RA2A1 Datasheet

2. Electrical Characteristics

Note 1.

Use AVCC0, AVCC1, and VCC under the following conditions:

AVCC0, AVCC1, and VCC can be set individually within the operating range when VCC ≥ 2.2 V and AVCC0 = AVCC1 ≥ 2.2 V.

AVCC0 = AVCC1 = VCC when VCC < 2.2 V or AVCC0 = AVCC1 < 2.2 V.

Note 2.

When powering on the VCC and AVCC0 and AVCC1 pins, power them on at the same time or the VCC pin first and then the

AVCC0 and AVCC1 pins.

Note 3.

The condition when using external input for the reference voltage of SDADC24.

DC Characteristics

2.2.1

Tj/Ta Definition

Note:

Make sure that Tj = Ta + θja × total power consumption (W), where total power consumption = (VCC - VOH) × ΣIOH + VOL × ΣIOL

+ ICCmax × VCC.

Note 1.

The upper limit of operating temperature is 85°C or 105°C, depending on the product. For details, see section 1.3, Part

Numbering. If the part number shows the operation temperature at 85°C, then the maximum value of Tj is 105°C, otherwise it is

125°C.
