We can Unlock Microprocessor IC Fujitsu MB90F867ES, please view the chip features for your reference:

 

DESCRIPTION

MB90860E-series with Flash ROM is especially designed for automotive and other industrial applications. With

the new 0.35 µm CMOS technology, Fujitsu now offers on-chip Flash ROM program memory up to 512 Kbytes.

The power supply (3 V) is supplied to the internal MCU core from an internal regulator circuit. 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 8 channel Output Compare Unit and 8 channel Input Capture Unit with 2 separate 16-bit free

running timers. 4 UARTs constitute additional functionality for communication purposes.

Note : F2MC is the abbreviation of FUJITSU Flexible Microcontroller.
