DC Characteristics (Supply Current: C1M-A1)

Conditions: SYSVCC = VCC = 4.5 V to 5.5 V, VDD = 1.15 V to 1.35 V

A0VCC, A1VCC, A2VCC = 4.5 V to 5.5 V, A0VREFH = 4.5 V to A0VCC, A1VREFH = 4.5 V to A1VCC,

A2VREFH = 4.5 V to A2VCC, RVCC = 4.5 V to 5.5 V

VSS = A0VSS = A1VSS = A2VSS = RVSS = 0 V

Tj = –40ºC to 150ºC

Note 1.

Large fluctuations in current occur during erasure. The average current is 15 mA.

CAUTIONS

When the A/D converter is not used or it is in the standby state, do not open the A0VCC pin, A1VCC pin, A2VCC

pin, A0VREFH pin, A1VREFH pin, A2VREFH pin, A0VSS pin, A1VSS pin, and A2VSS pin.

Supply current values are those measured when VIHmin = VCC – 0.5 V and VIL = 0.5 V with no load applied to all

output pins.
