F29H85XDM7 overview
F29H85XDM7 is a component documented by Texas Instruments. The PDF description identifies it as "F29H85x, F29P58x, and F29P32x Real-Time Microcontrollers REVISED DECEMBER 2025." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- Due to the C29 CPU architecture and tightly coupled peripherals (PWM, ADC, CMPSS), we see better performance with a 200MHz C29 core versus our competition running at higher CPU clock speed for certain applications – backed by customer benc.
- Thirty-six frequency-independent PWMs, all with high-resolution capability, enable control of multiple power stages, from 3-phase inverters to advanced multilevel power topologies.
- Each subsystem consists of a C28x CPU and a parallel control law accelerator (CLA), each running at 200 MHz.
- Other capabilities include up to 1.28MB of flash, 11 windowed comparators with dual-ramp generators, lockstep capability and a CLA module running at 200MHz.
- An external pullup resistor (recommended 2.2 kΩ) on the TMS pin to VDDIO should be placed on the board to keep JTAG in reset during normal operation.
- A resistor between 2.2 kΩ and 10 kΩ should be placed between XRSn and VDDIO.
- If a capacitor is placed between XRSn and VSS for noise filtering, it should be 100 nF or smaller.
Topics covered by the datasheet
The document includes sections related to:
- Package Information
Engineering review checklist
- Confirm supply rails, clock limits, memory size, peripheral mapping and I/O voltage compatibility.
- Check package pinout, boot configuration, programming interface and silicon-revision errata.
- Budget decoupling, thermal margin, startup timing and firmware recovery behavior before release.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
