Is there a KiCad symbol and footprint for the AT89LP51ED2-20PU?
Yes. The symbol is EasyEDA_Cloud:AT89LP51ED2-20PU_C613533 and the footprint Package_DIP:DIP-40_W25.4mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AT89LP51ED2-20PU?
PDIP-40, with 40 pins. Its footprint is drawn on this page.
Where is the AT89LP51ED2-20PU datasheet?
Microchip Technology publishes it: the Datasheet link on this page opens it.
Where can I order the AT89LP51ED2-20PU?
JLCPCB lists it as part C613533, with 10 in stock; the sellers' links on this page open their listings.
What can replace the AT89LP51ED2-20PU?
Parts like it in the library: the STC89C516RD+40I-PDIP40 by STC Micro, the STC89C52RC-40I-PDIP40 by STC, the AT89S52-24PU by Microchip Technology and the PIC18F45K80-I/P by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
