Product Summary
The MB90487A is a 16-bit general-purpose FUJITSU microcontroller. The MB90487A is designed for process control in consumer devices and other applications requiring high-speed real-time processing. The F2MC-16LX CPU core instruction set retains the AT architecture of the F2MC*1 family, with additional instructions for high-level languages, expanded addressing mode, enhanced multiply-drive instructions, and complete bit processing. In addition, a 32-bit accumulator is provided to enable long-word processing.
