The MB90460 series is a line of general-purpose, Fujitsu 16-bit microcontrollers designed for process control applications which require high-speed real-time processing, such as consumer products. While inheriting the AT architecture of the F2MC* family, the instruction set for the F2MC-16LX CPU core of the MB90460 series incorporates additional instructions for high-level languages, supports extended addressing modes, and contains enhanced multiplication and division instructions as well as a substantial collection of improved bit manipulation instructions. In addition, the MB90460 has an on-chip 32-bit accumulator which enables processing of long-word data. The peripheral resources integrated in the MB90460 series include : an 8/10-bit A/D converter, UARTs (SCI) 0 to 1, 16-bit PPG timer, a multi-functional timer (16-bit free-run timer, input capture units (ICUs) 0 to 3, output compare units (OCUs) 0 and 5, 16-bit PPG timer, a waveform generator), a multi-pulse generator (16-bit PPG timer, 16-bit reload timer, waveform sequencer), PWC 0 to 1, 16-bit reload timer and DTP/external interrupt.
The MB90460 series is a line of general‑purpose 16‑bit microcontrollers from Fujitsu Semiconductor, aimed at process‑control and consumer‑product applications that need high‑speed real‑time processing. The devices inherit the AT architecture of the F?MC family and add instructions for high‑level languages, extended addressing modes, and a 32‑bit accumulator for long‑word data.
The handbook details the integrated peripherals (8/10‑bit A/D converter, UARTs, multiple timers, PWM, and more), package options (64‑pin QFP, LQFP, SH‑DIP), pin assignments, and electrical characteristics such as power‑supply range and execution timing. It also lists memory sizes, instruction counts, and low‑power modes.
