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 k 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.
