back to main page

1. Introduction

The ST67W611M1 module can be configured in low power as can be seen in the datasheet. Deep-sleep mode is available.

A hardware wake-up signal needs to be sent to leave the Deep-sleep mode.

2. Wake-up pins hardware implementation

Besides its role in the SPI protocol (see the SPI related page), SPI_CS (24) pin is used to convey the wake-up signal to the module. This pin is 3.3 V and must be connected to the Host which will send the wake-up command. Refer to the software documentation for more details.
