Texas Instruments TMS320F28069MPNT

Overview

TMS320F28069MPNT 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 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 TMS320F28069MPNT datasheet, TMS320F28069MPNT pinout, TMS320F28069MPNT application, or TMS320F28069MPNT equivalent, key selection criteria include its dual-core architecture (C28x + CLA), high-resolution PWM timing capability, on-chip analog comparators with DACs, USB 2.0 device/host support, and AEC-Q100 qualification readiness via pin-compatible Q1 variants.

Technical Context

The TMS320F28069MPNT implements a Harvard bus architecture with atomic instruction execution and unified memory programming model, enabling deterministic real-time response. Its C28x CPU executes 32-bit fixed-point and single-precision floating-point operations natively via integrated FPU, while the independent 32-bit CLA offloads control-law computation without CPU intervention.

Peripheral integration includes dual-sample-and-hold 12-bit ADC with ratio-metric reference support, three eCAP modules, four HRCAP modules, two eQEP interfaces, and enhanced ePWM with dual-edge modulation. All peripherals are DMA-accessible and managed through a centralized PIE interrupt controller supporting nested vector processing.

Key Specifications

Pinout & Package

Package: 100-pin HTQFP (PZP) with exposed thermal pad (PowerPAD™), 14.0 mm × 14.0 mm body size. The PowerPAD must be soldered to PCB ground plane via thermal vias for effective heat dissipation; it is not electrically connected to internal VSS.

FAQ

What is the maximum operating frequency and instruction cycle time of the TMS320F28069MPNT?

The TMS320F28069MPNT operates at a maximum CPU frequency of 90 MHz, delivering an instruction cycle time of 11.11 ns. This timing is guaranteed across the full industrial temperature range (–40°C to 105°C) and under nominal 3.3-V supply conditions, enabling deterministic execution of time-critical control loops in motor and power applications.

Does the TMS320F28069MPNT include hardware acceleration for motor control algorithms?

Yes, the TMS320F28069MPNT integrates both a Floating-Point Unit (FPU) and a Programmable Control Law Accelerator (CLA). The CLA executes control-law code-including PID, field-oriented control, and observers-independently of the main C28x CPU, reducing latency and freeing CPU bandwidth for system-level tasks in TMS320F28069MPNT-based designs.

How many high-resolution PWM channels does the TMS320F28069MPNT support?

The TMS320F28069MPNT supports 8 high-resolution PWM (HRPWM) channels, all derived from its 8 ePWM modules. Each HRPWM channel enables fine edge positioning with resolution down to ≤150 ps, critical for optimizing switching losses in SiC and GaN-based power stages controlled by the TMS320F28069MPNT.

What analog-to-digital conversion capability does the TMS320F28069MPNT provide?

The TMS320F28069MPNT features a 12-bit dual-sample-and-hold ADC with up to 16 input channels and a maximum sampling rate of 3.46 MSPS. It supports ratio-metric referencing (VREFHI/VREFLO), simultaneous sampling across both ADC banks, and direct DMA access-enabling high-fidelity current/voltage sensing in TMS320F28069MPNT motor and power control systems.

Is the TMS320F28069MPNT pin-compatible with other devices in the F2806x family?

Yes, the TMS320F28069MPNT shares identical pinout and peripheral mapping with other 100-pin PZ/PZP variants in the F2806x family, including TMS320F28069PZP and TMS320F28069QPZP. This allows direct substitution in existing PCB layouts when upgrading thermal performance or automotive qualification without redesigning the board.
