Texas Instruments TMS320F28062UPZT

Overview

TMS320F28062UPZT 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 TMS320F28062UPZT datasheet, TMS320F28062UPZT pinout, TMS320F28062UPZT application, or TMS320F28062UPZT equivalent, this page delivers verified specifications, package mapping, peripheral roles, and validated alternative options for embedded motor drive design.

Technical Context

The TMS320F28062UPZT implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory model, paired with a dedicated 32-bit floating-point CLA that runs control law code independently of the main CPU. Its VCU extends instruction set support for complex math, CRC, and Viterbi operations.

It integrates dual-sample-and-hold ADC with 16 channels, three eQEP modules, eight ePWM modules (16 total channels, 8 HRPWM-capable), and analog comparators with internal 10-bit references routed directly to ePWM trip zones - all optimized for high-fidelity real-time current/voltage sensing and PWM modulation in power electronics.

FAQ

What is the maximum operating frequency of the TMS320F28062UPZT?

The TMS320F28062UPZT operates at a maximum CPU frequency of 90 MHz, corresponding to an instruction cycle time of 11.11 ns. This speed is sustained across the full –40°C to 105°C temperature range under 3.3-V supply conditions, as specified in the device's recommended operating conditions table. The TMS320F28062UPZT achieves this performance using an on-chip PLL with internal oscillators or external crystal input.

Does the TMS320F28062UPZT include a floating-point unit (FPU)?

Yes, the TMS320F28062UPZT includes a native single-precision floating-point unit (FPU) integrated into its C28x CPU core. This allows direct execution of IEEE 754-compliant floating-point arithmetic without software emulation, significantly accelerating C/C++-based control algorithms such as Park/Clarke transforms and adaptive observers. The FPU is fully supported by TI's C2000 compiler toolchain.

How many high-resolution PWM (HRPWM) channels does the TMS320F28062UPZT support?

The TMS320F28062UPZT supports 8 high-resolution PWM (HRPWM) channels, distributed across its 8 ePWM modules. Each HRPWM channel provides sub-nanosecond resolution for fine timing control - critical for SiC and GaN-based power stages. These channels are implemented within the same 16-channel ePWM resource pool and share the same trip-zone protection architecture as standard ePWM outputs.

What package type and thermal features does the TMS320F28062UPZT use?

The TMS320F28062UPZT uses a 100-pin HTQFP package with PowerPAD™ (PZP), measuring 14.0 mm × 14.0 mm. Its exposed thermal pad must be soldered to the PCB ground plane using an array of thermal vias to achieve optimal junction-to-board thermal resistance (θ_JB = 12.5°C/W). The PowerPAD is not electrically connected to internal VSS, so it serves only a thermal function unless explicitly grounded externally.

Is USB functionality available on the TMS320F28062UPZT?

Yes, the TMS320F28062UPZT includes a full-speed USB 2.0 peripheral supporting both device and host modes. Pins USB0DP and USB0DM are assigned to GPIO26 and GPIO27 respectively in the 100-pin PZP package. This interface enables firmware updates, real-time debug streaming, and host-side configuration without requiring external USB-to-UART bridges or JTAG probes.
