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. Note : F2MC stands for FUJITSU Flexible MicroController, and is a registered trademark of Fujitsu Limited. ■ FEATURES Clock Internal PLL clock multiplication circuit Oscillation clock 1/2 main oscillation clock 1 × to 4 × PLL oscillation clock (2 MHz to 16 MHz at 4 MHz oscillation) , can be set from machine clock Minimum instruction execution time : 62.5 ns (operating at 4 MHz oscillation, 4 × PLL clock, VCC = 3 V) Oscillation clock can generate 1/32, 1/64, 1/128, and 1/256 external clock outputs.
