Applications
AT89LP428-20PU is sourced for OEM/EMS electronic assemblies. Typical use depends on the manufacturer datasheet for Microchip Technology. Confirm electrical ratings, PDIP-28 mechanics, and AVL notes before design-in or substitution. SJ Chip provides inventory checks and RFQ support for production and shortage fills.
Procurement notes
Confirm the full ordering code, package (PDIP-28), and quantity on RFQ. SJ Chip replies with stock, condition, and lead time. Nearby MPNs are for evaluation only.

FAQ
Where to buy AT89LP428-20PU?
You can request AT89LP428-20PU from SJ Chip via the RFQ form on this page or the site-wide RFQ. We confirm manufacturer (Microchip Technology), package, quantity, and lead time on the quotation.
Is AT89LP428-20PU available?
Listed inventory shows 5,000 pcs. Lot, date code, and shippable quantity are confirmed on RFQ — treat the listing as availability to quote, not a guaranteed cart ship.
What is the package of AT89LP428-20PU?
The sourcing listing shows package PDIP-28. Always verify body size, pitch, and land pattern against the Microchip Technology datasheet before PCB layout.
What are alternatives to AT89LP428-20PU?
Potential alternatives include AT89LP428-20JU, AT89LP428-20MH, AT89LP4052-20SUR and other same-series or same-package listings — all require datasheet and pinout checks. These are similar stock for evaluation, not automatic drop-in replacements.
