    Abstract: A data storage device and method for lane detection and configuration are provided. In one embodiment, a data storage device is provided comprising a memory, an interface, and a controller. The controller is configured to detect whether a cable coupled with the interface is providing a first channel configuration signal that indicates that the cable is in a first cable orientation or a second channel configuration signal that indicates that the cable is in a second cable orientation. In response to detecting that the cable is not providing either the first or the second channel configuration signal, the controller uses a default lane configuration to communicate with the host via the cable. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

  • Patent number: 11907154
    Abstract: A receive clock generated at a receiver coupled to a one-wire bus is synchronized in each clock cycle, permitting reception of a data frame of unlimited length without clock overrun or underrun. A base clock signal provided by an oscillator is passed by a clock gating circuit while the clock gating circuit is enabled. A counter counts positive and negative edges in an output of the clock gating circuit. The clock gating circuit is disabled when an output of the counter indicates a preconfigured maximum count value. An edge synchronization circuit that synchronizes edges in the base clock signal with edges in a data signal received over the one-wire bus ignores edges in the data signal while the counter output has a value that is less than the maximum count value, and resets the counter in response to an edge detected in the data signal received over the one-wire bus.

  • Patent number: 11868300
    Abstract: A chiplet system can include a Serial Peripheral Interface (SPI) bus for communication. A primary device coupled to the SPI bus can generate read or write instructions for a secondary device. In response to instructions from the primary device, the secondary device can prepare a response. The response message can include a secondary device status field to indicate a readiness of the secondary device to provide a particular data payload to the primary device. Using deferrals that are communicated from the secondary device to the primary device can enable longer latency SPI operations to proceed without monopolizing the SPI bus.

  • Patent number: 11868293
    Abstract: A device for a serial bus system. The device includes a reception block for receiving a signal from a bus of the bus system. The signal is based on a transmission signal via which a message is exchanged between user stations. The reception block receives, in a first communication phase, the signal using a first reception threshold, and in a second communication phase, receives the signal using a second reception threshold. The device includes an evaluation block for evaluating the signal from the bus using a switchover reception threshold that differs from the first and second reception thresholds, and a reception threshold switching block for the time-limited switchover of the reception threshold of the reception block from the first reception threshold to the second reception threshold when the evaluation block detects the bus level for data of the transmission signal, using the switchover reception threshold in the signal.

  • Patent number: 11853251
    Abstract: Disclosed are techniques for chip-to-chip (C2C) serial communications, such as communications between chiplets on a multi-chip package. In some aspects, a method of on-die monitoring of C2C links comprises detecting a change of the C2C link from a first link state to a second link state and storing link state change information in an on-die first-in, first-out (FIFO) buffer. The link state change information indicates the first link state, the duration of time the C2C link was in the first link state, and the speed of the C2C link in the first link state. Upon detecting a request for link state change information, link state change information is retrieved from the FIFO buffer and transmitted serially to an output pin of the die, such as a general purpose input/output (GPIO) pin.

  • Patent number: 11847087
    Abstract: Systems and methods for chip operation using serial peripheral interface (SPI) with reduced pin options contemplate eliminating the chip select pins, interrupt pins and/or reset pins for host (also referred to as master)-to-device (also referred to as slave) communication links, while preserving the possibility of backward compatibility for legacy devices if desired. The communication link may include a clock line, a host-to-device line, and a device-to-host line. The host may use specific sequences of signals on the clock and host-to-device line to provide start and stop sequence commands, interrupts, or reset commands. By consolidating these commands onto the clock and host-to-device line, pin count may be reduced for portions of the host and slave circuits. Likewise, fewer (or at least shorter potentially) conductive traces may be needed to interconnect the host to the device. Such changes may save cost, make layout design easier, and/or save space within a computing device.
