  2. Routing (electronic design automation) - Wikipedia

    en.wikipedia.org/wiki/Routing_(electronic_design...

    In electronic design, wire routing, commonly called simply routing, is a step in the design of printed circuit boards (PCBs) and integrated circuits (ICs). It builds on a preceding step, called placement , which determines the location of each active element of an IC or component on a PCB.

  3. Place and route - Wikipedia

    en.wikipedia.org/wiki/Place_and_route

    The design of a printed circuit board comes after the creation of a schematic and generation of a netlist. The generated netlist is then read into a layout tool and associated with the footprints of the devices from a library. Placing and routing the devices can now start. [1] Placing and routing is generally done in two steps.

  4. STM32 - Wikipedia

    en.wikipedia.org/wiki/STM32

    The STM32 F4-series is the first group of STM32 microcontrollers based on the ARM Cortex-M4F core. The F4-series is also the first STM32 series to have DSP and floating-point instructions. The F4 is pin-to-pin compatible with the STM32 F2-series and adds higher clock speed, 64 KB CCM static RAM, full-duplex I²S, improved real-time clock, and ...

  5. I3C (bus) - Wikipedia

    en.wikipedia.org/wiki/I3C_(bus)

    Short for Improved Inter-Integrated Circuit, [4] the standard defines the electrical connection between the chips to be a two wire, shared , serial data bus, one wire (SCL) being used as a clock to define the sampling times, the other wire (SDA) being used as a data line whose voltage can be sampled. The standard defines a signaling protocol in ...

  6. Serial Peripheral Interface - Wikipedia

    This configuration only requires a single CS line from the main, rather than a separate CS line for each sub. [ 7 ] In addition to using SPI-specific subs, daisy-chained SPI can include discrete shift registers for more pins of inputs (e.g. using the parallel-in serial-out 74 xx165) [ 8 ] or outputs (e.g. using the serial-in parallel-out 74 ...

  7. General-purpose input/output - Wikipedia

    en.wikipedia.org/wiki/General-purpose_input/output

    Integrated circuit GPIOs are commonly used to control or monitor other circuitry (including other ICs) on a board. Examples of this include enabling and disabling the operation of (or power to) other circuitry, reading the states of on-board switches and configuration shunts, and driving light-emitting diode (LED) status indicators. In the ...

  8. CAN bus - Wikipedia

    en.wikipedia.org/wiki/CAN_bus

    In this configuration a dominant state is asserted by one or more transmitters switching the CAN− to supply 0 V and (simultaneously) switching CAN+ to the +5 V bus voltage thereby forming a current path through the resistors that terminate the bus. As such the terminating resistors form an essential component of the signaling system, and are ...

  9. Circuit switching - Wikipedia

    en.wikipedia.org/wiki/Circuit_switching

    Packet switching can be based on connection-oriented communication or connection-less communication. That is, based on virtual circuits or datagrams. Virtual circuits use packet switching technology that emulates circuit switching, in the sense that the connection is established before any packets are transferred, and packets are delivered in ...
