The 16C64, as far as I understand,will be available in extended temp. Initially I think that Industrial is the one Microchip will put thru. It has -40 - +85 C as it_s limits. The one you are looking for is the "E" temp which is Automotive temprange going from -40 to +125 C and that one will be early 1995 or something. /Johan, FAE Sales Sweden
