WebChip select ( CS) or slave select ( SS) is the name of a control line in digital electronics used to select one (or a set) of integrated circuits (commonly … WebApr 19, 2014 · 1 Answer. CE (chip enable) may also be named CS (chip select), as it is in the timing diagrams below. The others are WE (write enable) and OE (output enable). These are all active low (indicated by the overbar), but since that can't be done with ASCII characters I will use a # suffix in the text below, e.g. CS#.

If a single slave device is used, the SS pin may be fixed to logic low if the slave permits it. Some slaves require a falling edge of the chip select signal to initiate an action. An example is the Maxim MAX1242 ADC, which starts conversion o…
WebMar 14, 2024 · The final chip select logic for 1kB EPROM is illustrated below. Now, we have to generate a chip select signal for the second memory chip, which is 2kB RAM. The process is quite similar and differs from the previous one in two ways: The size of the memory is different. So, there are 11 address lines instead of 10.
