YINGHUA ST7540TR Controller Processor

The YINGHUA ST7540TR is a controller and processor integrated circuit packaged in a 28-pin HTSSOP format. It serves as a semiconductor component for electronic designs requiring integrated control and processing functions. This device is supplied in new condition for use in manufacturing or development workflows.

Engineers building custom control systems

This IC suits engineers building custom control systems who need a dedicated controller processor in a 28-pin HTSSOP package. It is not intended for buyers seeking a programmable microcontroller with documented instruction sets or integrated flash memory. Designers requiring higher pin counts or alternative package styles such as QFP or BGA should evaluate other part numbers.

Questions about this item

What thermal limit appears first when the ST7540TR runs continuously in its HTSSOP-28 package?

The exposed pad on the 28-lead HTSSOP package provides the primary heat path; sustained operation will hit the junction-temperature ceiling before any other limit.

How much heat does the ST7540TR dissipate during all-day operation?

The 28-lead HTSSOP package with its exposed thermal pad is designed to conduct heat into the PCB copper, keeping temperature rise modest under typical controller workloads.
