Atmel gave an outlook on Tuesday for the fall that was one of the few cluews as to how well iPad rivals were faring in the market. It expected its touchscreen contoller chip sales to drop 12 to 16 percent, as low as $402.7 million, at a time when shipments were normally up. Some of the company's tablet customers, including Dell and Samsung, had higher than usual inventories that pointed to a lack of sales.
