There Is A Cost To Extended Lifetime Products. It’s 7.5%.

Silicon and integrated circuits come and go, but when it comes to extended lifetime support from a company, it’s very, very hard to find fault with Microchip. They’re still selling the chip — new — that was the foundation of the Basic Stamp. That’s a part that’s being sold for twenty-five years. You can hardly find that sort of product support with a company that doesn’t deal in high-tech manufacturing.

While the good times of nearly unlimited support for products that are decades old isn’t coming to an end, it now has a cost. According to a press release from Microchip, the price of these old chips will increase. Design something with an old chip, and that part is suddenly going to cost you 7.5% more.

The complete announcement (3MB PDF), states, in part:

…in the case of extended lifecycle product offerings, manufacturing, assembly and carrying costs are increasing over time for
these mature technology products and packages. Rather than discontinue our mature product, Microchip will continue to support our
customer needs for product availability, albeit increasing the prices in line with increased cost associated with supporting mature
product lines….

For all orders received after 31 August, pricing for the products listed will be subject to an increase of 7.5%

The PDF comes with a list of all the products affected, and covers the low-end ATtinys, ATMegas, and PICs that are used in thousands of tutorials available online. The ATtiny85 is not affected, but the ATMega128 is. There are a number of PICs listed, but a short survey reveals these are low-memory parts, and you really shouldn’t be making new designs with these anyway.
