Infineon Technologies rozširuje ponuku 8-bitových MCU v rade XC800 o dve ďalšie série: XC82x a XC83x.
Obe série obsahujú štandartné 8-bitové jadro 8051 a periférie, optimalizované pre vyššie úspory energie a nižšie náklady na implementáciu.
Niektoré MCU v týchto sériách budú obsahovať špeciality pre uľahčenie a zlepšenie návrhu uživateľských prístupov pre aplikácie s dotykovými panelmi a LED displejmi.
