Is there a KiCad symbol and footprint for the D87C541-1?
Yes. The symbol is EasyEDA_Cloud:D87C541 and the footprint EasyEDA_Cloud:PDIP-40_L52.3-W13.8-P2.54-LS15.2-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the D87C541-1?
CDIP-40, with 40 pins. Its footprint is drawn on this page.
Where is the D87C541-1 datasheet?
AMD publishes it: the Datasheet link on this page opens it.
Where can I order the D87C541-1?
JLCPCB lists it as part C3229531, with 0 in stock; the sellers' links on this page open their listings.
What can replace the D87C541-1?
Parts like it in the library: the AT89C51RC2-3CSUM by Microchip Technology, the D87C51-1 by AMD, the IA6805E2PDW40IR0 by Analog Devices and the AT80C31X2-3CSUL by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
