■ DESCRIPTIONS
The FUJITSU MICROELECTRONICS MB90420G/425G Series is a 16-bit general purpose high-capacity micro-
controller designed for vehicle meter control applications etc.
The instruction set retains the same AT architecture as the FUJITSU MICROELECTRONICS original F²MC-8L
and F²MC-16L series, with further refinements including high-level language instructions, expanded addressing
mode, enhanced (signed) multipler-divider computation and bit processing.
In addition, a 32-bit accumulator is built in to enable long word processing.
■ FEATURES
• 16-bit input capture (4 channels)
Detects rising, falling, or both edges.
16-bit capture register × 4
Pin input edge detection latches the 16-bit free-run timer counter value, and generates an interrupt request.
• 16-bit reload timer (2 channels)
16-bit reload timer operation (select toggle output or one-shot output)
Event count function selection provided
• Watch timer (main clock)
Operates directly from oscillator clock.
Compensates for oscillator deviation
Read/write enabled second/minute/hour register
Signal interrupt
