    Abstract: In an example, a logic circuitry package is configured to communicate with a print apparatus logic circuit. The logic circuitry package may be configured to respond to communications sent to a first address and to at least one second address. The logic circuitry package may comprise a first logic circuit, wherein the first address is an address for the first logic circuit. The package may be configured such that, in response to a first command indicative of a task and a first time period sent to the first address, the package is accessible via at least one second address for a duration of the time period.

    Abstract: A replaceable print apparatus component includes a print material reservoir, a print material within the reservoir and a sensing system including an integrated circuit configured to connect to and communicate over a digital bus. The sensing system includes at least one sensor, a digital controller, an analog to digital converter electrically coupled to the digital controller, and a memory array electrically coupled to the digital controller. The digital controller is configured to generate a clock signal for timing operations of the integrated circuit. The operations include initiating the at least one sensor based on values stored in the memory array and generating outputs of the at least one sensor via the analog to digital converter.

    Abstract: A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit. The at least one logic circuit is configured to receive, via the interface, a request and a reference clock signal. The at least one logic circuit is configured to transmit, via the interface, a digital value indicating a count in response to the request and the reference clock signal. The digital value varies based on the reference clock signal.

    IPC: B41J2/045

    Abstract: An integrated circuit to drive a plurality of fluid actuation devices includes a plurality of memory cells, a select circuit, configuration logic, and control logic. Each memory cell corresponds to a fluid actuation device. The select circuit selects fluid actuation devices and memory cells corresponding to the selected fluid actuation devices. The configuration logic enables or disables access to the plurality of memory cells. The control logic either activates the selected fluid actuation devices or accesses the memory cells corresponding to the selected fluid actuation devices based on a state of the configuration logic.

    Abstract: An integrated circuit to drive a plurality of actuators during a non-reset operating condition is disclosed. The integrated circuit includes a reset input to receive a reset signal activated for a duration. The reset signal generates a reset condition in the integrated circuit during which the non-reset operating condition is blocked. The integrated circuit also includes a monitor circuit operably coupled to the reset input to indicate if the duration of the reset signal meets or exceeds a selected duration.

    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.
