Notes to the DC characteristics
1. Conditions for:
a) The digital operating current measurement: all output pins disconnected; XTAL1 is driven with t_r = t_f = 10 ns;
V_IL = V_SS + 0.5 V; V_IH = V_DD − 0.5 V; EA = RST = Port 0 = P1.6 = P1.7 = EW = V_DD;
STADC = V_SS; CRX0 = 2.7 V; CRX1 = 2.3 V.
b) The analog operating current measurement: Port 5 = AV_DD; CAN: register 6: = 00H;
load current reference voltage source 100 µA.
2. Conditions for:
a) The digital Idle mode supply current measurement: all output pins disconnected;
XTAL1 is driven with t_r = t_f = 10 ns; V_IL = V_SS + 0.5 V; V_IH = V_DD − 0.5 V; Port 0 = P1.6 = P1.7 = EW = V_DD;
EA = RST = STADC = V_SS; CRX0 = 2.7 V; CRX1 = 2.3 V.
b) The analog Idle mode current measurement: Port 5 = AV_DD; CAN: register 6: = 00H;
load current reference voltage source 100 µA.
3. Conditions for:
a) The digital Idle and Sleep mode supply current measurement: all output pins disconnected;
XTAL1 is driven with t_r = t_f = 10 ns; V_IL = V_SS + 0.5 V; V_IH = V_DD − 0.5 V;
Port 0 = P1.6 = P1.7 = EW = CRX0 = V_DD; EA = RST = STADC = CRX1 = V_SS;
CAN: register 6: = 00H, register 7: = 12H, register 8: = 02H, register 0: = 20H, wait 15t_CY,
register 1: = 10H, wait for bit Sleep = 1.
b) The analog Idle and Sleep mode current measurement: Port 5 = AV_DD;
load current reference voltage source 100 µA.
4. Window devices have to be covered. Conditions for:
a) The digital Power-down mode supply current measurement: all output pins and Port 5 disconnected;
Port 0 = P1.6 = P1.7 = EW = CRX0 = V_DD;
EA = RST = STADC = CRX1 = XTAL1 = AV_REF+ = AV_REF− = CV_SS = V_SS;
AV_DD = V_DD, but current into AVDD pin is not comprised in digital Power-down current.
b) The analog Power-down mode supply current measurement: Port 5 = AV_DD.
5. Capacitive loads on Port 0 and Port 2 may degrade the LOW level output voltage of ALE, Port 1 and Port 3.
During a HIGH-to-LOW transition on the Port 0 and Port 2 pins and a capacitive load > 100 pF, the ALE LOW level
may exceed 0.8 V. In the case that it is necessary to connect ALE to a Schmitt trigger input respectively use an
address latch with a Schmitt trigger STROBE input.
