MB91352APMT

32-bit Microcontroller

Fujitsu 

MB91350A Series

• 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 access and data access to be executed simultaneously

• Instructions compatible with the FR family

2. Bus interface

• Maximum operating frequency : 25 MHz

• 24-bit address full output (16 Mbyte address space) capability

(21-bit address full output (2 Mbyte address space) capability : MB91F353A/353A/352A/351A)

• 8,16-bit data output

• Built-in prefetch buffer

• Unused data and address pins can be used as general I/O ports.

• Able to output chip-select for 4 completely independent areas that can be configured in units of 64 Kbytes

• Support for various memory interfaces :

SRAM, ROM/Flash

page mode Flash ROM, page mode ROM interface

• Basic bus cycle : 2 cycles

• Programmable automatic wait cycle generator capable of inserting wait cycles for each area

• RDY input for external wait cycles

• DMA support of fly-by transfer capable of wait control for independent I/O

(The MB91F353A/353A/352A/351A does not support fly-by transfer.)

4. DMAC (DMA Controller)

• Capable of simultaneous operation of up to 5 channels (external → external : 3 channels)

• 3 transfer sources (external pin, internal peripheral or software) :

Activation sources are software-selectable (transfer can be activated by UART0/1/2).

• Addressing using 32-bit full addressing mode (increment, decrement, fixed)

• Transfer modes (demand transfer, burst transfer, step transfer, block transfer)

• Fly-by transfer support (between external I/O and memory)

• Selectable transfer data size : 8, 16, or 32-bit

• Multi-byte transfer capability (selected by software)

• DMAC descriptor in IO areas (200H to 240H, 1000H to 1024H)

(The MB91F353A/353A/352A/351A does not have an external interface.)

External pin transfer is not supported. Demand transfer and fly-by transfer cannot be used.

5. Bit search module (for REALOS)

• Search a single word starting from the MSB for the position of the first bit changed from 1 to 0.
