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.jpg 18 :align: center 19 :alt: AcSIP S76S system on a chip, containing STMicro STM32L073RZ and Semtech SX1276 20 21 AcSIP S76S 22 23================ 24Device Resources 25================ 26 27The embedded `STMicro STM32L073RZ`_ has some GPIOs and SPI2 internally committed to the LoRaWAN 28transceiver operation. See `internally committed table`_ for a list of resources committed to this function. 29 30As a result, some functions, ports and features of the `STMicro STM32L073RZ`_ are not available. 31See `unavailable table`_ for a list of resources not available due to a lack of pin-out. 32 33Available pinned-out resources are listed in `this table`_. The actual `S76S pinout table`_ is below. 34 35These tables are STM32L07x generic - some pinned-out resources may be unavailable due to limitations 36on the `STMicro STM32L073RZ`_ processor itself. Consult with the `STMicro STM32L073RZ`_ documentation. 37 38=========== 39Development 40=========== 41 42The Ronoth_ LoDev_ board is an open source development board, see its board description files. 43 44========= 45Debugging 46========= 47 48Programming and debugging uses the SWD port, as on any STM32 processor. An ST-LINK/V2 adapter 49may be used with the appropriate software (*st-utils* package on Linux). 50 51.. _S76S pinout table: 52 53================================== 54Pin Assignments and Available Pins 55================================== 56 57------------------- 58S76S Pin Assignment 59------------------- 60 61=== ================ === ================ 62Pin Function Pin Function 63=== ================ === ================ 641 NC 32 GND 652 GND 33 RF_ANT 663 GND 34 GND 674 PC1 35 GND 685 PC2 36 PA1\_RF\_FEM_CPS 696 PC3 37 GND 707 NC 38 NC 718 NC 39 GND 729 NC 40 NC 7310 NC 41 GND 7411 NC 42 NC 7512 nReset 43 VDD 7613 PA0 44 VDD 7714 GND 45 PA8\_USART1\_CK 7815 GND 46 PA10\_USART1\_RX 7916 PA2\_TxD\_A 47 PA9\_USART1\_TX 8017 PA3\_RxD\_A 48 PA11\_USART1\_CTS 8118 PA4\_SPI1\_NSS 49 PA12\_USART1\_RTS 8219 PA5\_SPI1\_SCK 50 PA13_SWDIO 8320 PA6\_SPI1\_MISO 51 PA14_SWCLK 8421 PA7\_SPI1\_MOSI 52 PC10 8522 PC4 53 PC11 8623 PC5 54 PC12 8724 PB0\_IO\_INT1 55 PD2 8825 PB1\_IO\_INT2 56 PB5 8926 PC6 57 PB6_SCL 9027 PC7 58 PB7_SDA 9128 PC8 59 BOOT0 9229 PC9 60 PB8\_IO\_LED_FCT 9330 RXTX/RFMOD 61 GND 9431 GND 62 GND 95=== ================ === ================ 96 97.. _this table: 98 99-------------------------------- 100Ports Connected to External Pins 101-------------------------------- 102 103======== ======== ============= ==== ========================================================================================================== ======================================= 104Pin name Pin Type I/O Structure Note Alternate functions Additional functions 105======== ======== ============= ==== ========================================================================================================== ======================================= 