MB90F867AS Datasheet PDF - Fujitsu

●■

●DESCRIPTION

●The MB90860A-series is Fujitsu 16-bit general-purpose microcontroller which enhances each kind of timers and communication macros. With the new 0.35 µm CMOS technology, Fujitsu now offers 128 Kbytes on-chip FLASH ROM program memory. An internal voltage booster removes the necessity for a second programming voltage.
