MB91191 Datasheet | Fujitsu Semiconductor Limited

DESCRIPTION The MB91191/192 series is a single-chip microcontroller using a 32-bit RISC-CPU (FR series) as its core. It contains peripheral I/O resources suitable for software servo control in applications such as VTRs that require high-speed CPU processing. s FEATURES - 32-bit RISC (FR series) , load/store architecture, 5-stage pipeline - General-purpose registers : 16 × 32-bit - 16-bit fixed-length instructions (basic instructions) , 1 instruction per cycle - Includes memory-to-memory transfer, bit manipulation, and barrel shift instructions : Optimized for embedded applications - Includes function entry/exit instructions and multiple-register load/store instructions : Instruction set supports high level languages - Register interlock function : For efficient assembly language coding - Branch instructions with delay slots : Reduced overhead for branch operations - Internal multiplier unit is supported at instruction level Signed 32-bit multiplication : 5 cycles Signed 16-bit multiplication : 3 cycles - Interrupts (PC and PS saving) : 6 cycles, 16 priority levels (Continued) s PACKAGE Plastic, LQFP, 120-pin Plastic, FLGA, 144-pin (FPT-120P-M05) (LGA-144P-M02) Data Sheet 4 U . .. MB91191/192 Series Bus Interface - 16-bit address output, 8/16-bit data input and output - Basic bus cycle : 2 clock cycles - Supports interfaces for various types of memory - Multiplexed data/address input/output - Automatic wait cycles : Between 0 and 7 wait cycles can be specified independently for each memory area - Unused data/address pins can be configured as input/output ports - Supports little endian mode Bit Search Module - Searches, starting from the MSB, for the position of the first 1/0 bit transition in a word. The operation is performed in one cycle. Serial I/O - 3 channels with internal buffer RAM (automatic transfer of up to 128 bytes) - Independent send and receive buffer mode (automatic transfer of up to 64 bytes) A/D Converter (Successive Approximation Type) -...
