Product details
Overview
TMS320F28062UPNT 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 TMS320F28062UPNT datasheet, TMS320F28062UPNT pinout, TMS320F28062UPNT application, or TMS320F28062UPNT equivalent, key selection criteria include ePWM channel count (16), HRPWM capability (8 channels), on-chip flash (64 KB), RAM (34 KB), and USB 2.0 host/device support - all confirmed for this specific variant.
Technical Context
The TMS320F28062UPNT implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory mapping, paired with a dedicated 32-bit floating-point CLA that runs independently of the main core to offload real-time control loops. Its VCU extends instruction set support for CRC, Viterbi, and complex math operations.
Peripheral integration includes dual-sample-and-hold ADC with 16-channel input multiplexing, three eCAP modules, four HRCAP modules, two eQEP interfaces, and full-featured serial connectivity (2×SCI/UART, 2×SPI, I²C, eCAN, McBSP, USB 2.0), all accessible via DMA and PIE interrupt routing.

FAQ
What is the maximum operating frequency of the TMS320F28062UPNT?
The TMS320F28062UPNT operates at a maximum CPU frequency of 90 MHz, corresponding to an instruction cycle time of 11.11 ns. This speed is achieved using the C28x 32-bit core with on-chip PLL and supports deterministic real-time execution for motor control and digital power applications. The TMS320F28062UPNT maintains this performance across its full industrial temperature range (–40°C to 105°C).
Does the TMS320F28062UPNT include a floating-point unit (FPU)?
Yes, the TMS320F28062UPNT integrates a native single-precision floating-point unit (FPU) alongside its C28x CPU core. This FPU accelerates mathematical operations required for field-oriented control (FOC), sensorless estimation, and digital filter implementation - eliminating the need for fixed-point approximation and reducing development time. The TMS320F28062UPNT's FPU is fully IEEE 754-compliant and supported by TI's C2000 compiler toolchain.
How many ePWM channels does the TMS320F28062UPNT support, and are any HRPWM-capable?
The TMS320F28062UPNT supports 16 ePWM output channels across eight modules, with 8 of those channels designated as high-resolution PWM (HRPWM). These HRPWM channels deliver 150-ps resolution and support dual-edge control, enabling precise timing for SiC and GaN gate drivers in high-frequency power converters. This capability is confirmed for the TMS320F28062UPNT in the official device comparison table and functional block diagram.
Is USB functionality available on the TMS320F28062UPNT?
Yes, the TMS320F28062UPNT includes full-speed USB 2.0 support in both device and host modes. It features an integrated USB PHY with DP/DM pins (USB0DP/USB0DM), supporting CDC and DFU classes for firmware updates, real-time debug streaming, and configuration via standard USB cables. USB capability is explicitly listed for the "U" variant (e.g., TMS320F28062U) in the device comparison table, and TMS320F28062UPNT is a member of that variant family.
What package type and pin count does the TMS320F28062UPNT use?
The TMS320F28062UPNT uses an 80-pin LQFP (Low-Profile Quad Flatpack) package, designated as "PN" in TI documentation, with a 12.0 mm × 12.0 mm body size. It includes a thermally enhanced PowerPAD™ exposed pad that must be soldered to the PCB ground plane for effective heat dissipation. This package is distinct from the 100-pin PZ/PZP variants and is confirmed in TI's Mechanical, Packaging, and Orderable Information for TMS320F28062UPNT.
