re: The 8051 is over 30 years old and still going strong

NO RATINGS
I know it occupies a fond place in many hearts but I have to say that the 8051 was the most horrible thing to program I have come across in 25 years. I did at least two projects with it (a bitbus comms systems for a radio switch and the control processor for a DECT cordless phone spring to mind). I, for one, would be glad to see it consigned to the museum! The 68HC11 was much nicer :-) And, yes, a dual-core Cortex-A9 woudl be overkill for a keycard reader but a Cortex-M0 or M3 would probably fit the bill really nicely! Chris

Another old warhorse that's still going strong is the HC11 family, based on Motorola 6800 (now Freescale). After all, putting a dual core ARM Cortex-A9 in a keycard reader is overkill ... :)

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
