How to Find the HX8872F Datasheet (PDF) – Latest Update (UPD)

If you landed here searching for “HX8872F datasheet PDF UPD”, you’re likely working on a TFT LCD driver IC project. The HX8872 series (often from Himax or older ILI/Himax compatibles) can be tricky to locate – especially specific suffixes like “F” or “UPD” codes.

Let me save you hours of dead-end searches.

Q2: The datasheet says "Under NDA." How do I get the "UPD" version for free?

Legally, you cannot get the full 200-page specification. However, the Public Short Form Datasheet (Version 1.2) is available on DocGo and OEMSecrets. This includes 90% of what you need for basic operation.

Issue 3: Partial Sleep Wake-up

Original: After exiting deep standby, the internal oscillator wouldn't restart. UPD Fix: The initialization sequence now requires a dummy read from register 0x0A before sending 0x11. This is explicitly noted in the Rev C addendum. hx8872f+datasheet+pdf+upd

Recommended Decoupling: Place 10µF and 0.1µF capacitors as close as possible to pins VDD_AMP (Pin 19) and VDD_CORE (Pin 38). The UPD datasheet emphasizes using X7R ceramic caps, not Y5V, due to voltage coefficient.

2. Datasheet Search Engines

Websites like:

• Digikey (https://www.digikey.com/)
• Mouser (https://www.mouser.com/)
• Allied Electronics (https://www.alliedelec.com/)
• ChipMLCC or other electronic component distributors often have extensive databases of datasheets.

You can search for "HX8872F datasheet" on these platforms.

Key Features at a Glance

• Resolution Support: 800-channel source driver.
• Voltage Range: Analog power supply from 6.0V to 13.5V; Digital core from 2.3V to 3.6V.
• Interface: Supports RGB (Parallel), SPI, and MIPI DSI (depending on sub-variant).
• Outputs: 800 RGB outputs capable of driving high-load LCD capacitors.
• Gamma Correction: Programmable 10-bit gamma correction for superior color accuracy.

If your project involves a 4.3-inch, 5-inch, or 7-inch display with a 40-pin FPC, there is a high probability the HX8872F is the engine under the hood.

Q3: Does "UPD" refer to a specific file like "HX8872F_UPD.bin"?

Yes. Some Chinese LCD driver boards (e.g., those using the F1C200s CPU) require an .upd file to program the HX8872D initial registers via USB. Do not confuse this binary update with the PDF datasheet. How to Find the HX8872F Datasheet (PDF) –

Recommendation

• Download the PDF from the chip manufacturer first; if unavailable, use a reputable distributor (Digi-Key/Mouser) mirror.
• Compare revision numbers and dates; use the newest revision labeled "update", "upd", or with a higher revision code.
• Validate critical specs (voltage, current, timing) against at least two sources before designing.

If you want, I can:

1. Search for the latest HX8872F datasheet PDF and fetch the official revision (I will return filename, revision/date, and a brief checklist of key specs), or
2. Produce a one‑page review summarizing electrical specs and recommended footprint assuming I find the official datasheet.
