SE050

Plug & Trust Secure Element

• CPU registers keep their contents

• RAM keeps its contents

The SE050 enters into Power-down mode by receiving "End of APDU session request"

via the T=1 over I2C protocol. In Power-down mode, all internal clocks are frozen. The

IOs hold the logical states they had at the time Power-down mode was activated.

To exit from the Power-down mode an external interrupt edge must be triggered by a

falling edge on I2C_SDA2.

5.2 Deep Power-down mode

The SE050 provides a special power-saving mode offering maximum power saving. This

mode is activated by pulling enable PIN (ENA) to a logic zero level.

While in Deep Power-down mode the internal power and VOUT is switched off completely

and only the I2C pads stay supplied.

To leave the Deep Power-down mode pad ENA has to be pulled up to to a logic „1" level.

For usage of Deep Power-down mode the SE050 must be supplied via pin VIN and pin

VCC needs to be supplied by pin VOUT.

In case ISO7816 is enabled a reset signal on RST_N exits the Power-down mode. After wake-up from

Power-down mode via RST_N the device is in idle mode (see Table 12)
