Processors / Microcontrollers (Multimedia ICs) 2. Key Features of TSUM1PFR-LF
The TSUM1PFR-LF uses the (Low-Profile Quad Flat Package) form factor, which offers a balance between pin count and footprint size. The TSUM1PFR-LF is highly prevalent in the following
If the Tsum1pfr-lf includes an internal MOSFET, Pin 6 becomes the Drain/Switch node.
Operating ambient temperature range spans -40°C to 105°C .
The TSUM1PFR-LF supports LVDS (Low-Voltage Differential Signaling) panel interface formats, making it compatible with a wide range of LCD panels, from small sizes up to XGA/SXGA resolutions. 2.4 Power Management & EMI Reduction
Serves as the primary mainboard scalar for small-screen display units.
The typical system configuration for a monitor using the TSUM1PFR-LF follows this architecture:
