Product details
Overview
TMS320F28069FPZTR 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 conversion. It delivers 11.11-ns instruction cycle time, 128KB flash, 50KB RAM, 16-channel ePWM (8 HRPWM-capable), 12-bit 3.46-MSPS ADC with dual S/H, and eCAN/USB/SCI/SPI/I²C interfaces - deployed in solar inverters, EV charging stations, and servo drive control modules.
For engineers reviewing the TMS320F28069FPZTR datasheet, TMS320F28069FPZTR pinout, TMS320F28069FPZTR application, or TMS320F28069FPZTR equivalent, key selection criteria include its 100-pin HTQFP (PZP) package, single 3.3-V supply operation, -40°C to 105°C temperature range, and hardware-accelerated real-time control peripherals including CLA and VCU.
Technical Context
The TMS320F28069FPZTR implements a Harvard-architecture C28x CPU core with atomic operations and fast interrupt response, coupled with a dedicated 32-bit floating-point CLA that executes control law code independently of the main CPU. Its VCU extends the instruction set for complex math, CRC, and Viterbi operations - enabling deterministic execution of field-oriented control (FOC) algorithms without CPU load.
Peripheral integration includes eight ePWM modules with dual-edge modulation capability, three eCAP modules, four HRCAP modules, two eQEP modules, and a 12-bit ADC with ratio-metric reference support (VREFHI/VREFLO). All analog comparators feature internal 10-bit references and direct routing to ePWM trip zones for hardware-protected fault response.

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, enhanced analog (2×16-bit ADC), 256KB flash - but no VCU or InstaSPIN-FOC ROM. | Targets next-gen digital power with configurable logic and higher precision sensing - not drop-in compatible due to peripheral register map changes. | Select for new designs needing CLB-based custom analog trigger logic or dual 16-bit ADCs; requires full firmware porting. |
| TMS320F28069M | Same package/peripherals but adds InstaSPIN-MOTION™ ROM library - discontinued for new designs per TI documentation. | Pre-integrated motion control libraries for BLDC/PMSM; limited to legacy maintenance where InstaSPIN-MOTION is already deployed. | Only for continuity in existing InstaSPIN-MOTION designs; not recommended for new projects per TI's roadmap guidance. |
Compared with TMS320F28069FPZTR, the TMS320F280049C offers higher performance and modern peripherals but requires redesign, while the TMS320F28069M provides legacy motion libraries at the cost of TI's discontinued support - making the TMS320F28069FPZTR optimal for stable, production-ready industrial control with full VCU/CLA acceleration.

FAQ
What is the operating temperature range for the TMS320F28069FPZTR?
The TMS320F28069FPZTR is rated for industrial operation from –40°C to 105°C (T-grade). This range is validated per TI's SPRS698J datasheet and applies to the 100-pin PZP package. It does not support the extended –40°C to 125°C (S/Q-grade) range offered by automotive variants like TMS320F28069QPZP.
Does the TMS320F28069FPZTR include USB functionality?
Yes, the TMS320F28069FPZTR integrates a full-speed USB 2.0 peripheral supporting both device and host modes. Pins USB0DP (Pin 26) and USB0DM (Pin 27) provide the differential interface - no external transceiver is required for basic USB communication, firmware updates, or debug via USB CDC.
How many high-resolution PWM channels does the TMS320F28069FPZTR support?
The TMS320F28069FPZTR supports 8 high-resolution PWM (HRPWM) channels, distributed across its 8 ePWM modules. Each HRPWM channel provides 150-ps resolution fine adjustment capability - critical for minimizing dead-time distortion in SiC/GaN-based power converters.
Is the TMS320F28069FPZTR pin-compatible with other F2806x family members?
The TMS320F28069FPZTR uses the 100-pin PZP HTQFP package and shares identical pinout with TMS320F28069PZP and TMS320F28069QPZP. However, it is not pin-compatible with 80-pin variants (e.g., TMS320F28069PFP) or functionally reduced derivatives like TMS320F28062F due to differing peripheral allocations and pin muxing.
What security features are implemented in the TMS320F28069FPZTR?
The TMS320F28069FPZTR includes a Code Security Module (CSM) with 128-bit password protection, locking access to flash, RAM, and OTP memory. Once secured, firmware cannot be read out or modified without the correct password - preventing reverse engineering and unauthorized firmware cloning in production systems.
