Tekmos has announced the qualification and release of two of our microcontrollers, the TK68HC711D3 and TK68HC11D0. The micros were originally made at our provider Plessey Semiconductor. Plessey closed their 0.35u fab, and the designs were transferred to the X-Fab foundry located in Dresden, Germany. Originally each design had its own mask set. This reflected the fact that the parts were designed at separate times. When the designs were transferred to Dresden, the designs were merged onto a common substrate die. The new die was designed to support an optional Flash memory, which could be enabled through bond options.
There are no changes to the operation of either circuit, and each chip remains a drop-in replacement for the original NXP parts.
Having a drop-in replacement for parts has shown to be a very cost effective way to extend the life of products when the original component manufacturer discontinues a part. The availability of a drop-in replacement part eliminates the need to make the tough decision whether to redesign a printed circuit board or discontinue a product.
Tekmos continues to be the "go to" supplier when there are problems finding obsolete parts or when additional parts are needed after the date for EOL (End of Life) purchase has passed. Tekmos makes a variety of microcontrollers, microprocessors, and other miscellaneous standard products to satisfy these needs. Tekmos also continues to make custom ASIC replacement parts.
Customers are aware that buying from Tekmos ensures pin for pin, drop-in replacements that can be counted on to work in their applications, without worry about the quality of parts purchased on the grey market.
