16-bit Proprietary Microcontroller
F2MC-16LX MB90350 Series
MB90F352/C(S), MB90V340(S)
The MB90350-series with one FULL-CAN interface (MB90V340: 2ch) and FLASH ROM is especially designed
for automotive and industrial applications. Its main feature is the on board CAN Interface, which conforms to V2.0
Part A and Part B, while supporting a very flexible message buffer scheme and so offering more functions than
a normal full CAN approach. With the new 0.35 µm CMOS technology, Fujitsu now offers on-chip FLASH-ROM
program memory up to 128 Kbytes. An internal voltage booster removes the necessity for a second programming
An on board voltage regulator provides 3 V to the internal MCU core. This creates a major advantage in terms
of EMI and power consumption.
The internal PLL clock frequency multiplier provides an internal 42 ns instruction cycle time from an external 4
MHz clock.
The unit features an 4 channel Output Compare Unit and 6 channel Input Capture Unit with two separate 16-bit
free running timers. 2 UARTs (MB90V340: 3 UARTs) constitute additional functionality for communication pur-
