F28P550SJ9PMR overview
F28P550SJ9PMR is a component documented by Texas Instruments. The PDF description identifies it as "TMS320F28P55x Real-Time Microcontrollers REVISED JUNE 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.
- Twenty-four PWM channels, all supporting frequency-independent resolution modes, enable control of various power stages from a 3-phase inverter to power factor correction and advanced multilevel power topologies.
- 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.
- TI recommends placing a decoupling capacitor near each VDD pin with a minimum total capacitance of approximately 10 µF.
- The AGPIO analog pin path contains an extra series switch of 53 Ω.
- This node can be disturbed when the ADC samples the channel (depending on the prior voltage stored on the ADC sample and hold capacitor), and this disturbance can cause a false CMPSS event of up to 50ns.
Topics covered by the datasheet
The document includes sections related to:
- TMS320F28P550SJ_V01 TI
- 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.
