G
Low-power consumption (standby) mode
• Sleep mode (stops CPU clock)
• Timebase timer mode (operates only oscillation clock and sub clock, timebase timer and watch timer)
• Watch mode (operates only sub clock and watch timer)
• Stop mode (stops oscillation clock and sub clock)
• CPU Intermittent operation mode
G
Process
• CMOS Technology
G
I/O port
• General-purpose I/O ports (CMOS output): 34 ports (for MB90F897) (included 4 output ports for high
current) note: 36 ports (for MB90F897S) on condition of unusing sub-clock.
G
Timers
• Timebase timer, watch timer, watchdog timer: 1 channel
• 8/16-bit PPG timer: 8 bits x 4 channels or 16 bits x 2 channels
• 16-bit reload timer: 2 channels
• 16-bit I/O timer
- 16-bit free-run timer: 1 channel
- 16-bit input capture (ICU): 4 channels
By detecting the edge of the pin input, the count value of the 16-bit free-run timer is latched to generate an
interrupt request.
G
CAN Controller: 1 channel
• Conforms to CAN Specification Ver.2.0A and Ver.2.0B.
• Built-in 8 message buffers
• Transfer rate: 10 Kbps to 1 Mbps (at 16-MHz machine clock frequency)
• CAN wake-up
G
UART0(SCI),UART1(SCI): 2 channel
• Full-duplex double buffer
• Clock asynchronous or clock synchronous serial transfer
G
DTP/external interrupt: 4 channels, CAN wake-up: 1channel
• External input to start EI
G
Delayed interrupt generation module
• Generates interrupt request for task switching
G
8-/10-bit A/D converter: 8 channels
• The resolution can be switched between 8 and 10 bits.
• Start by external trigger input
• Conversion time: 6.125µs (including sampling time at 16-MHz machine clock frequency)
G
Program patch function
• Detects address match for two address pointers
