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 SA1 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.

Voltage Supply Inputs

Table 12 describes the power supply inputs on the Mercury SA1 SoC module. The VCC voltages used as
supplies for the I/O banks are described in Section 2.9.5.
Pin Name Module Connector Pins
VCC_MOD A-1, 2, 3, 4, 5, 6, 7, 8, 9, 11
VCC_BAT A-168

Voltage Supply Outputs

Table 13 presents the supply voltages generated on the Mercury SA1 SoC module, that are available on the
module connector.
D-0000-402-002
Remarks
Floating/3.3 V: Module power enabled
Driven low: Module power disabled
0 V: Module supply not ok
3.3 V: Module supply ok
Voltage Description
5 - 15 V 5% Supply for the 1.1 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).
