CUSTOMER ADVISORY EP9XX & EP18XX ORDERING CODE CHANGE In December of 1995, Altera announced ordering code changes in its Classic EP6XX component line. In keeping with this strategy, we are now consolidating selected EP9XX and EP18XX ordering codes (Table 1 lists the ordering codes affected under this consolidation). Please note that the substitute ordering codes are functional and pin-compatible replacements for all affected ordering codes. Altera will continue to accept orders for the current EP9XX ordering codes until September 30, 1996. Final shipments of the existing codes by Altera will occur on or before December 31, 1996. For the EP18XX product line, Altera will continue to accept orders for the current ordering codes until March 31, 1997. Final shipments of the existing codes by Altera will occur on or before June 30, 1997. Should you need additional information or assistance, please contact your local Altera sales representative. Your cooperation is greatly appreciated.
