Product details
Overview
TMS320F28065PZPQ 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 automotive-grade (AEC Q100) applications. It delivers 16 ePWM channels (8 HRPWM-capable), 3 eCAP modules, 2 eQEP interfaces, and dual-sample-and-hold analog front-end for precision current/voltage sensing.
For engineers reviewing the TMS320F28065PZPQ datasheet, TMS320F28065PZPQ pinout, TMS320F28065PZPQ application, or TMS320F28065PZPQ equivalent, key selection criteria include its AEC-Q100 qualification, 100-pin HTQFP PowerPAD™ package, 128KB flash/50KB RAM memory map, CLA-accelerated control loop execution, and support for InstaSPIN-FOC™ firmware deployment.
Technical Context
The TMS320F28065PZPQ implements a Harvard architecture C28x CPU with atomic instruction support and unified memory model, enabling deterministic real-time interrupt response under 11.11-ns cycle time. Its CLA operates independently of the main CPU to offload floating-point-intensive control law computations.
Peripheral integration includes dual 12-bit ADCs 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 high-frequency switching converters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28069PZPQ | 128KB flash, 50KB RAM, VCU, CLA, USB, eCAN - adds VCU and full USB 2.0 support vs. TMS320F28065PZPQ. | Required where Viterbi decoding or full-speed USB host mode is needed (e.g., wireless charging protocol stacks). | Select when advanced communication acceleration or USB host capability is mandatory; otherwise, TMS320F28065PZPQ offers optimal cost/performance balance. |
| TMS320F280049PZPQ | Newer generation: 100-MHz C28x, CLB, enhanced ADC (4-MSPS), larger RAM (164KB), but no VCU or InstaSPIN-FOC ROM. | Targeted for next-gen designs requiring configurable logic blocks and higher analog throughput, but lacks factory-tuned FOC libraries. | Choose for roadmap continuity and higher performance; retain TMS320F28065PZPQ for legacy InstaSPIN-FOC compatibility and proven AEC-Q100 field deployment. |
Compared with TMS320F28069PZPQ, the TMS320F28065PZPQ omits VCU and USB host mode but retains identical CLA, FPU, ePWM, and ADC capabilities - making it ideal for cost-sensitive automotive motor control where those features are unused. Against TMS320F280049PZPQ, it trades newer peripherals for mature, qualified firmware support and lower BOM cost.

FAQ
What is the maximum operating frequency and instruction cycle time of the TMS320F28065PZPQ?
The TMS320F28065PZPQ operates at a maximum CPU frequency of 90 MHz, delivering an instruction cycle time of 11.11 ns. This timing is guaranteed across the full –40°C to 125°C temperature range and 3.3-V supply, enabling deterministic execution of time-critical control loops in automotive and industrial environments.
Does the TMS320F28065PZPQ include a floating-point unit and control law accelerator?
Yes, the TMS320F28065PZPQ integrates both a native single-precision floating-point unit (FPU) and a programmable Control Law Accelerator (CLA). The CLA executes floating-point control code independently of the main C28x CPU, reducing latency in field-oriented control and observer calculations within the TMS320F28065PZPQ.
What analog peripherals are integrated into the TMS320F28065PZPQ?
The TMS320F28065PZPQ integrates a 12-bit, 3.46-MSPS ADC with dual sample-and-hold, 3 analog comparators with integrated 10-bit DACs, an on-chip temperature sensor, and ratio-metric VREFHI/VREFLO references. These enable high-fidelity current/voltage sensing and hardware-based fault protection without external components.
Is the TMS320F28065PZPQ qualified for automotive applications?
Yes, the TMS320F28065PZPQ carries AEC-Q100 Grade 1 qualification (–40°C to 125°C) and is explicitly designated for automotive use in its part number suffix 'Q'. It meets stringent reliability, ESD, and thermal requirements for under-hood power electronics including on-board chargers and traction inverters.
What package type and thermal considerations apply to the TMS320F28065PZPQ?
The TMS320F28065PZPQ uses a 100-pin HTQFP PowerPAD™ package (14.0 mm × 14.0 mm) with an exposed thermal pad. The pad must be soldered to the PCB ground plane using thermal vias - it is not electrically connected to internal VSS but is essential for dissipating up to 2.1 W under full load in automotive ambient conditions.
