Product details
Overview
TMS320F28069UPFPS from Texas Instruments is a 90-MHz C28x-based real-time microcontroller with integrated FPU, CLA, and VCU, designed for high-precision motor control and digital power conversion. It delivers 11.11-ns instruction cycle time, 128KB flash, 50KB RAM, 16-channel 12-bit ADC at 3.46 MSPS, and 16 ePWM channels (8 HRPWM-capable), operating from a single 3.3-V supply in industrial temperature range (–40°C to 105°C).
For engineers reviewing the TMS320F28069UPFPS datasheet, TMS320F28069UPFPS pinout, TMS320F28069UPFPS application, or TMS320F28069UPFPS equivalent, key selection criteria include its dual-core architecture (C28x + CLA), on-chip analog integration (comparators, DACs, temperature sensor), USB 2.0 support, and PowerPAD™ HTQFP-80 thermal package-critical for servo drives, solar inverters, and EV charging modules.
Technical Context
The TMS320F28069UPFPS implements a Harvard bus architecture with atomic operations and unified memory programming, enabling deterministic real-time execution. Its CLA executes floating-point math independently of the main CPU, accelerating control law computation without interrupt latency.
Peripheral integration includes three eCAP modules, four HRCAP modules, two eQEP interfaces, dual-sample-and-hold ADC with ratio-metric reference support, and enhanced trip-zone protection across eight ePWM modules-enabling precise timing-critical actuation in closed-loop systems.

Pin assignments USB0DP and USB0DM are dedicated on the 80-pin PFP package, enabling firmware updates, real-time debug, and host-side communication without external transceivers.
How many high-resolution PWM channels does the TMS320F28069UPFPS support?
The TMS320F28069UPFPS supports 8 high-resolution PWM (HRPWM) channels, distributed across its 8 ePWM modules. Each HRPWM channel achieves sub-nanosecond resolution for precise dead-time control and phase-shifted modulation-critical for SiC/GaN-based power stages in high-efficiency converters.
Is the TMS320F28069UPFPS pin-compatible with other F2806x variants?
Yes, the TMS320F28069UPFPS shares identical pinout with other 80-pin PFP-packaged F2806x devices (e.g., TMS320F28069PFP, TMS320F28069MPFP), including matching GPIO, peripheral, power, and debug signal locations. This enables direct substitution within the same footprint for design reuse and variant optimization.
What security features are implemented in the TMS320F28069UPFPS?
The TMS320F28069UPFPS includes 128-bit code security module (CSM) with password protection, locking secure memory blocks (flash, RAM, OTP), and prevention of firmware reverse-engineering. Security is enforced at boot and runtime, and the 1KB OTP ROM stores immutable keys and calibration data resistant to reprogramming.
