Mesin Cuci Samsung WF8590NHW sebagai sebuah sistem embedded

Berikut ini mesin cuci WF8590NHW  dengan spesifikasi sangat sederhana: ” Top-Load dengan Diamond Drum – 6 Kg”. Sama sekali tidak disebut kemampuan prosesornya. Kalau dibongkar di dalamnya, terlihat sistem embedded di dalamnya menggunakan prosesor tipe TMP91FU62DFG. Prosesor tersebut memiliki kemampuan clock maksimum 20 MHz, ROM: 96K bytes (Flash ROM), RAM: 4K bytes.

Berikut ini papan rangkaian pengendali mesin cuci tersebut. Ukuran papan rangkaian adalah panjang 26 cm, lebar 10 cm. Posisi papan rangkaian ini tepat di belakang panel. Pada papan rangkaian terlihat LED 7 segment di bagian kiri atas, LED ini sama dengan yang nampak di bagian atas depan mesin cuci.

Berikut ini tampilan panel atas yang terletak tepat di depan papan rangkaian tersebut.
