Fujitsu's low-power 8bit flash MCU

Fujitsu Microelectronics America Inc. unveiled a pair of 8bit flash MCUsthe MB95F128 and MB95F168Mfor use in household appliances and digital audio/video equipment. The two MCUs are the latest addition to the F2MC-8FX family of 8bit MCU, which feature low power consumption and high performance.

The new models incorporate built-in LCD controllers, with flashing LCD displays that include hardware-based settings. These can flash each character individually, eliminating the need to control LCD flashing through software. The MCUs also have dual-use LCD power pins and display output pins that can be used as general-purpose I/O pins, so the devices can be used in other applications.

With 60Kbyte flash memory, the MB95F128 comes in a 100-pin LQFP package and runs on either 5V or 3V, making it suitable as an LCD controller for low-voltage devices such as phones and electronic blood pressure meters. The MB95F168M with 60Kbyte flash memory comes in a 64-pin LQFP package that runs at 5V, making it suitable for LCDs on microwave ovens, rice cookers, electric heaters and other appliances.

Common evaluation boards and development tools are already available for the product family, and a single evaluation environment supports development for every package. The MB95F128 is available at $4.37 each in sample quantities. The MB95F168M will be available Q2 with prices starting at $3.91 each.
