 +2 Good Answer/Helpful		 #188834 - Power MOSFET drive and 5V ADC
Responding to: ???'s previous message
There are plenty of reasons to choose 5V - most Automotive suppliers grasp this.
We need to properly drive Power MOSFETs, and read 5V Sensors.
- Very simple with a 5V part, but a royal pain from 3v3.

Nuvoton have 5V 32 bit parts, Fujitsu have 5V 32 bit parts, Atmel have a couple of 5V 32 bit parts, the new Renesas RX200 & RX100 are all 5V
(1.62-5.5V)....

That makes a 3.3V-only part look like a Dinosaur, and certainly NOT going to make much traction into 8 bit sockets...
Given many other vendors understand this, NXP look out of touch here.

NXP stated aim, "to make 8-bit architectures obsolete"            01/01/70 00:00      
   Available in DIP!            01/01/70 00:00      
      no continuity            01/01/70 00:00      
         It gets worse.            01/01/70 00:00      
            We need a small package            01/01/70 00:00      
               Not small enough            01/01/70 00:00      
                  Funny, that!            01/01/70 00:00      
                     Nice size, shame about price            01/01/70 00:00      
            Poor NXP, XMC1000 series announced            01/01/70 00:00      
   No 5V option            01/01/70 00:00      
      just curious            01/01/70 00:00      
         Because it is useful.            01/01/70 00:00      
         RE: why the 5V fascination?             01/01/70 00:00      
            well, you will have to redesign anyhow.            01/01/70 00:00

         5V can be surprisingly useful            01/01/70 00:00      
            Most Automotive parts DO use 5V            01/01/70 00:00      
            why?            01/01/70 00:00      
               Close, but no Cigar...            01/01/70 00:00

                     Silabs 6V ports for Class D audio            01/01/70 00:00      
                     which means they were thinking about logic-level MOSFET driv            01/01/70 00:00      
                        I was looking for something like this            01/01/70 00:00      
                           isn't it a pity ..            01/01/70 00:00      
                              this            01/01/70 00:00      
                                 but that is ~15 bucks :)            01/01/70 00:00      
                                    for one off            01/01/70 00:00

                                       What??? Which SiLabs clocks at >168E6?            01/01/70 00:00      
                                          he means higher than 80Mhz            01/01/70 00:00      
                           just wait            01/01/70 00:00

               More than 5V tolerant inputs            01/01/70 00:00      
   yeah and your problem is?            01/01/70 00:00
