Low voltage 8-bit microcontroller with

6-kbyte embedded RAM

SZF2002

2. The operating supply current is measured with all output pins disconnected; CLK driven with tr =tf =10ns;

VIL =VSS;VIH =VDD; EA = RST = Port 0 = VDD.

3. The Idle mode supply current is measured with all output pins disconnected; CLK driven with tr =tf = 10 ns; VIL =VSS;

VIH =VDD; EA = Port 0 = VDD.

4. The power-down current is measured with all output pins disconnected; CLK connected to VSS; EA = Port 0 = VDD;

RST=VSS.

5. The input threshold voltage of P1.6/SCL and P1.7/SDA meet the I2C-bus specification. Therefore, an input voltage

below 0.3VDD will be recognized as a logic 0 and an input voltage above 0.7VDD will be recognized as a logic 1.

26 ADC CHARACTERISTICS

Notes

1. All ADC inputs require an external divide-by-2 voltage divider.

2. Gain error: the maximum difference between actual and ideal slope.

3. Zero-offset error: the difference between the actual and ideal input voltage corresponding to the first actual code

transition.

4. Differential non-linearity: the difference between the actual and ideal code widths.

5. Integral non-linearity: maximum deviation from straight line.

6. Channel-to-channel matching: the difference between corresponding code transitions of actual characteristics taken

from different channels under the same temperature, voltage and frequency conditions. Not tested, but verified on

sampling basis.
