FUJITSU 32-bit Proprietary Microcontroller CMOS FR60Lite MB91270/280 Series MB91F272/F272S/V280 handbook
Datasheet
MB91270/280 is a single chip microcontroller based on a 32-bit high-efficiency RISC CPU, which is used for building various I/O resources and bus control mechanisms to meet the needs of embedded control with high performance/high speed CPU processing. Because the vast address space that 32-bit CPU accesses is supported, the external bus access is basically. To speed up CPU instruction execution, MB91270/280 has built-in RAM of 16 Kbytes (for data) . It is best specification for the embedded usage in which efficient CPU processing power such as the digital video camera, navigation systems, and DVD players is demanded. The MB91270/280 series power-up the bus access based on FR30/40 family CPU, and is FR60 Lite family corresponding to use at high speed.
