DS2404S-001 技术参数

DS2404

NOTES:

1. All voltages are referenced to ground.

2. V_IH= 2.0V or V_IL= 0.8V with 10 ns maximum rise and fall time.

3. V_DQH= 2.4V and V_DQL= 0.4V, respectively.

4. Load capacitance = 50 pF.

5. Measured with outputs open.

6. When battery is applied to V_BATOinput, V_CCand V_BATBmust be 0V.

7. V_BATB, or V_BATO= 3.0V; all inputs inactive state.

8. Capacitance on the I/O pin could be 800 pF when power is first applied. If a 5kW resistor is used to

pullup the I/O line to V_PUP, 5 ms after power has been applied, the parasite capacitance will not affect

normal communications.

9. For auto-mode operation of the interval timer, the high level on the I/O pin must be greater than or

equal to 70% of V_CCor V_BATO

10. Read and write scratchpad (all 32 bytes) at 3.0V.

11. All other inputs at CMOS levels.

12. V_PUP= external pullup voltage.

13. Input load is to ground.

14. An additional reset or communication sequence cannot begin until the reset high time has expired.

15. Read data setup time refers to the time the host must pull the I/O line low to read a bit. Data is

guaranteed to be valid within 1 ms of this falling edge.

16. Under certain low voltage conditions V_IL1MAXmay have to be reduced to as much as 0.5V to always

guarantee a presence pulse.

17. Applies to 1Hz and IRQ pins only.

18. Applies to DQ pin only.

19. Applies to DQ, 1Hz and IRQ pins only.

20. The reset low time (t_RSTL) should be restricted to a maximum of 960 ms, to allow interrupt signaling,

otherwise, it could mask or conceal interrupt pulses.

21. When the battery is attached, the oscillator powers up in the off state.
