Product details
Overview
TMS320F28065UPZT from Texas Instruments is a 90-MHz C28x-based real-time microcontroller with integrated FPU, CLA, 12-bit 3.46-MSPS ADC, 8 ePWM modules (16 channels, 8 HRPWM-capable), and dual-sample-and-hold for motor control and digital power applications. It features 64KB flash, 34KB RAM, 3 eCAP, 4 HRCAP, 2 eQEP, eCAN, USB 2.0, and 54 GPIOs in a 100-pin HTQFP package.
For engineers reviewing the TMS320F28065UPZT datasheet, TMS320F28065UPZT pinout, TMS320F28065UPZT application, or TMS320F28065UPZT equivalent, key selection criteria include HRPWM resolution for inverter timing, CLA offloading capability for real-time control loops, ADC throughput and channel count for sensor acquisition, USB host/device support for firmware updates, and thermal performance of the PZP PowerPAD™ package in high-power drive systems.
Technical Context
The TMS320F28065UPZT implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory mapping, enabling deterministic interrupt latency under 6-cycle response. Its CLA operates independently of the main CPU to execute floating-point control law code-such as field-oriented control (FOC) inner-loop calculations-without CPU intervention.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO references, analog comparators with internal 10-bit DACs routed directly to ePWM trip zones, and enhanced HRPWM modules supporting dual-edge modulation for precise frequency control in resonant converters and servo drives.

FAQ
What is the maximum ADC sampling rate supported by the TMS320F28065UPZT?
The TMS320F28065UPZT supports a maximum ADC sampling rate of 3.46 million samples per second (MSPS) with 12-bit resolution and dual sample-and-hold capability. This enables simultaneous acquisition of two analog signals per conversion cycle, which is essential for synchronized current sensing in three-phase motor control applications. The 289 ns conversion time ensures minimal latency in real-time control loops.
Does the TMS320F28065UPZT include a floating-point unit and control law accelerator?
Yes, the TMS320F28065UPZT integrates both a native single-precision floating-point unit (FPU) and a programmable Control Law Accelerator (CLA). The CLA operates independently of the main C28x CPU and executes floating-point control code-such as field-oriented control inner loops-without CPU intervention, reducing latency and improving determinism in high-speed motor and power control applications.
What package type and thermal characteristics does the TMS320F28065UPZT use?
The TMS320F28065UPZT uses a 100-pin PowerPAD™ HTQFP (PZP) package measuring 14 mm × 14 mm with an exposed thermal pad. The PowerPAD must be soldered to the PCB ground plane using thermal vias to achieve optimal thermal performance. Unlike standard QFP packages, this thermally enhanced design significantly improves heat dissipation for sustained operation in high-power motor drive and inverter applications.
How many enhanced PWM (ePWM) modules and high-resolution PWM (HRPWM) channels does the TMS320F28065UPZT support?
The TMS320F28065UPZT integrates 8 ePWM modules providing 16 total PWM outputs, with 8 of those channels supporting high-resolution PWM (HRPWM) mode. HRPWM delivers 150-ps timing resolution and dual-edge modulation capability, enabling precise dead-time control and soft-switching in resonant topologies such as LLC and phase-shifted full-bridge converters used in EV chargers and server PSUs.
Is USB functionality available on the TMS320F28065UPZT, and what modes does it support?
Yes, the TMS320F28065UPZT includes a USB 2.0 interface supporting full-speed device mode (12 Mbps) and full-speed or low-speed host mode. Pins USB0DP (Pin 26) and USB0DM (Pin 27) are dedicated differential signals requiring appropriate termination and ESD protection. This enables firmware updates, configuration programming, and host-side diagnostics in embedded power systems without external USB controllers.
