Product details
Overview
TMS320F28069MPZT 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. It delivers 16 ePWM channels (8 HRPWM-capable), 3 eCAP modules, 4 HRCAP modules, dual-sample-and-hold analog front-end, and on-chip temperature sensor - deployed in solar inverters, EV charging stations, and servo drive control modules.
For engineers reviewing the TMS320F28069MPZT datasheet, TMS320F28069MPZT pinout, TMS320F28069MPZT application, or TMS320F28069MPZT equivalent, key selection criteria include CLA-accelerated floating-point control loop execution, 100-pin HTQFP thermal performance, ePWM dual-edge modulation capability, and USB 2.0 device/host support for firmware updates and host-side diagnostics.
Technical Context
The TMS320F28069MPZT implements a Harvard-architecture C28x CPU with atomic instruction support and unified memory model, enabling deterministic real-time interrupt response under 11.11-ns cycle time. Its CLA operates independently of the main CPU to offload PID, field-oriented control (FOC), and observer computations using native 32-bit floating-point math.
Peripheral integration includes dual 12-bit ADCs with ratio-metric VREFHI/VREFLO references, analog comparators with internal 10-bit DACs routed directly to ePWM trip zones, and enhanced ePWM modules supporting frequency-modulated dual-edge control. The device uses a single 3.3-V supply with integrated voltage regulator and supports JTAG boundary scan per IEEE 1149.1.

FAQ
What is the maximum operating frequency and instruction cycle time of the TMS320F28069MPZT?
The TMS320F28069MPZT 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 –40°C to 105°C industrial temperature range and enables sub-microsecond execution of critical control tasks such as current-loop PI updates and space-vector modulation calculations within the TMS320F28069MPZT.
Does the TMS320F28069MPZT support USB functionality, and what modes are available?
Yes, the TMS320F28069MPZT integrates a full-speed USB 2.0 PHY supporting both device mode (for PC-connected firmware updates and debugging) and host mode (for connecting USB peripherals like flash drives or HID devices). USB operation is enabled on the dedicated USB0DP/USB0DM pins and requires no external transceiver, simplifying board design and reducing BOM cost for the TMS320F28069MPZT.
How many high-resolution PWM (HRPWM) channels does the TMS320F28069MPZT provide, and what is their timing resolution?
The TMS320F28069MPZT provides 8 HRPWM-capable channels among its 16 total ePWM outputs. Each HRPWM channel achieves 150-ps edge placement resolution, enabling precise gate timing for resonant topologies (e.g., LLC, ZVS) and wide-bandgap devices (GaN/SiC) where nanosecond-level control is essential - a key capability of the TMS320F28069MPZT.
What analog peripherals are integrated into the TMS320F28069MPZT, and how are they configured for motor control?
The TMS320F28069MPZT integrates a 12-bit dual-sample-and-hold ADC (3.46 MSPS, 16 channels), three analog comparators with internal 10-bit DACs, and an on-die temperature sensor. For motor control, ADC channels sample phase currents and DC-link voltage simultaneously, while comparators feed directly into ePWM trip zones for hardware-fast overcurrent shutdown - all coordinated within the TMS320F28069MPZT's real-time architecture.
Is the TMS320F28069MPZT pin-compatible with other devices in the F2806x family, and what package options exist?
The TMS320F28069MPZT uses the 100-pin HTQFP (PZP) package with PowerPAD™ thermal enhancement. It shares pinout compatibility with other 100-pin F2806x variants (e.g., TMS320F28069PZP), but differs from 80-pin versions (PN/PFP) and automotive Q1 variants. Pin mapping is validated per TI's SPRS698J datasheet Figure 6-2, confirming signal integrity and thermal performance for the TMS320F28069MPZT in industrial motor control layouts.
