Product details
Overview
TMS320F28069FPZT from Texas Instruments is a 90-MHz C28x-based real-time microcontroller with integrated FPU, CLA, and VCU, designed for closed-loop motor control and digital power applications. It delivers 11.11-ns instruction cycle time, 128KB flash, 50KB RAM, 16-channel 12-bit ADC (3.46 MSPS), and 16 ePWM outputs - including 8 HRPWM-capable channels - in a thermally enhanced 100-pin HTQFP package rated for –40°C to 105°C operation.
For engineers reviewing the TMS320F28069FPZT datasheet, TMS320F28069FPZT pinout, TMS320F28069FPZT application, or TMS320F28069FPZT equivalent, key selection criteria include its dual-core architecture (C28x + CLA), on-chip analog integration (comparators, DACs, temperature sensor), USB 2.0 support, and AEC-Q100–qualified variants for automotive traction inverters and EV charging modules.
Technical Context
The TMS320F28069FPZT implements a Harvard bus architecture with unified memory programming model and atomic operations, enabling deterministic real-time execution. Its C28x CPU executes 16×16 and 32×32 MAC operations natively, while the independent 32-bit floating-point CLA offloads control law computation without CPU intervention.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO references, ePWM modules supporting dual-edge modulation, and three analog comparators with internal 10-bit references routed directly to PWM trip zones - all optimized for fast current/voltage loop closure in inverter gate drive systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049C | Higher 100-MHz CPU, CLB logic blocks, improved ADC SNR, but no VCU or InstaSPIN-FOC ROM. | Better suited for next-gen SiC/GaN designs requiring adaptive control and higher sampling rates. | Select when migrating to F28004x roadmap with need for configurable logic and enhanced analog performance. |
| TMS320F28069M | Same package and pinout; adds InstaSPIN-MOTION™ ROM and motion control libraries, but reduced flash (64KB) and RAM (34KB). | Optimized for servo drives with pre-validated motion profiling, not general-purpose inverter control. | Choose only if leveraging TI's InstaSPIN-MOTION libraries; otherwise, TMS320F28069FPZT offers superior memory and peripheral headroom. |
Compared with TMS320F280049C and TMS320F28069M, the TMS320F28069FPZT provides balanced performance for cost-sensitive industrial inverters - retaining VCU acceleration and full 128KB flash while avoiding roadmap obsolescence risks associated with discontinued InstaSPIN-MOTION support.

FAQ
What is the maximum operating frequency of the TMS320F28069FPZT?
The TMS320F28069FPZT operates at a maximum CPU frequency of 90 MHz, delivering an instruction cycle time of 11.11 ns. This speed is achieved using an internal PLL with external crystal or oscillator input, and it is fully supported across the specified industrial temperature range (–40°C to 105°C). The TMS320F28069FPZT maintains timing compliance under worst-case voltage and temperature conditions per TI's SPRS698J datasheet.
Does the TMS320F28069FPZT support USB functionality?
Yes, the TMS320F28069FPZT integrates a full-speed USB 2.0 controller supporting both device and host modes. It includes dedicated USB0DP and USB0DM pins, on-chip transceiver, and endpoint buffers - enabling direct connection to USB hosts or peripherals without external PHY components. This capability is confirmed in the Device Comparison table and functional block diagram of the TMS320F28069FPZT datasheet.
How many PWM outputs does the TMS320F28069FPZT provide, and what is their resolution?
The TMS320F28069FPZT provides 16 ePWM outputs across eight modules, with eight channels supporting high-resolution PWM (HRPWM) mode. HRPWM achieves sub-150-ps timing resolution through digital fine-tuning, while standard ePWM offers 16-bit counter resolution. All 16 outputs are accessible on the 100-pin PZP package and support independent dead-time insertion, trip-zone protection, and synchronization signals.
What analog peripherals are integrated into the TMS320F28069FPZT?
The TMS320F28069FPZT integrates a 12-bit, 3.46-MSPS ADC with dual sample-and-hold, three analog comparators with internal 10-bit DAC references, an on-die temperature sensor, and ratio-metric VREFHI/VREFLO reference inputs. These peripherals are tightly coupled to ePWM trip zones and DMA for real-time signal acquisition and fault response - all documented in Sections 3.2 and 7.6 of the TMS320F28069FPZT datasheet.
Is the TMS320F28069FPZT pin-compatible with other F2806x devices?
Yes, the TMS320F28069FPZT in the 100-pin PZP package shares identical pinout and footprint with other F2806x variants offered in the same package, including TMS320F28069M, TMS320F28069F, and TMS320F28068M. This allows hardware reuse across firmware variants targeting InstaSPIN-FOC, motion control, or general-purpose real-time applications - as verified in TI's Mechanical, Packaging, and Orderable Information document.
