Semiconductor IC in 128-LQFP Package

The YINGHUA AT91SAM7SE32B-AU is a semiconductor integrated circuit supplied in a 128-LQFP package. It is intended for engineers and developers building embedded systems that require this specific microcontroller. The component is listed as new and was first recorded by the manufacturer on February 21, 2025.

Designers Needing This Exact Part Number

This device suits designers who must source the AT91SAM7SE32B-AU for a qualified bill of materials or an existing board layout. Buyers who need a different pin count, package style, or flash size should look elsewhere because this item is fixed at the 128-LQFP configuration.

128-Pin LQFP Footprint Dictates PCB Layout

The 128-LQFP package defines the physical footprint and pin assignment for the printed circuit board. Verifying that the board design matches this exact package is the single specification that determines whether the component can be used.

Questions about this item

How do I solder the 128-LQFP package without bridging pins?

Use a fine-tip iron with flux, tack opposite corners first, then drag-solder each side; inspect every row under magnification before powering up.

What long-term care does the AT91SAM7SE32B-AU require?

Keep the chip within its rated temperature range, avoid static discharge during handling, and verify solder joints remain intact after thermal cycling.

Which limit appears first during continuous operation?

The 128-pin LQFP thermal envelope typically saturates before the internal logic hits its maximum clock, so sustained loads demand adequate PCB copper or airflow.
