| AcSIP S76S |
| ########## |
| |
| ======== |
| Overview |
| ======== |
| |
| The `AcSIP S76S`_ is an SiP from AcSIP_ containing an `STMicro STM32L073RZ`_ MCU, |
| a `Semtech SX1276`_ LoRaWAN transceiver, and a +20 dBm power amplifier. Refer to the |
| `AcSIP S76S Product Information Brief`_ for details. Further information is available |
| from the `AcSIP Product Data Download`_ site (may need login). The parts are `available through TechShip`_. |
| |
| Zephyr applications may use the **acsip_s76s** configuration to use this SiP. |

| ================ |
| Device Resources |
| ================ |
| |
| The embedded `STMicro STM32L073RZ`_ has some GPIOs and SPI2 internally committed to the LoRaWAN |
| transceiver operation. See `internally committed table`_ for a list of resources committed to this function. |
| |
| As a result, some functions, ports and features of the `STMicro STM32L073RZ`_ are not available. |
| See `unavailable table`_ for a list of resources not available due to a lack of pin-out. |
| |
| Available pinned-out resources are listed in `this table`_. The actual `S76S pinout table`_ is below. |
| |
| These tables are STM32L07x generic - some pinned-out resources may be unavailable due to limitations |
| on the `STMicro STM32L073RZ`_ processor itself. Consult with the `STMicro STM32L073RZ`_ documentation. |
| |
| =========== |
| Development |
| =========== |
| |
| The Ronoth_ LoDev_ board is an open source development board, see its board description files. |
| |
| ========= |
| Debugging |
| ========= |
| |
| Programming and debugging uses the SWD port, as on any STM32 processor. An ST-LINK/V2 adapter |
| may be used with the appropriate software (*st-utils* package on Linux). |

| Notes: |
| |
| 1. PA4 offers a reduced touch sensing sensitivity. It is thus recommended to use it as sampling capacitor I/O. |
| 2. These pins are powered by VDD_USB. For all characteristics that refer to VDD, VDD_USB must be used instead. |
