Warning!
Do not apply any other voltages to the PWR_EN pin than 3.3 V or GND, as this may damage the Mer-
cury ZX1 SoC module. PWR_EN pin can be left unconnected.
Do not power the VCC_IO pins (for example by connecting VCC_3V3 to VCC_IO directly) when PWR_EN
is driven low to disable the module. In this case, VCC_IO needs to be switched off in the manner
indicated in Figure 10.
2.11.3 Voltage Supply Inputs
Table 15 describes the power supply inputs on the Mercury ZX1 SoC module. The VCC voltages used as
supplies for the I/O banks are described in Section 2.9.6.
Pin Name Module Connector Pins Voltage Description
VCC_MOD A-1, 2, 3, 4, 5, 6, 7, 8, 9, 11 5 - 15 V ±5% Supply for the 1.0 V and 3.3 V voltage regu-
lators. All other supplies are generated from
the 3.3 V supply. The input current is rated at
3 A (0.3 A per connector pin).
VCC_BAT A-168 2.0 - 3.6 V Battery for the RTC and SoC encryption key
storage

2.11.4 Voltage Supply Outputs
Table 16 presents the supply voltages generated on the Mercury ZX1 SoC module, that are available on the
module connector.

Warning!
Do not connect any power supply to the voltage supply outputs nor short circuit them to GND, as this
may damage the Mercury ZX1 SoC module.
