  • As a short intermezzo we take a look at the display which seems to have some kind of service port to gather information in case of a malfunction.

  • We flip it over, unscrew two small Phillips screws and discover the brains of this piece of modern coffee technology:

  • Renesas R5S72660W144FP 32-bit microcontroller

  • Macronix MX25L12835F 128Mb serial multi I/O NOR flash memory

  • Unisonic Technology MC34063A DC-DC converter

  • STMicroelectronics L7805CV 1.5 A voltage regulator

  • Oscillator

Comme un petit intermezzo, nous jetons un coup d'œil à l'écran, qui semble avoir une sorte de prise de communication pour extraire des informations en cas de panne.

Nous le retournons, dévissons les petites vis cruciformes et découvrons le cerveau de ce bel exemple de technologie du café moderne :

Microcontrôleur

Mémoire flash 128 Mbit multi série I/O Macronix MX25U12835F

Circuit intégré régulateur de tension à fonctions augmentation/réduction/inversion MC34063A

Oscillateur
