■ DESCRIPTION
The MB90520B series is a general-purpose 16-bit microcontroller designed for process control applications in
consumer products that require high-speed real-time processing.
The microcontroller instruction set is based on the AT architecture of the F²MC* family with additional instructions
for high-level languages, extended addressing modes, enhanced multiplication and division instructions, and a
complete range of bit manipulation instructions. The microcontroller has a 32-bit accumulator for processing long
word (32-bit) data.
The MB90520B series peripheral resources include an 8/10-bit A/D converter, 8-bit D/A converter, UART (SCI) ,
extended I/O serial interfaces 0 and 1, 8/16-bit up/down counter/timers 0 and 1, 8/16-bit PPG timers 0 and 1, a range
of I/O timers (16-bit free-run timers 1 and 2, input capture (ICU) 0 and 1, and output compare (OCU) 0 and 1) , an LCD
controller/driver, 8 external interrupt inputs, and 8 wakeup interrupts.
* : F²MC is the abbreviation of FUJITSU Flexible Microcontroller.
■ FEATURES
• Clock
• Internal PLL clock multiplication circuit
• Selectable machine clock (PLL clock) : Base oscillation divided by two or multiplied by one to four
(For a 4 MHz base oscillation, the machine clock range is 4 MHz to 16 MHz) .
