Description

The MB89T855 series has been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit, single-chip, microcontrollers.

In addition to the F2MC-8L CPU core which can operate at low voltage but at high speed, the MB89T855 contain a variety of peripheral functions such as a timer unit, PWM timers, a UART, a serial interface, a 10-bit
A/D converter, and an external interrupt.

The MB89T855 series is applicable to a wide range of applications from welfare products to industrial equipment, including portable devices.

*: F2MC stands for FUJITSU Flexible Microcontroller.
