MB91F355A Overview
Description
The FR families are lines of standard single-chip microcontrollers each based on a 32-bit high-performance RISC CPU, incorporating a variety of I/O resources and bus control features for embedded control applications which require high CPU performance for This FR60 family is based on FR30 and FR40 families and enhanced is bus access. The FR60 family is a line of single-chip oriented microcontrollers incorporating a wealth of peripheral resources.
Key Features
- Instructions adapted for high-level languages: Function entry/exit instructions, multiple-register load/store instructions (Continued)
- Register interlock functions: Facilitating coding in assemblers
- On-chip multiplier supported at the instruction level. Signed 32-bit multiplication: 5 cycles. Signed 16-bit multiplication: 3 cycles
- Interrupt (PC, PS save): 6 cycles, 16 priority levels
- Harvard architecture allowing program
