The IA2910A uses innovASIC’s innovative new f 3 Program to provide industry with parts that
other vendors have declared obsolete. By specifying parts through this program a customer is
assured of never having a component become obsolete again. This data sheet assumes the original
part has been designed in, and so provides a summary of capabilities only. For new designs contact
innovASIC for more detailed information.
