TIMING DIAGRAM: READ DATA TRANSFER Figure 5

TIMING DIAGRAM: WRITE DATA TRANSFER Figure 6

NOTES:

1. All voltages are referenced to ground.

2. Logic one voltages are specified at a source current of 1 mA at VCC=5V and 0.4 mA at VCC=2.0V,

VOH=VCC for capacitive loads.

3. Logic zero voltages are specified at a sink current of 4 mA at VCC=5V and 1.5 mA at VCC=2.0V,

VOL=GND for capacitive loads.

4. ICC1T and ICC2T are specified with I/O open, RST set to a logic “0”, and clock halt flag=0 (oscillator

enabled).

5. ICC1A and ICC2A are specified with the I/O pin open, RST high, SCLK=2 MHz at VCC=5V;

SCLK=500 kHz, VCC=2.0V and clock halt flag=0 (oscillator enabled).

6. RST , SCLK, and I/O all have 40 kΩ pull–down resistors to ground.

7. Measured at VIH=2.0V or VIL=0.8V and 10 ns maximum rise and fall time.

8. Measured at VOH=2.4V or VOL=0.4V.

9. Load capacitance = 50 pF.

10. ICC1S and ICC2S are specified with RST , I/O, and SCLK open. The clock halt flag must be set to logic

one (oscillator disabled).

11. VCC=VCC2, when VCC2>VCC1 +0.2V; VCC=VCC1, when VCC1>VCC2.

12. VCC2=0V.

13. VCC1=0V.

14. Typical values are at 25°C.
