s DESCRIPTION
This model, designed on the basis of 32-bit RISC CPU (FR30 series), is a standard single-chip micro controller
with built-in I/O resources and bus control functions. The functions are suitable for built-in control that requires
high-speed CPU processing.
MB91F127 includes 256 Kbytes built-in flash memory and 14 Kbytes built-in RAM. MB91F128 includes 510 Kbytes
built-in flash memory and 14 Kbytes built-in RAM.
The specifications of the devices are best suited for applications requiring high-level CPU processing capabilities,
such as navigation system, high-performance FAX, and printer controller.
