Brown-Out Reset – an Update Break Points 7/8/2014 2 comments When using brown-out reset circuits, the bottom line is that on many MCUs you can’t use the A/D to monitor Vdd during flash writes unless there’s some way to simulate the expected load. As always, do a careful, worst-case engineering analysis.
Fifty Years of TTL Break Points 6/25/2014 26 comments Depending on your source, 2014 marks the 50th anniversary of TTL (transistor-transistor logic). Although some say 1961 is the birth year, TI released the 5400 family in 1964 and the 7400 series in plastic two years later.
