Product details
Overview
TMS320F28069PZPS 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 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 outputs (8 HRPWM-capable), deployed in solar inverters, EV charging stations, and servo drives.
For engineers reviewing the TMS320F28069PZPS datasheet, TMS320F28069PZPS pinout, TMS320F28069PZPS application, or TMS320F28069PZPS equivalent, key selection criteria include its 100-pin HTQFP package with PowerPAD™ thermal enhancement, dual-edge HRPWM capability, on-chip temperature sensor, 128-bit code security, and USB 2.0 full-speed device/host support.
Technical Context
The TMS320F28069PZPS implements a Harvard bus architecture with atomic operations and unified memory programming, enabling deterministic real-time execution. Its dual-core structure pairs the 90-MHz C28x CPU with an independent 32-bit floating-point CLA accelerator for parallel control law execution.
Peripheral integration includes three eCAP modules, four HRCAP modules, two eQEP interfaces, and a 12-bit dual-sample-and-hold ADC with ratio-metric reference support (VREFHI/VREFLO). Clocking uses two internal zero-pin oscillators plus external crystal/CLK input, with PLL-based frequency synthesis and missing-clock detection.

FAQ
What is the operating temperature range for the TMS320F28069PZPS?
The TMS320F28069PZPS is rated for operation from –40°C to +125°C (S-grade), making it suitable for under-hood automotive applications and high-ambient industrial environments. This rating is validated per TI's characterization data and includes full functionality of all peripherals including ADC, ePWM, and USB across the full range.
Does the TMS320F28069PZPS support USB host mode?
Yes, the TMS320F28069PZPS supports both full-speed USB 2.0 device mode and full-speed or low-speed host mode. The USB PHY is integrated, requiring only external passive components (pull-up resistor, ESD protection); no external transceiver is needed. Host mode enables direct connection to USB HID devices or flash drives for firmware updates.
How many high-resolution PWM channels does the TMS320F28069PZPS provide?
The TMS320F28069PZPS provides 8 high-resolution PWM (HRPWM) channels, all derived from its 16 total ePWM outputs. Each HRPWM channel supports 150-ps resolution for fine-grained dead-time control and frequency modulation-critical for soft-switching topologies like LLC resonant converters and SiC/GaN gate drivers.
Is the TMS320F28069PZPS pin-compatible with other F2806x family members in the same package?
Yes, the TMS320F28069PZPS is pin-compatible with other 100-pin PZP-packaged F2806x variants (e.g., TMS320F28069M, TMS320F28069F) and shares identical signal mapping, power/ground pin locations, and JTAG interface layout. Functional differences (e.g., VCU presence, flash size) do not affect mechanical or electrical pin compatibility.
What debug interfaces are supported by the TMS320F28069PZPS?
The TMS320F28069PZPS supports IEEE 1149.1-compliant JTAG (TRST/TCK/TMS/TDI/TDO) for full hardware emulation, real-time debug, and boundary scan testing. It also supports serial boot modes via SCI/UART and USB-based firmware loading, enabling field updates without JTAG hardware.
