Microchip’s innovative Migratable Memory technology (MMT) provides socket and software compatibility among all of its equivalent one-time-programmable (OTP), FLASH memory and ROM MCUs. MMT allows customers to match the selection of MCU memory technology to the product life cycle of their application, providing an easy migration path to a lower cost solution whenever appropriate. FLASH memory is an ideal solution for engineers designing products for embedded systems – especially during the development and early stages of the product. In certain products and applications, FLASH memory may be used for the life of the product because of the advantages of field upgradability or where product inventory flexibility is required. Once the design enters the pre-production stage and continues through introduction and growth stages, OTP program memory provides maximum programming flexibility and minimum inventory scrappage. The OTP device is pin and socket compatible with the FLASH device – providing a lower cost, high-volume flexible solution. As the design enters a mature stage and program code stabilizes, a lower cost, socket compatible ROM memory device could be used. In most cases, OTP memory may still be used as the most cost-effective memory technology for the product.
