What is the name of the chip select line?
Chip 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 called “chips”) out of several connected to the same computer bus, usually utilizing the three-state logic. One bus that uses the chip/slave select is the Serial Peripheral Interface Bus
What kind of serial interface does ICs use?
All of ICS’s Serial Interfaces provide GPIB like IEEE-488.2 functionality over an RS-232 or RS-485 Serial link and are serial devices. Click herefor our Serial to GPIB Controller.
When do you need to use chip select?
When an engineer needs to connect several devices to the same set of input wires (e.g., a computer bus), but retain the ability to send and receive data or commands to each device independently of the others on the bus, they can use a chip select.
How does a Serial Peripheral Interface ( QSPI ) work?
A Queued Serial Peripheral Interface (QSPI; see also Quad SPI) is a type of SPI controller that uses a data queue to transfer data across the SPI bus. It has a wrap-around mode allowing continuous transfers to and from the queue with only intermittent attention from the CPU.
How many chip select lines are in the EPROM?
For the EPROM, the 16 bit address can be broken into 5 chip select lines, and 11 lines for inside the EPROM 00000XXXXXXXXXXX Consider the RAM It is the same size as the EPROM, so it will also have 5 chip select lines. Calculate the multiple that corresponds to 32K (the starting location for the RAM) 32K/2K = 16
What’s the difference between chip select and SPI?
Usually chip select is an active low signal; hence, the master must send a logic 0 on this signal to select the slave. SPI is a full-duplex interface; both master and slave can send data at the same time via the MOSI and MISO lines respectively.
