Product details
Overview
TMS320F28067PNT 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 industrial inverters and EV charging modules.
For engineers reviewing the TMS320F28067PNT datasheet, TMS320F28067PNT pinout, TMS320F28067PNT application, or TMS320F28067PNT equivalent, key selection criteria include ePWM channel count (16 total, 8 HRPWM-capable), on-chip flash (64 KB), RAM (50 KB), USB 2.0 availability, and thermal rating (–40°C to 105°C).
Technical Context
The TMS320F28067PNT implements a Harvard-architecture C28x CPU with atomic instruction execution and unified memory mapping, paired with a dedicated 32-bit floating-point CLA that runs control law code independently of the main CPU. Its VCU extends instruction set support for CRC, complex math, and Viterbi operations.
Peripheral integration includes dual-sample-and-hold ADC with 16-channel input muxing, three eCAP modules, four HRCAP modules, two eQEP interfaces, and eight ePWM modules-each with independent 16-bit timers and dual-edge HRPWM capability for precise timing modulation.

Yes, the TMS320F28067PNT integrates a native single-precision floating-point unit (FPU) alongside its C28x CPU core. This allows direct execution of IEEE 754-compliant floating-point arithmetic in hardware, significantly accelerating mathematical operations used in motor control and digital power algorithms without software emulation overhead.
How much on-chip flash and RAM does the TMS320F28067PNT provide?
The TMS320F28067PNT provides 64 KB of on-chip flash memory (organized as 16-bit words across 8 equal sectors) and 50 KB of on-chip SARAM (also 16-bit words). Flash includes code security features, while RAM is partitioned into secure and non-secure blocks for firmware protection and real-time task isolation.
Is USB functionality available on the TMS320F28067PNT?
No, USB 2.0 is not available on the TMS320F28067PNT. USB support is limited to the TMS320F2806xU, TMS320F2806xM, and TMS320F2806xF variants per TI's device comparison table. The TMS320F28067PNT retains full SCI/UART, SPI, I²C, McBSP, and eCAN interfaces for communication.
What package type and thermal characteristics apply to the TMS320F28067PNT?
The TMS320F28067PNT is offered exclusively in the 80-pin LQFP (PN) package, 12.0 mm × 12.0 mm body size. It features a thermally enhanced PowerPAD™ exposed pad that must be soldered to the PCB ground plane for effective heat dissipation, though it is not electrically connected to internal VSS.
