This data sheet introduces the features of the F2MC-16LX MB90520A/520B series 16-bit proprietary microcontrollers
The MB90520A/520B series is a general-purpose 16-bit microcontroller based on the F2MC* family architecture. It features a 32-bit accumulator, an instruction set optimized for high-level languages and multi-tasking, and supports various peripheral resources including A/D converters, UARTs, timers, and LCD controllers.
The minimum instruction execution time is 62.5 ns when using a 4 MHz oscillation, PLL clock setting of x4, and VCC of 5.0 V.
The minimum conversion time is 10.2 ms when operating with a 16 MHz machine clock.
The minimum interrupt processing time is 1.5 ms when operating with a 16 MHz machine clock.
