Maximum operating frequency
CPU : 60 MHz
Resources : 40 MHz
External bus : 40 MHz
Note: The PLL clock specification of MB91645A series
In MB91645A series, PLL clock specification has been modified from MB91645 series. The setting of dividing
by 1 of PLL macro oscillation clock divide configuration value is prohibited.
Therefore, please use the device with setting as dividing by 2 to 4 by ODS0 or ODS1 bit in the PLL config-
uration register (PLLCR) . For more details, refer to “4.4.4 PLL Configuration Register (PLLCR) ” in the
“Hardware Manual”.
External bus interface
Operating frequency : Max 40 MHz
24 address lines, 8- or 16-bit data I/O (separate busses or multiplexed bus)
Chip select output available for 4 independent programmable areas
Programmable automatic wait cycle insertion for each area
DMA controller (DMAC)
8 channels
Address space : 32 bits (4 Gbytes)
Transfer modes : Block transfer/burst transfer/demand transfer
Address update : Increment/decrement/fixed (increment/decrement step size of 1, 2, or 4)
Transfer data length : Selectable from 8-bit, 16-bit, 32-bit
Block size : 1 to 16
Number of transfers : 1 to 65535
Transfer requests
- Requests from software
- Interrupt requests from peripheral resources (interrupt requests are shared, including external interrupts)
- Requests from external pins
Reload functions : Reload can be specified on all channels
Priority order : Fixed (ch.0 > ch.1 > ch.2 > ch.3 > ...) or round-robin
Interrupt requests : Interrupts can be generated for transfer complete, transfer error, and transfer interrupted.
