The MB90335 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 introducing a 32-bit accumulator. : F2MC stands for FUJITSU Flexible Microcontroller, a registered trademark of FUJITSU LIMITED.

Clock Built-in oscillation circuit and PLL clock frequency multiplication circuit Oscillation clock The main clock is the oscillation clock divided into 2 (for oscillation 6 MHz : 3 MHz) Clock for USB is 48 MHz Machine clock frequency of 6 MHz, 12 MHz or 24 MHz selectable Minimum execution time of instruction ns (6 MHz oscillation clock, 4-time multiplied : machine clock 24 MHz and at operating VCC = 3.3 V) The maximum memory space:16 MB 24-bit addressing Bank addressing
