There is a Toshiba TC89121 which is a 128 X 8 serial EEPROM. The * might be shorthand for the TC8 portion of the part number. I've seen a lot of 74 series logic chips that are labeled *F04 for example where the * is for the 74 and the manufacturer's letters and the F04 actually tells you what type of logic chip it is. It doesn't appear to have a T suffix though. Also 128 X 8 seems a little small... Jeff Walther -- More likely, at least in the case of TTL logic parts, it indicates that the part is available in industrial/commercial temperature range 74xx or military temperature range 54xx. Generally part number suffixes have to do with package style, plating, etc. Often a 'T' indicates tape and reel packaging for tape and reel pick and place machines. That particular suffix is usually left off of the device, however. It is the same part number whether T&R or individually packaged. So, I suspect the "T" mentioned above refers to something else. -- SuperMacs is sponsored by <http://lowendmac.com/> and...
