RA4W1 Datasheet

2. Electrical Characteristics

Note 1.

The reference power supply current is included in the power supply current value for D/A conversion.

Note 2.

Current consumed only by the USBFS.

Note 3.

Includes the current supplied from the pull-up resistor of the USB_DP pin to the pull-down resistor of the host device, in addition

to the current consumed by the MCU during the suspended state.

Note 4.

When VCC = VCC_USB = 3.3 V.

Note 5.

Current flowing only to the LCD controller. Not including the current that flows through the LCD panel.

Note 6.

When the MCU is in Software Standby mode or the MSTPCRD.MSTPD16 (ADC140 Module Stop bit) is in the module-stop

state.
