■ DESCRIPTION
The MB90M405 series is a general-purpose 16-bit microcontroller, developed for applications requiring fluorescent
display tube panel control. Each microcontroller is equipped with 60 highly voltage-resistant output pins, needed
for fluorescent display control. The command structure inherits the same AT architecture as the F²MC-8L and
F²MC-16L, in order to provide enhanced C-language support, improved extended/signed multiplication/division
instructions in addressing mode, and enhanced bit processing. In addition, an onboard 32-bit accumulator allows
long word processing.
