Product details
Overview
TMS320F28067PFPS 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), and 54 GPIOs. It targets high-precision motor control and digital power conversion in industrial inverters, EV charging stations, and solar power optimizers.
For engineers reviewing the TMS320F28067PFPS datasheet, TMS320F28067PFPS pinout, TMS320F28067PFPS application, or TMS320F28067PFPS equivalent, key selection criteria include its 80-pin HTQFP PowerPAD™ package, dual-edge HRPWM capability, on-chip temperature sensor, 128KB flash/50KB RAM memory map, and USB 2.0 host/device support.
Technical Context
The TMS320F28067PFPS implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory model, enabling deterministic real-time control loops. Its CLA executes floating-point math independently of the main CPU, accelerating closed-loop computations for field-oriented control (FOC) and sensorless algorithms.
Peripheral integration includes dual-sample-and-hold ADC with ratio-metric VREFHI/VREFLO references, analog comparators routed directly to ePWM trip zones, and enhanced ePWM modules supporting frequency modulation via dual-edge control - critical for high-efficiency SiC/GaN gate drive timing.

Does the TMS320F28067PFPS include USB functionality, and what modes does it support?
Yes, the TMS320F28067PFPS integrates a full-speed USB 2.0 peripheral supporting both device mode (for firmware updates and debug) and host mode (for connecting peripherals like UART-to-USB bridges). USB signals are routed to dedicated pins USB0DP and USB0DM on the 80-pin PFP package.
How much on-chip memory does the TMS320F28067PFPS provide, and how is it allocated?
The TMS320F28067PFPS provides 128KB of secure on-chip flash memory (organized in eight 16KB sectors) and 50KB of on-chip SARAM. Memory includes 32KB boot ROM, 1KB OTP, and configurable access rights enforced by the Code Security Module (CSM) to protect firmware IP.
What ADC performance specifications apply to the TMS320F28067PFPS?
The TMS320F28067PFPS features a 12-bit dual-sample-and-hold ADC with 3.46 MSPS throughput, 16 input channels, and 289-ns conversion time. It supports ratio-metric referencing (VREFHI/VREFLO) and simultaneous sampling across multiple channels - essential for three-phase current sensing in motor control.
Is the TMS320F28067PFPS pin-compatible with other devices in the F2806x family?
The TMS320F28067PFPS shares the same 80-pin PFP package footprint and pinout with TMS320F28069PFP and TMS320F28066PFP. However, functional differences exist - notably, TMS320F28067PFPS includes USB while TMS320F28069PFP includes VCU; therefore, PCB layout reuse requires verification of peripheral signal routing and power sequencing.
