This invention relates to a digital electronic control unit for operating domestic and commercial appliances comprising a plurality of linear and non- linear sensors (2a to 2d), analog multiplexer (3), analog to digital convertor (4), linearity offset and sensitivity correction circuit (5), central control unit (6), digital noise filter (7), digital demultiplexer (8), control latches (9a to 9f) and non-volatile memory (17). The said digital electronic control unit further includes at least one of the following at the input of the said central control unit: real-time clock (C), remote control interface (R), network interface (N). An implementation in the form of an Application Specific Integrated Circuit (ASIC) results in a miniature and cost effective control element.
La présente invention concerne une unité de commande électronique numérique permettant le fonctionnement d'appareils électrodomestiques et commerciaux, qui comprend une pluralité de capteurs linéaires et non linéaires (1a-1d), un multiplexeur analogique (3), un numériseur (4), un circuit de correction de décalage de linéarité et de sensibilité (5), une unité de commande centrale (6), un filtre numérique antiparasites (7), un démultiplexeur numérique (8), des serrures de commande (9a-9f) et une mémoire non volatile (17). La présente invention, mise en oeuvre sous la forme d'un circuit intégré spécifique (21), permet d'obtenir un élément de commande miniature rentable.
