III-42 Slave Controller – ET1100 Hardware Description
3.10.2 Logic Core Power Supply
Table 46 shows the pins for core power supply. Core supply voltage is 2.5V. The core power is either
generated by the internal LDO, which is sourced by the I/O power supply, or externally. In both cases,
voltage stabilization capacitors have to be connected to V
