Texas Instruments TMS320F28062PZTR

Overview

TMS320F28062PZTR 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 TMS320F28062PZTR datasheet, TMS320F28062PZTR pinout, TMS320F28062PZTR application, or TMS320F28062PZTR equivalent, key selection criteria include ePWM channel count (16), HRPWM capability (8 channels), on-chip flash (64 KB), RAM (34 KB), and 100-pin LQFP package with 54 GPIOs and dual-sample-and-hold ADC architecture.

Technical Context

The TMS320F28062PZTR implements a Harvard-architecture C28x CPU with atomic instruction execution, fast interrupt response, and unified memory model. It integrates a dedicated 32-bit floating-point CLA that runs independently of the main CPU to offload control-law computation.

Its analog subsystem includes three comparators with internal 10-bit DACs routed directly to ePWM trip zones, a 12-bit dual-S/H ADC with 16-channel input multiplexing and ratio-metric reference support (VREFHI/VREFLO), and hardware-accelerated VCU for CRC and complex math operations.

FAQ

What is the maximum operating frequency of the TMS320F28062PZTR?

The TMS320F28062PZTR operates at a maximum CPU frequency of 90 MHz, delivering a 11.11-ns instruction cycle time. This speed is achieved using an internal PLL with external crystal or oscillator input, and is fully supported across its –40°C to 105°C industrial temperature range. The TMS320F28062PZTR maintains timing integrity under voltage and thermal variation per TI's published electrical characteristics.

Does the TMS320F28062PZTR include a floating-point unit?

Yes, the TMS320F28062PZTR integrates a native single-precision floating-point unit (FPU) as part of its C28x CPU core. This eliminates software-emulated floating-point overhead and accelerates mathematical operations used in motor control algorithms, such as Park/Clarke transforms and PID computations. The FPU is fully IEEE 754-compliant and accessible in both C/C++ and assembly code for the TMS320F28062PZTR.

How many PWM channels does the TMS320F28062PZTR support, and which are high-resolution?

The TMS320F28062PZTR supports 16 total ePWM channels across eight modules, with 8 channels capable of high-resolution PWM (HRPWM). These HRPWM channels deliver <150-ps resolution and support dual-edge modulation-critical for SiC/GaN gate drivers and resonant converter topologies. All 16 channels are accessible via multiplexed GPIO pins on the 100-pin PZ package of the TMS320F28062PZTR.

What ADC performance specifications apply to the TMS320F28062PZTR?

The TMS320F28062PZTR features a 12-bit analog-to-digital converter with dual sample-and-hold architecture, achieving 3.46 MSPS aggregate throughput and 289-ns conversion time. It supports up to 16 input channels across two independent banks (A/B), enabling simultaneous sampling for vector control. Input range is 0–3.3 V with ratio-metric VREFHI/VREFLO referencing, and the ADC is DMA-accessible for zero-CPU-overhead data transfer.

Is the TMS320F28062PZTR pin-compatible with other F2806x family members?

The TMS320F28062PZTR shares the same 100-pin LQFP (PZ) package footprint and pinout with TMS320F28069PZTR, TMS320F28067PZTR, and TMS320F28066PZTR, enabling direct PCB reuse within the F2806x PZ variant group. However, functional differences-including flash size (64 KB vs. 128 KB), RAM (34 KB vs. 50 KB), and peripheral inclusion (e.g., VCU presence)-require firmware and configuration validation when substituting. The TMS320F28062PZTR is not pin-compatible with PFP, PN, or PZP variants.
