In this market, microcontroller lead times are longer than development time to market. The edge on new designs is going to products we already have in the pipeline or vendors (like Microchip at 8 - 12 weeks) who can get the standard product out in volumes.
If you can get an ARM inside an MCU of many manufacturers -vendor independence-, with all technical flavors about capabilities, peripherals, performance, tools and most important, a huge ecosystem, why would you turn to RX which seems unknown? I see the biggest issue for Renesas to succeed in the MCU arena from now on, to make their chips much more popular, which is something that will not happen overnight.
It drastically makes non sense to stop the supporting for old Renesas and NEC products as it is no difference to pushing customers out of door. You can invest little on the legacy but not that for support. That is of essentical ethic but not only strategy. And it is not seldom to see such illustrations. for examples, 51x, for some MCU companies, as been major products for last decades and now faded natually and smoothly. It can coexist with other overlaped lines for some years in the same company. For RX, even they make big inroad, typically there will be some years for customers to accepy a new architecture.
Renesas has to stop supporting other products. if you combine the operation and support all.. it means you get the sales and losses same as you take them as individual company. Thats easy to figure out. About RX. the question is how can they popularize their compiler, tools..etc.. and entice the people to change to such proprietary tool.. if they did their previous way of cutting the chip price too low to kick out some supplier, they wont have good profit too..
I believe you catch the wrong persen for the ad of steam. I also sight the intruder who should have been cleaned. Anyway, It will be intresting if you can also share your comments here on this thread. :)
Even the new Renesas prdges to mentain/support the old Renesas and NEC lines, None-roadmap is the only doom for legacy produts as no more R&D resources allocated. You need to wait for several years for the full RX lineup. In the interim of Renases' reorganization, his rivals are honing their swords. 2010 is a blow-out year. But who lose this year will loosen in further future.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
