F2MC-16LX MB90330A Series
MB90333A/F334A/MB90V330A
■ DESCRIPTION
The MB90330A series are 16-bit microcontrollers designed for applications, such as personal computer peripheral
devices, that require USB communications. The USB feature supports not only 12-Mbps Function operation but
also Mini-HOST operation. It is equipped with functions that are suitable for personal computer peripheral devices
such as displays and audio devices, and control of mobile devices that support USB communications. While
inheriting the AT architecture of the F2MC family, the instruction set supports the C language and extended
addressing modes and contains enhanced signed multiplication and division instructions as well as a substantial
collection of improved bit manipulation instructions. In addition, long word processing is now available by intro-
ducing a 32-bit accumulator.
Note : F2MC is the abbreviation of FUJITSU Flexible Microcontroller.
