We had a feeling that Freescale was onto something when it debuted the i.MX508, a system-on-a-chip that carried the promise of $150 e-readers (and the reality of $129 ones). Given that, we can see where the execs at Freescale would be feeling a bit heady, and might wonder where else they could help push down prices. That's exactly what we have here: the outfit is trotting out three new i.MX50 processors and, as you can see in that handy chart up there, they all sit even lower in the lineup than the low-cost i.MX508. Like the i.MX508, they all pack an 800HMz ARM Cortex-A8 processor, among other similar specs. The new i.MX507, in particular, resembles the i.MX508 in that it's designed to work with E Ink displays, though it lacks graphics acceleration, and Freescale imagines it'll instead find a home in outdoor signs and smart labels. Moving on down the line, the i.MX502 and the i.MX503 were both intended for devices with LCD -- not electronic paper -- displays, with the latter offering OpenVG graphics acceleration. If Freescale's predictions are on the money, you'll find the lower-end i.MX502 in DECT phones and vending machine displays, and the i.MX503 in personal navigators and medical monitoring tablets, among other use cases. For now, companies are sampling the chips, but they'll start shipping later this quarter for a song -- less than $10 for the i.MX502 at volume cost.
