The IA16450 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 advanced information 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.
