1.. _acsip_s76s: 2 3AcSIP S76S 4########## 5 6======== 7Overview 8======== 9 10The `AcSIP S76S`_ is an SiP from AcSIP_ containing an `STMicro STM32L073RZ`_ MCU, 11a `Semtech SX1276`_ LoRaWAN transceiver, and a +20 dBm power amplifier. Refer to the 12`AcSIP S76S Product Information Brief`_ for details. Further information is available 13from the `AcSIP Product Data Download`_ site (may need login). The parts are `available through TechShip`_. 14 15Zephyr applications may use the **acsip_s76s** configuration to use this SiP. 16 17.. figure:: img/acsip_s76s.png 18 :width: 189px 19 :align: center 20 :height: 115px 21 :alt: AcSIP S76S system on a chip, containing STMicro STM32L073RZ and Semtech SX1276 22 23 AcSIP S76S 24 25================ 26Device Resources 27================ 28 29The embedded `STMicro STM32L073RZ`_ has some GPIOs and SPI2 internally committed to the LoRaWAN 30transceiver operation. See `internally committed table`_ for a list of resources committed to this function. 31 32As a result, some functions, ports and features of the `STMicro STM32L073RZ`_ are not available. 33See `unavailable table`_ for a list of resources not available due to a lack of pin-out. 34 35Available pinned-out resources are listed in `this table`_. The actual `S76S pinout table`_ is below. 36 37These tables are STM32L07x generic - some pinned-out resources may be unavailable due to limitations 38on the `STMicro STM32L073RZ`_ processor itself. Consult with the `STMicro STM32L073RZ`_ documentation. 39 40=========== 41Development 42=========== 43 44The Ronoth_ LoDev_ board is an open source development board, see its board description files. 45 46========= 47Debugging 48========= 49 50Programming and debugging uses the SWD port, as on any STM32 processor. An ST-LINK/V2 adapter 51may be used with the appropriate software (*st-utils* package on Linux). 52 53.. _S76S pinout table: 54 55================================== 56Pin Assignments and Available Pins 57================================== 58 59------------------- 60S76S Pin Assignment 61------------------- 62 63=== ================ === ================ 64Pin Function Pin Function 65=== ================ === ================ 661 NC 32 GND 672 GND 33 RF_ANT 683 GND 34 GND 694 PC1 35 GND 705 PC2 36 PA1\_RF\_FEM_CPS 716 PC3 37 GND 727 NC 38 NC 738 NC 39 GND 749 NC 40 NC 7510 NC 41 GND 7611 NC 42 NC 7712 nReset 43 VDD 7813 PA0 44 VDD 7914 GND 45 PA8\_USART1\_CK 8015 GND 46 PA10\_USART1\_RX 8116 PA2\_TxD\_A 47 PA9\_USART1\_TX 8217 PA3\_RxD\_A 48 PA11\_USART1\_CTS 8318 PA4\_SPI1\_NSS 49 PA12\_USART1\_RTS 8419 PA5\_SPI1\_SCK 50 PA13_SWDIO 8520 PA6\_SPI1\_MISO 51 PA14_SWCLK 8621 PA7\_SPI1\_MOSI 52 PC10 8722 PC4 53 PC11 8823 PC5 54 PC12 8924 PB0\_IO\_INT1 55 PD2 9025 PB1\_IO\_INT2 56 PB5 9126 PC6 57 PB6_SCL 9227 PC7 58 PB7_SDA 9328 PC8 59 BOOT0 9429 PC9 60 PB8\_IO\_LED_FCT 9530 RXTX/RFMOD 61 GND 9631 GND 62 GND 97=== ================ === ================ 98 99.. _this table: 100 101-------------------------------- 102Ports Connected to External Pins 103-------------------------------- 104 105======== ======== ============= ==== ========================================================================================================== ======================================= 106Pin name Pin Type I/O Structure Note Alternate functions Additional functions 