NOTES:
1. Power Down does not affect the operation of the ZPLD.The ZPLD operation in this mode is based
only on the ZPLD_Turbo Bit.
2. In Sleep Mode any input to the ZPLD will have a propagation delay of tLVDV2.
3. PLD recovery time to normal operation after existing Sleep Mode. An input to the ZPLD during the
transition will have a propagation delay of tLVDV3.
4. Typical current consumption assuming CLKIN is disabled and the ZPLD Turbo bit is off.
5. Typical current consumption assuming CLKIN is disabled.
Sleep Mode
The Sleep Mode is activated if the Sleep mode bit, the APD bit and the ALE Polarity bit in
the PMMRs are set, and the APD Counter has overflowed after 15 CLKIN clocks
(see Figure 28). In Sleep Mode the ZPSD6XX(V) consumes less power than the Power
Down Mode, with typical I
CC
reduced to 10μA.
In this mode, the ZPLD still monitors the inputs and responds to them. As soon as the ALE
starts pulsing or the CSI input switches from high to low, the ZPSD6XX(V) exits the Sleep
Mode. The ZPSD6XX(V) access time from Sleep Mode is specified by tLVDV1. The ZPLD
response time to an input transition is specified by tLVDV2.