106BOOT0 I - - - 107NRST I/O - - - - 108PA0 I/O TC - TIM2_CH1, TSC_G1_IO1, USART2_CTS, TIM2_ETR, USART4_TX, COMP1_OUT COMP1_INM, ADC_IN0, RTC_TAMP2/WKUP1 109PA1 I/O FT - EVENTOUT, LCD_SEG0, TIM2_CH2, TSC_G1_IO2, USART2_RTS/USART2_DE, TIM21_ETR, USART4_RX COMP1_INP, ADC_IN1 110PA2 I/O FT - TIM21_CH1, LCD_SEG1, TIM2_CH3, TSC_G1_IO3, USART2_TX, LPUART1_TX, COMP2_OUT COMP2_INM, ADC_IN2 111PA3 I/O FT - TIM21_CH2, LCD_SEG2, TIM2_CH4, TSC_G1_IO4, USART2_RX, LPUART1_RX COMP2_INP, ADC_IN3 112PA4 I/O TC (1) SPI1_NSS, TSC_G2_IO1, USART2_CK, TIM22_ETR COMP1_INM, COMP2_INM, ADC_IN4, DAC_OUT1 113PA5 I/O TC - SPI1_SCK, TIM2_ETR, TSC_G2_IO2, TIM2_CH1 COMP1_INM, COMP2_INM, ADC_IN5, DAC_OUT2 114PA6 I/O FT - SPI1_MISO, LCD_SEG3, TIM3_CH1, TSC_G2_IO3, LPUART1_CTS, TIM22_CH1, EVENTOUT, COMP1_OUT ADC_IN6 115PA7 I/O FT - SPI1_MOSI, LCD_SEG4, TIM3_CH2, TSC_G2_IO4, TIM22_CH2, EVENTOUT, COMP2_OUT ADC_IN7 116PA8 I/O FTf - MCO, LCD_COM0, USB_CRS_SYNC, EVENTOUT, USART1_CK, I2C3_SCL - 117PA9 I/O FTf - MCO, LCD_COM1, TSC_G4_IO1, USART1_TX, I2C1_SCL, I2C3_SMBA - 118PA10 I/O FTf - LCD_COM2, TSC_G4_IO2, USART1_RX, I2C1_SDA - 119PA11 I/O FT (2) SPI1_MISO, EVENTOUT, TSC_G4_IO3, USART1_CTS, COMP1_OUT USB_DM 120PA12 I/O FT (2) SPI1_MOSI, EVENTOUT, TSC_G4_IO4, USART1_RTS/USART1_DE, COMP2_OUT USB_DP 121PA13 I/O FT - SWDIO, USB_NOE, LPUART1_RX - 122PA14 I/O FT - SWCLK, USART2_TX, LPUART1_TX - 123PB0 I/O FT - EVENTOUT, LCD_SEG5, TIM3_CH3, TSC_G3_IO2 LCD_VLCD3, ADC_IN8, VREF_OUT 124PB1 I/O FT - LCD_SEG6, TIM3_CH4, TSC_G3_IO3, LPUART1_RTS/LPUART1_DE ADC_IN9, VREF_OUT 125PB5 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 126PB6 I/O FTf - USART1_TX, I2C1_SCL, LPTIM1_ETR, TSC_G5_IO3 COMP2_INP 127PB7 I/O FTf - USART1_RX, I2C1_SDA, LPTIM1_IN2, TSC_G5_IO4, USART4_CTS COMP2_INP, PVD_IN 128PB8 I/O FTf - LCD_SEG16, TSC_SYNC, I2C1_SCL - 129PC1 I/O FTf - LPTIM1_OUT, LCD_SEG19, EVENTOUT, TSC_G7_IO2, LPUART1_TX, I2C3_SDA ADC_IN11 130PC2 I/O FTf - LPTIM1_IN2, LCD_SEG20, SPI2_MISO/I2S2_MCK, TSC_G7_IO3 ADC_IN12 131PC3 I/O FT - LPTIM1_ETR, LCD_SEG21, SPI2_MOSI/I2S2_SD, TSC_G7_IO4 ADC_IN13 132PC4 I/O FT - EVENTOUT, LCD_SEG22, LPUART1_TX ADC_IN14 133PC5 I/O FT - LCD_SEG23, LPUART1_RX, TSC_G3_IO1 ADC_IN15 134PC6 I/O FT - TIM22_CH1, LCD_SEG24, TIM3_CH1, TSC_G8_IO1 - 135PC7 I/O FT - TIM22_CH2, LCD_SEG25, TIM3_CH2, TSC_G8_IO2 - 136PC8 I/O FT - TIM22_ETR, LCD_SEG26, TIM3_CH3, TSC_G8_IO3 - 137PC9 I/O FTf - TIM21_ETR, LCD_SEG27, USB_NOE/TIM3_CH4, TSC_G8_IO4, I2C3_SDA - 138PC10 I/O FT - LPUART1_TX, LCD_COM4/LCD_SEG2 8/LCD_SEG48, USART4_TX - 139PC11 I/O FT - LPUART1_RX, LCD_COM5/LCD_SEG2 9/LCD_SEG49, USART4_RX - 140PC12 I/O FT - LCD_COM6/LCD_SEG3 0/LCD_SEG50, USART5_TX, USART4_CK - 141PD2 I/O FT - LPUART1_RTS/LPUART1_DE, LCD_COM7/LCD_SEG3 1/LCD_SEG51, TIM3_ETR, USART5_RX - 142======== ======== ============= ==== ========================================================================================================== ======================================= 143 144Notes: 145 1461.
