Clock timer
8/16-bit PPG timer
8/16 -bit up/down
counter/timers
15-bit timer
Interrupt interval : 0.438, 0.5, or 2.0 µs for sub-clock frequency = 32.768 kHz
Number of channels : 1 (Can be used in 2 × 8-bit channel mode)
Can generate a pulse waveform output with specified period and 0 to 100% duty ratio.
Number of channels : 1 (Can be used in 2 × 8-bit channel mode)
External event inputs : 6 channels
Reload/compare function : 8-bit × 2 channels
Clock monitor
Clock output frequency : Machine clock/21 to machine clock/28
Delayed interrupt
generation module
Interrupt generation module for task switching. (Used by REALOS.)
DTP/External
interrupts
Input channels : 8
Generates interrupts to the CPU on rising edges, falling edges with input “H” level, or “L”
level.
Can be used for external event interrupts and to activate EI2OS.
Wakeup interrupts
Input channels : 8
Triggered by “L” level.
8/10-bit A/D converter
(successive
approximation type)
Number of channels : 8
Resolution : 8-bit or 10-bit selectable
Conversion can be performed sequentially for multiple consecutive channels.
• Single-shot conversion mode : Converts specified channel once only.
• Continuous conversion mode : Repeatedly converts specified channel.
• Intermittent conversion mode : Converts specified channel then halts temporarily.
8-bit D/A converter
(R-2R type)
Number of channels : 2
Resolution : 8-bit
UART (SCI)
Number of channels : 1
Clock synchronous transfer : 62.5 Kbps to 1 Mbps
Clock asynchronous transfer : 1202 bps to 31250 bps
Supports bi-directional and master-slave communications.
Extended I/O serial
interface
Number of channels : 2
Clock synchronous transfer : 31.25 Kbps to 1 Mbps (Using internal shift clock)
Transmission format : Selectable LSB-first or MSB-first
LCD controller/driver
Number of common outputs : 4
Number of segment outputs : 32
Number of power supply pins for LCD drive : 4
LCD display memory : 16 bytes
Divider resistor for LCD drive : Internal
*1 : As for the necessity of a DIP switch setting (S2) when using the emulation pod (MB2145-507) .
Refer to the hardware manual for the emulation pod (MB2145-507) fomr details.
*2 : Take note of the maximum operating frequency and A/D converter precision restrictions when operating at 3.0 V
to 3.6 V. See the “Electrical Characteristics” section for details.
