5.1. SanDisk iNAND Power Domains
SanDisk iNAND has three power domains assigned to VDDH, VDDF, and CREG as shown in Table 14.
5.2. Capacitor Connection Guidelines
5.2.1. CREG Connections
The CREG (K2) ball must only be connected to an external capacitor that is connected to VSS. This signal may not
be left floating. The capacitor’s specifications and its placement instructions are detailed below.
The capacitor is part of an internal voltage regulator that provides power to the controller.
Caution: Failure to follow the guidelines below or connecting the CREG ball to any external signal or power
supply may cause the device to malfunction.
The trace requirements from the CREG (K2) ball to the capacitor are as follows:
The capacitor requirements are as follows:
Currently both power domains can be connected to the same 3.3V (nom) power supply. However, in order to
provide maximum flexibility and support low power operation in future iNAND devices, the PCB should be
designed as follows:
