Texas Instruments TMS320F28067PZT

Overview

TMS320F28067PZT 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 industrial inverters and EV charging modules.

For engineers reviewing the TMS320F28067PZT datasheet, TMS320F28067PZT pinout, TMS320F28067PZT application, or TMS320F28067PZT equivalent, key selection factors include ePWM channel count (16), HRPWM capability (8 channels), on-chip flash (64 KB), RAM (50 KB), and 100-pin LQFP thermal performance at –40°C to 105°C.

Technical Context

The TMS320F28067PZT implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory mapping, enabling deterministic real-time control. Its dual 16-bit ePWM timers per module support independent frequency/phase modulation, while the CLA offloads floating-point math for sensorless FOC algorithms without CPU intervention.

Peripheral integration includes three eCAP modules for precise edge timing, four HRCAP units for sub-nanosecond capture resolution, and dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO references-enabling simultaneous sampling of current/voltage feedback in three-phase motor drives.

FAQ

What is the maximum operating frequency and instruction cycle time of the TMS320F28067PZT?

The TMS320F28067PZT operates at a maximum CPU frequency of 90 MHz, delivering an instruction cycle time of 11.11 ns. This timing is guaranteed across the full –40°C to 105°C temperature range and 3.3-V ±5% supply, enabling deterministic execution of real-time control loops with sub-microsecond jitter.

Does the TMS320F28067PZT include a floating-point unit and hardware math accelerator?

Yes, the TMS320F28067PZT integrates a native single-precision floating-point unit (FPU) and a programmable Control Law Accelerator (CLA). The CLA executes floating-point control code independently of the main C28x CPU, allowing concurrent execution of current regulation and position estimation loops in motor control applications.

How much on-chip memory does the TMS320F28067PZT provide, and what types are available?

The TMS320F28067PZT provides 64 KB of on-chip flash memory (organized in eight 8-KB sectors), 50 KB of RAM (34 KB SARAM + 16 KB DPSARAM), and 1 KB of one-time programmable (OTP) ROM. All memory blocks support code security via the CSM module to prevent unauthorized access or reverse engineering.

What ADC performance specifications does the TMS320F28067PZT support?

The TMS320F28067PZT features a 12-bit analog-to-digital converter with dual sample-and-hold capability, achieving up to 3.46 million samples per second (MSPS) and supporting up to 16 input channels. Conversion time is 289 ns, and the ADC accepts ratio-metric references (VREFHI/VREFLO) for robust operation under varying supply conditions.

Is the TMS320F28067PZT pin-compatible with other devices in the F2806x family?

The TMS320F28067PZT shares the same 100-pin LQFP (PZ) package footprint and pinout with TMS320F28069PZT and TMS320F28068PZT, enabling direct substitution where flash/RAM requirements align. However, it is not pin-compatible with 80-pin variants (PN/PFP) or devices lacking USB or VCU functionality due to differing peripheral mappings.
