Handheld PCs, PDAs and smart cell phones are showing up in new applications every day. These new products are made possible by the adoption of wireless technology and the internet. Taxi and delivery services, vendors at fairs and swap meets and many other mobile merchants are now able to accept credit cards in the field.
Semtek Corp, a San Diego based company that manufactures credit card readers, was developing a new product. “Our new reader had to be small, very low power and low cost,” remarked Dennis Mos, VP Sales and Marketing at Semtek.
Size, power and cost are all benefits of ASIC technology; however, developing an ASIC, particularly a Mixed Signal ASIC, can be expensive and time consuming. Such an undertaking may prove especially risky for new product like Semtek’s wireless credit card reader. Many engineering managers are of the mind that ASIC’s are best left to the “Big Boys.” And considering the high cost of tools, masks and fabrication they are probably correct, but not completely.