107======== ======== ============= ==== ========================================================================================================== ======================================= 108BOOT0 I - - - 109NRST I/O - - - - 110PA0 I/O TC - TIM2_CH1, TSC_G1_IO1, USART2_CTS, TIM2_ETR, USART4_TX, COMP1_OUT COMP1_INM, ADC_IN0, RTC_TAMP2/WKUP1 111PA1 I/O FT - EVENTOUT, LCD_SEG0, TIM2_CH2, TSC_G1_IO2, USART2_RTS/USART2_DE, TIM21_ETR, USART4_RX COMP1_INP, ADC_IN1 112PA2 I/O FT - TIM21_CH1, LCD_SEG1, TIM2_CH3, TSC_G1_IO3, USART2_TX, LPUART1_TX, COMP2_OUT COMP2_INM, ADC_IN2 113PA3 I/O FT - TIM21_CH2, LCD_SEG2, TIM2_CH4, TSC_G1_IO4, USART2_RX, LPUART1_RX COMP2_INP, ADC_IN3 114PA4 I/O TC (1) SPI1_NSS, TSC_G2_IO1, USART2_CK, TIM22_ETR COMP1_INM, COMP2_INM, ADC_IN4, DAC_OUT1 115PA5 I/O TC - SPI1_SCK, TIM2_ETR, TSC_G2_IO2, TIM2_CH1 COMP1_INM, COMP2_INM, ADC_IN5, DAC_OUT2 116PA6 I/O FT - SPI1_MISO, LCD_SEG3, TIM3_CH1, TSC_G2_IO3, LPUART1_CTS, TIM22_CH1, EVENTOUT, COMP1_OUT ADC_IN6 117PA7 I/O FT - SPI1_MOSI, LCD_SEG4, TIM3_CH2, TSC_G2_IO4, TIM22_CH2, EVENTOUT, COMP2_OUT ADC_IN7 118PA8 I/O FTf - MCO, LCD_COM0, USB_CRS_SYNC, EVENTOUT, USART1_CK, I2C3_SCL - 119PA9 I/O FTf - MCO, LCD_COM1, TSC_G4_IO1, USART1_TX, I2C1_SCL, I2C3_SMBA - 120PA10 I/O FTf - LCD_COM2, TSC_G4_IO2, USART1_RX, I2C1_SDA - 121PA11 I/O FT (2) SPI1_MISO, EVENTOUT, TSC_G4_IO3, USART1_CTS, COMP1_OUT USB_DM 122PA12 I/O FT (2) SPI1_MOSI, EVENTOUT, TSC_G4_IO4, USART1_RTS/USART1_DE, COMP2_OUT USB_DP 123PA13 I/O FT - SWDIO, USB_NOE, LPUART1_RX - 124PA14 I/O FT - SWCLK, USART2_TX, LPUART1_TX - 125PB0 I/O FT - EVENTOUT, LCD_SEG5, TIM3_CH3, TSC_G3_IO2 LCD_VLCD3, ADC_IN8, VREF_OUT 126PB1 I/O FT - LCD_SEG6, TIM3_CH4, TSC_G3_IO3, LPUART1_RTS/LPUART1_DE ADC_IN9, VREF_OUT 127PB5 I/O FT - SPI1_MOSI, LCD_SEG9, LPTIM1_IN1, I2C1_SMBA, TIM3_CH2/TIM22_CH2, USART1_CK, USART5_CK, USART5_RTS/USART5_DE COMP2_INP 128PB6 I/O FTf - USART1_TX, I2C1_SCL, LPTIM1_ETR, TSC_G5_IO3 COMP2_INP 129PB7 I/O FTf - USART1_RX, I2C1_SDA, LPTIM1_IN2, TSC_G5_IO4, USART4_CTS COMP2_INP, PVD_IN 130PB8 I/O FTf - LCD_SEG16, TSC_SYNC, I2C1_SCL - 131PC1 I/O FTf - LPTIM1_OUT, LCD_SEG19, EVENTOUT, TSC_G7_IO2, LPUART1_TX, I2C3_SDA ADC_IN11 132PC2 I/O FTf - LPTIM1_IN2, LCD_SEG20, SPI2_MISO/I2S2_MCK, TSC_G7_IO3 ADC_IN12 133PC3 I/O FT - LPTIM1_ETR, LCD_SEG21, SPI2_MOSI/I2S2_SD, TSC_G7_IO4 ADC_IN13 134PC4 I/O FT - EVENTOUT, LCD_SEG22, LPUART1_TX ADC_IN14 135PC5 I/O FT - LCD_SEG23, LPUART1_RX, TSC_G3_IO1 ADC_IN15 136PC6 I/O FT - TIM22_CH1, LCD_SEG24, TIM3_CH1, TSC_G8_IO1 - 137PC7 I/O FT - TIM22_CH2, LCD_SEG25, TIM3_CH2, TSC_G8_IO2 - 138PC8 I/O FT - TIM22_ETR, LCD_SEG26, TIM3_CH3, TSC_G8_IO3 - 139PC9 I/O FTf - TIM21_ETR, LCD_SEG27, USB_NOE/TIM3_CH4, TSC_G8_IO4, I2C3_SDA - 140PC10 I/O FT - LPUART1_TX, LCD_COM4/LCD_SEG2 8/LCD_SEG48, USART4_TX - 141PC11 I/O FT - LPUART1_RX, LCD_COM5/LCD_SEG2 9/LCD_SEG49, USART4_RX - 142PC12 I/O FT - LCD_COM6/LCD_SEG3 0/LCD_SEG50, USART5_TX, USART4_CK - 143PD2 I/O FT - LPUART1_RTS/LPUART1_DE, LCD_COM7/LCD_SEG3 1/LCD_SEG51, TIM3_ETR, USART5_RX - 144======== ======== ============= ==== ========================================================================================================== ======================================= 145 146Notes: 147 1481. PA4 offers a reduced touch sensing sensitivity. It is thus recommended to use it as sampling capacitor I/O. 1492. These pins are powered by VDD_USB.
