Features
• 10-channel DMA
• Supports transfer between internal peripheral I/Os and between internal peripheral I/O
and internal RAM.
• Capable of advanced DMA transfer when operating in combination with internal
peripheral I/O
• Capable of cascaded connection between DMA channels (DMA transfer in a channel
is started by completion of transfer in another)
• 64-channel multifunction timer
• Contains output-related timer × 35 channels, input/output-related timer × 10 channels,
16-bit input-related timer × 11 channels, and 32-bit input-related timer × 8 channels.
• Capable of flexible timer configuration by mutual connection between each channel.
• 16-channel, 10-bit resolution A-D converter × 2 units
• Incorporates comparator mode
• Can generate interrupt or start DMA transfer upon completion of A-D conversion.
• Can read out conversion results in 8 or 10 bits.
• 6-channel serial I/O
• Can be set for clock-synchronized serial I/O or UART.
• Capable of high-speed data transfer at 2 Mbits per second when clock synchronized or
156 Kbits per second during UART.
from an external source.
• Has its exclusive clock-synchronized serial port.
• Accepts and manages interrupt requests from internal peripheral I/O.
• Resolves interrupt priority in 8 levels including interrupt-disabled state.
• Controls wait state for access to extended external areas.
• Can insert 1 to 4 wait cycles by setting in software and extend wait period by external
WAIT signal.
• Multiply-by-4 clock generator circuit
• Maximum 40 MHz of CPU clock (CPU, internal ROM, internal RAM access)
• Maximum 20 MHz of internal peripheral clock (peripheral module access)
• Maximum external input clock frequency=10 MHz
• Sixteen message slots
• Capable of boundary scan
