPQ, enabling hardware reuse across variants. However, differences in flash size (64 KB vs. 128 KB), VCU presence, and CLA availability require firmware validation when migrating - the TMS320F28067PZPQ is not a drop-in replacement for higher-feature variants without software review.
