The provides the essential technical blueprints for a highly integrated graphics processing system-on-chip (SoC) designed by MSTAR Semiconductor (now MediaTek) . Engineered primarily for flat-panel LCD monitors and entry-level display systems, this display controller integrates an analog front-end (AFE), a scaling engine, an internal microcontroller, and an LVDS transmitter into a single, cost-effective LQFP-64 package .
For system integration and schematic design, the foundational electrical and physical constraints of the TSUM1PFR-LF must be maintained within its safe operating limits. Specification LQFP-64 (Low-profile Quad Flat Pack) 64 pins, compact surface-mount package Lead-Free Status RoHS Compliant ("-LF" suffix) Environmentally friendly lead-free construction Operating Temperature -40°C to 105°C ( TAcap T sub cap A Extended industrial-grade temperature tolerance Maximum Resolution WXGA+ / SXGA+ Supports standard 4:3, 5:4, and 16:10 aspect ratios Output Interface Single/Dual Link LVDS Direct digital panel interface connection Storage Condition Dry Storage Cabinet Requires humidity-controlled packaging prior to assembly Key Functional Architecture
The chip features a high-speed integrated Triple-ADC/PLL (Analog-to-Digital Converter / Phase-Locked Loop). This allows it to process high-resolution analog RGB input signals, ensuring crisp image reproduction from legacy VGA sources. B. Scaler Engine (WXGA+/SXGA+)
It features a robust scaling engine that adapts incoming video signals to the native resolution of the LCD panel. Tsum1pfr-lf Datasheet
The datasheet specifies built-in power saving loops that scale down power draw during sleep or inactive signal modes. Additionally, its clock trees support . This spreads out electromagnetic peak energy, helping commercial monitor boards pass stringent Electromagnetic Interference (EMI) certifications. Pin Layout and Signal Routing (LQFP-64)
Capable of handling panel resolutions up to WXGA+ (1440x900) and SXGA+ (1400x1050) at 60Hz.
The Tsum1pfr-lf datasheet highlights the following key features: The provides the essential technical blueprints for a
Enhances video quality from composite sources. 2.3 Output Interface
Because MStar Semiconductor was acquired and integrated into MediaTek, the TSUM1PFR-LF is classified as a legacy component with stable market availability rather than active new-product-development cycles.
