Product details
Overview
TMS320F28062PFPQR 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 TMS320F28062PFPQR datasheet, TMS320F28062PFPQR pinout, TMS320F28062PFPQR application, or TMS320F28062PFPQR equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use-value analysis, and validated alternative options for high-precision timing-critical control systems.
Technical Context
The TMS320F28062PFPQR implements a Harvard-architecture C28x CPU with atomic instruction execution, fast interrupt response, and unified memory model-enabling deterministic real-time control loops. Its dual 16-bit MAC units and 32×32 multiply-accumulate capability support complex motor algorithms without software overhead.
It integrates a dedicated 32-bit floating-point CLA that executes control law code independently of the main CPU, while the VCU accelerates Viterbi, CRC, and complex math operations. The device uses two internal zero-pin oscillators and supports PLL-based clock scaling up to 90 MHz with missing-clock detection.

FAQ
What is the maximum operating temperature rating for the TMS320F28062PFPQR?
The TMS320F28062PFPQR is qualified for operation from –40°C to +125°C and carries AEC Q100 Grade 1 automotive qualification (Q-grade). This rating applies to the full 80-pin HTQFP PowerPAD™ package and is validated per JEDEC JESD22-A108. Thermal performance assumes proper PCB thermal land design per TI's PowerPAD guidelines.
Does the TMS320F28062PFPQR include a hardware floating-point unit?
Yes, the TMS320F28062PFPQR integrates a native single-precision IEEE 754-compliant floating-point unit (FPU) as part of its C28x CPU core. This eliminates software emulation overhead and enables direct C-language implementation of trigonometric, logarithmic, and matrix operations used in field-oriented control (FOC) and observer algorithms.
How many high-resolution PWM channels does the TMS320F28062PFPQR support?
The TMS320F28062PFPQR supports 8 high-resolution PWM (HRPWM) channels-distributed across its 8 ePWM modules. Each HRPWM channel delivers 150-ps resolution via digital fine-tuning, enabling precise dead-time control and frequency modulation essential for resonant converters and SiC/GaN gate driving.
Is USB functionality available on the TMS320F28062PFPQR?
No, USB is not implemented on the TMS320F28062PFPQR. Per TI's official device comparison table (SPRS698J), USB 2.0 is only available on F2806xU, F2806xM, and F2806xF variants-not on the base F28062 or F28062F. The TMS320F28062PFPQR retains all other serial interfaces: 2 SCI/UART, 2 SPI, 1 I²C, 1 eCAN, and 1 McBSP.
What memory security features are included in the TMS320F28062PFPQR?
The TMS320F28062PFPQR includes a Code Security Module (CSM) with 128-bit password protection, locking access to on-chip Flash, SARAM, and OTP memory blocks. Once secured, memory contents cannot be read via JTAG or boot ROM, and unauthorized debug access triggers irreversible security lockout-protecting proprietary motor control firmware from cloning or reverse engineering.
