The MB89850R series has been developed as a general-purpose version of the F2 MC*-8L family consisting of proprietary 8-bit, single-chip microcontrollers.
In addition to the F2 MC-8L CPU core which can operate at low voltage but at high speed, the microcontrollers 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 MB89850R series is applicable to a wide range of applications from consumer products to industrial equipment, including portable devices.
*: F2 MC stands for FUJITSU Flexible Microcontroller.
MB89855R Features
* Various package options SDIP package (64 pins)/QFP package (64 pins) * High-speed processing at low voltage Minimum execution time: 0.4 m s/3.5 V, 0.8 m s/2.7 V
