Title
(EN) LOGIC CIRCUITRY PACKAGE
(FR) BOÎTIER DE CIRCUIT LOGIQUE
Abstract
(EN)
A logic circuitry package for a replaceable print apparatus component includes a first at least one analog cell of a first type, a second at least one analog cell of a second type, an analog-digital converter (ADC), 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, requests to perform measurements to selected ones of the at least one first and second analog cells. The at least one logic circuit is configured to selectively route analog signals from the selected analog cells to the ADC based on the requests.

Cette invention concerne un boîtier de circuit logique pour un composant d'appareil d'impression remplaçable, comprenant au moins une première cellule analogique d'un premier type, au moins une seconde cellule analogique d'un second type, un convertisseur analogique-numérique (CAN), une interface pour communiquer avec un circuit logique d'appareil d'impression, et au moins un circuit logique. Le(s) circuit(s) logique(s) est/sont configuré(s) pour recevoir, par l'intermédiaire de l'interface, des demandes pour effectuer des mesures sur des cellules sélectionnées parmi la/les première(s) et seconde(s) cellules analogiques. Le(s) circuit(s) logique(s) est/sont configuré(s) pour acheminer sélectivement des signaux analogiques des cellules analogiques sélectionnées au convertisseur analogique-numérique sur la base des demandes.
