#180078 - 5V has its merits... Responding to: ???'s previous message |
... namely higher noise immunity (read: works on badly designed cheapo 1- or 2-layer PCB) and higher availability and lower cost of commodity peripherals, and lower probability of damage due to "glitches" of all kinds and sorts...
See for example the LPC9xx story - some 5 years ago Bill Houghton on these very pages explained that the 3V technology is cheaper and that the developers should accomodate. Last year, NXP introduced the 5V (more precisely, wide supply voltage) LPC97x and LPC98x... which appear to be even cheaper than their 3V equivalents... JW |
