    Abstract: A memory circuit for a print component including a plurality of I/O pads, including an analog pad, to connect to a plurality of signals paths which communicate operating signals to the print component, and a memory component to store memory values associated with the print component. A control circuit to, in response to identifying a sequence of operating signals representing a memory read, provide a first analog signal on the analog pad in parallel with a second analog signal from the print component to provide an analog electrical value on the analog pad representing stored memory values selected by the memory read.

    IPC: B41J2/045

    Abstract: A print component includes an array of fluidic actuation structures including a first column of fluidic actuating structures addressable by a set of actuation addresses, each fluidic actuating structure having a different one of the actuation addresses and having a fluidic architecture type, and a second column of fluidic actuating structures addressable by the set of actuation addresses. Each fluidic actuating structure of the second column has a different one of the actuation addresses and has a same fluidic architecture type as the fluidic actuating structure of the first column having the same address. An address bus communicates the set of addresses to the array of fluidic actuating structures, and a fire signal line communicates a plurality of fire pulse signal types to the array of fluidic actuating structures, the fire pulse signal type depending on the actuation address on the address bus.

    IPC: B41J2/175

    Abstract: A logic circuitry package for a replaceable print apparatus component includes an analog sensor cell block with a plurality of sensor cells, analog control circuitry to bias and control the analog sensor cell block, an interface to communicate with a print apparatus logic circuit, a dedicated bit field that indicates whether the logic circuitry package is in a power saving mode, and at least one logic circuit. The at least one logic circuit may be configured to receive, via the interface, a request to cause the analog sensor cell block to provide sensor information for at least one sensor measurement; and selectively enable and disable power to the analog control circuitry based on the request and a value of the dedicated bit field.

    IPC: B41J2/045

    Abstract: A logic circuitry package includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit. The logic circuit is configured to receive, via the interface, a plurality of first requests in a heater disabled mode, each first request corresponding to a different sensor ID of a plurality of sensor IDs; transmit, via the interface, a first digital value in response to each first request; receive, via the interface, a plurality of second requests in a heater enabled mode, each second request corresponding to a different sensor ID of the plurality of sensor IDs; and transmit, via the interface, a second digital value in response to each second request. Delta values corresponding to a difference between the first digital value and the second digital value for each different sensor ID of the plurality of sensor IDs are indicative of a print material level.
