MB90455 series devices are general-purpose high-performance 16-bit micro controllers designed for process control of consumer products, which require high-speed real-time processing.
This document describes the MB90455 series, a family of general-purpose high-performance 16-bit microcontrollers designed for process control in consumer products. The architecture inherits features from the F2MC family and includes enhanced instruction sets for high-level languages, expanded addressing modes, and a 32-bit accumulator for long-word data processing.
Key peripheral resources include an 8/10-bit A/D converter, UART, multiple timers (PPG, input-output, watchdog), and an external interrupt system. The series supports various low-power consumption modes, including sleep, time-base timer, clock, and stop modes, making it suitable for battery-operated devices.
| Architecture | 16-bit microcontroller |
|---|---|
| Process | CMOS technology |
| Package | 48-pin plastic-LQFP |
| Operating Voltage | 3.5V to 5.5V |
| Instruction Execution Time | 62.5 ns |
| A/D Converter | 8/10-bit, 8 channels |
| Interrupt Levels | 8 levels |
