DESCRIPTION
The FUJITSU FR family of single-chip microcontrollers using a 32-bit high-performance RISC CPU, with a variety
of built-in I/O resources and bus control mechanisms for built-in control applications requiring high-capability,
high-speed CPU processing. External bus access is assumed in order to support the expanded address space
accessible by the 32-bit CPU, and a 1 KB cache memory plus large 128 KB RAM are provided for high-speed
execution of CPU instructions.
This microcontroller is ideal for built-in applications such as DVD players, navigation systems, high-capability FAX
and printer control that demand high-capability CPU processing power.
The MB91307B is a FR65E series product based on the FR30/40 series CPU with enhanced bus access for
higher speed operation.
