: Features an integrated LVDS (Low-Voltage Differential Signaling) transmitter. This enables a direct, noise-immune interface to digital LCD glass panels without requiring external conversion chips. Key Technical Specifications
At its core, the TSUM1PFR-LF is a "total solution" IC for LCD monitors, capable of handling panel resolutions up to . It integrates an analog interface, a display processing engine, a microcontroller, and an output interface into a single chip, significantly reducing the bill of materials for display manufacturers.
For design engineers, the verified parameters, voltage ranges (1.8V to 5.5V), and thermal limits (340mW Pd) in this article provide the critical data for integrating the part into a new system. For technicians, the pin definitions and common application circuits detailed here serve as a direct reference for troubleshooting and repair. When sourcing, always cross-reference the markings with these verified specifications to ensure authenticity and compatibility.

Features an integrated triple-ADC (Analog-to-Digital Converter) and PLL (Phase-Locked Loop) for analog signal processing.
Assume the function based on package. If the TSUM1PFRLF is:
MStar Semiconductor (now part of MediaTek) The maximum recommended profile peak temperature is 260°C
High-speed differential pairs routing directly to the LCD panel's T-CON board.
The TSUM1PFRLF integrates several critical functions onto a single chip, reducing overall monitor manufacturing costs and footprint:
Email the technical support teams at , ON Semi , and Microchip with the full part number. Request a “product discontinuation notice” (PDN) or “final datasheet.” If they confirm it is not their part, the component may be OEM-specific (e.g., made for Samsung, LG, or Panasonic). a display processing engine
The maximum recommended profile peak temperature is 260°C for up to 10 seconds . Exceeding this limit risks damaging the internal silicon junctions.
Keep the analog RGB traces leading to the Triple-ADC pins as short and isolated as possible. Run ground isolation traces around them to prevent digital cross-talk from the high-speed LVDS output lines.
