Texas Instruments TMS320F28062PZT

Overview

TMS320F28062PZT from Texas Instruments is a 90-MHz C28x-core real-time microcontroller with integrated FPU, CLA, and advanced motor control peripherals including 16 ePWM channels (8 HRPWM-capable), 3 eCAP modules, 4 HRCAP modules, 2 eQEP modules, and a 12-bit 3.46-MSPS ADC - deployed in industrial motor drives, solar inverters, and EV charging power stages.

For engineers reviewing the TMS320F28062PZT datasheet, TMS320F28062PZT pinout, TMS320F28062PZT application, or TMS320F28062PZT equivalent, key selection considerations include HRPWM dual-edge modulation capability, on-chip VCU for CRC/Viterbi acceleration, 54 GPIO with input filtering, USB 2.0 device/host support, and 128KB flash/50KB RAM memory configuration.

Technical Context

The TMS320F28062PZT implements a Harvard-architecture C28x CPU with atomic instructions and unified memory mapping, paired with a dedicated 32-bit floating-point CLA that executes control law code independently of the main CPU. Its peripheral set is optimized for closed-loop timing-critical applications, featuring ePWM modules with trip-zone protection and direct comparator-to-PWM routing.

It integrates a Viterbi/Complex Math/CRC Unit (VCU) extending the C28x ISA for real-time signal integrity checks and complex arithmetic, alongside dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO references and configurable SOC-based triggering - all operating from a single 3.3-V supply with internal voltage regulation.

Key Specifications

Pinout & Package

The TMS320F28062PZT uses a 100-pin Low-Profile Quad Flatpack (LQFP) package designated PZ, with 14.0 mm × 14.0 mm body size and exposed thermal pad (non-electrical ground connection requiring PCB ground plane soldering).

Equivalent & Alternatives

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

Compared with TMS320F28069PZT, the TMS320F28062PZT offers identical CPU/CLA/VCU architecture and pin compatibility but reduces flash to 128KB and omits USB PHY - making it optimal for cost-sensitive, non-connectivity-focused motor control. The TMS320F280049CPZT delivers generational improvements in speed and analog performance but requires firmware migration due to CLB integration and absence of VCU.

FAQ

What is the maximum operating frequency of the TMS320F28062PZT?

The TMS320F28062PZT operates at a maximum CPU frequency of 90 MHz, corresponding to an instruction cycle time of 11.11 ns. This speed is sustained across its full temperature range (–40°C to 105°C) and is enabled by the C28x core's optimized pipeline and on-chip PLL. All timing-critical peripherals - including ePWM, ADC, and CLA - are fully synchronized to this clock domain in the TMS320F28062PZT.

Does the TMS320F28062PZT include a floating-point unit?

Yes, the TMS320F28062PZT integrates a native single-precision floating-point unit (FPU) as part of its C28x CPU core. This allows efficient execution of floating-point math in C/C++ without software emulation, significantly accelerating control law computation, trigonometric functions, and filter implementations. The FPU is fully supported in TI's C2000 compiler toolchain and works in concert with the CLA in the TMS320F28062PZT.

How many high-resolution PWM channels does the TMS320F28062PZT support?

The TMS320F28062PZT supports 8 high-resolution PWM (HRPWM) channels, distributed across its 8 ePWM modules. Each HRPWM channel provides sub-nanosecond resolution for fine edge placement - critical for minimizing dead-time distortion and improving efficiency in SiC/GaN-based inverters. These channels are accessible on dedicated EPWMxA/EPWMxB pins and are fully configurable via registers in the TMS320F28062PZT.

Is USB functionality available on the TMS320F28062PZT?

No, USB functionality is not available on the TMS320F28062PZT. While the broader F2806x family includes USB-enabled variants (e.g., TMS320F28062F), the TMS320F28062PZT omits the USB PHY and associated pins. This reflects its positioning as a cost-optimized variant for applications where serial, CAN, or SPI connectivity suffices - confirmed by TI's official device comparison table for the F2806x series.

What package type and thermal characteristics define the TMS320F28062PZT?

The TMS320F28062PZT uses a 100-pin Low-Profile Quad Flatpack (LQFP) package designated PZ, measuring 14.0 mm × 14.0 mm. It features an exposed thermal pad that must be soldered to the PCB ground plane - though electrically isolated from die VSS - to ensure reliable thermal dissipation under continuous 90-MHz operation. Its rated junction temperature range is –40°C to 105°C (T grade), validated per JEDEC JESD22-A108.
