General-purpose I/O Ports (GPIO)
• Maximum 71 I/O ports and six input ports are available (144-pin package).
• Can generate maximum 16 input interrupts from 64 I/O ports.
• Supports DMA transfer.
*
The GPIO ports are shared with other peripheral function pins (USI, PWM etc.). Therefore, the number of
GPIO ports depends on the peripheral functions used.
Operating Voltage
• HV
DD
(I/O power voltage)
2.7 V to 3.6 V (3.3 V typ.)
or 3.0 V to 3.6 V (3.3 V typ.) when the USB module is used.
• AV
DD
(analog power voltage)
2.7 V to 3.6 V (3.3 V typ.) or 3.0 V to 3.6 V (3.3 V typ.)
• LV
DD
(core/internal logic power voltage)
1.65 V to 1.95 V (1.8 V typ.)
or 1.7 V to 1.9 V (1.8 V typ.) when a ceramic resonator is used.
• PLLV
DD
(PLL power voltage)
1.65 V to 1.95 V (1.8 V typ.)
or 1.7 V to 1.9 V (1.8 V typ.) when a ceramic resonator is used.
• RTCV
DD
(RTC/BBRAM power voltage)
1.65 V to 1.95 V (1.8 V typ.)
or 1.7 V to 1.9 V (1.8 V typ.) when a ceramic resonator is used.

The S1C33L26 does not support 5 V tolerant I/O.
Operating Temperatures
• -40 to 85°C
• 0 to 70°C when the USB module and a ceramic resonator are used.
Current Consumption
(No I/O current is included.)
• During SLEEP: 2.9 µA typ. when RTC is running.
1.6 µA typ. when RTC is not used.
• During HALT:
4.2 mA typ. when 48 MHz OSC3 clock is used as the system and CPU clocks,
all peripheral clocks = Off.
• During execution: 22 mA typ. when 48 MHz OSC3 clock is used as the system and CPU clocks,
CPU is running, all peripheral clocks = Off.
40 mA typ. when 48 MHz OSC3 clock is used as the system and CPU clocks,
CPU is running, GE is enabled and idles.
*
Current consumption can be reduced by controlling the clocks through the clock management unit (CMU).
