MB90477

■ DESCRIPTIONS

The FUJITSU MB90470 Series is a 16-bit general-purpose microcontroller designed for consumer products and other process control applications requiring high-speed and real-time processing.
The F2MC-16LX CPU core instruction set retains the AT architecture of the F2MC1 family, with additional instructions for use with high-level languages, expanded addressing mode, enhanced multiply and divide instructions, and full bit processing. Also included is a built-in 32-bit accumulator for long-word processing.
Peripheral resources built into the MB90470 series include 8/16-bit PPG, expanded I/O serial interface, UART, 10-bit A/D converter, 16-bit input-output timer, 8/16-bit up-counter, PWC timer, I2C2 interface, DTP/external interrupt, chip select, and 16-bit reload timer.
