The MB89670R/670AR series has been developed as a line of proprietary 8-bit, single-chip microcontrollers. In addition to the F2MC*-8L family CPU core which can operate at low voltage but at high speed, the microcontrollers contain pheripheral functions such as timers, a serial interface, a 10-bit A/D converter, a UART, an 8/16-bit up/down counter/timer, and an external interrupt. The MB89670R/670AR series is applicable to a wide range of applications from consumer appliances to industrial equipment, including portable devices. *: F2MC stands for FUJITSU Flexible Microcontroller.
