A 3.3 Strapping Pins IN Note: The content below is excerpted from Section Strapping Pins in ESP32-S3 Series Datasheet. For the strapping pin mapping between the chip and modules, please refer to Chapter 5 Module Schematics. ESP32-S3 has four strapping pins: IM · GPIO0 · GPIO45 L · GPIO46 · GPIO3 E Software can read the values of corresponding bits from register "GPIO_STRAPPING". During the chip's system reset (power-on-reset, RTC watchdog reset, brownout reset, analog super watchdog R reset, and crystal clock glitch detection reset), the latches of the strapping pins sample the voltage level as strapping bits of "0" or "1", and hold these bits until the chip is powered down or shut down. PGPIO0, GPIO45 and GPIO46 are connected to the chip's internal weak pull-up/pull-down during the chip reset. Consequently, if they are unconnected or the connected external circuit is high-impedance, the internal weak pull-up/pull-down will determine the default input level of these strapping pins. GPIO3 is floating by default. Its strapping value can be configured to determine the source of the JTAG signal inside the CPU, as shown in Table 4. In this case, the strapping value is controlled by the external circuit that cannot be in a high impedance state. Table 3 shows more configuration combinations of EFUSE_DIS_USB_JTAG, EFUSE_DIS_PAD_JTAG, and EFUSE_STRAP_JTAG_SEL that determine the JTAG signal source.

After reset, the strapping pins work as normal-function pins. Y Refer to Table 4 for a detailed configuration of the strapping pins. Table 4: Strapping Pins R Pin GPIO45 A Pin GPIO0 IN GPIO46 Pin GPIO46 IM Pin L GPIO3 VDD_SPI Voltage 1 Default 3.3 V 1.8 V Pull-down 0 1 Booting Mode 2 Default SPI Boot Download Boot Pull-up 1 0 Pull-down Don't care 0 Enabling/Disabling ROM Messages Print During Booting 3 4 Default Enabled Disabled Pull-down See the fourth note See the fourth note JTAG Signal Selection Default EFUSE_DIS_USB_JTAG = 0, EFUSE_DIS_PAD_JTAG = 0, EFUSE_STRAP_JTAG_SEL=1 0: JTAG signal from on-chip JTAG pins N/A 1: JTAG signal from USB Serial/JTAG controller E Note: 1. VDD_SPI voltage is determined either by the strapping value of GPIO45 or by VDD_SPI_TIEH. When R EFUSE_VDD_SPI_FORCE is 0, VDD_SPI voltage is determined by the strapping value of GPIO45; when EFUSE_VDD_SPI_FORCE is 1, VDD_SPI voltage is determined by VDD_SPI_TIEH. P2. The strapping combination of GPIO46 = 1 and GPIO0 = 0 is invalid and will trigger unexpected behavior. 3. ROM boot messages can be printed over U0TXD (by default) or GPIO17 (U1TXD), depending on the eFuse bit EFUSE_UART_PRINT_CHANNEL. 4. When both EFUSE_DIS_USB_SERIAL_JTAG and EFUSE_DIS_USB_OTG are 0, ROM boot messages will be printed to the USB Serial/JTAG controller. Otherwise, the messages will be printed to UART, controlled by GPIO46 and EFUSE_UART_PRINT_CONTROL. Specifically, when EFUSE_UART_PRINT_CONTROL value is: 0, print is normal during boot and not controlled by GPIO46. 1 and GPIO46 is 0, print is normal during boot; but if GPIO46 is 1, print is disabled.

If you choose to solder it, please apply the correct amount of soldering paste. · To ensure that the power supply to the ESP32-S3 chip is stable during power-up, it is advised to add an RC delay circuit at the EN pin. The recommended setting for the RC delay circuit is usually R = 10 k and IM C = 1 µF. However, specific parameters should be adjusted based on the power-up timing of the module and the power-up and reset sequence timing of the chip. For ESP32-S3's power-up and reset sequence timing diagram, please refer to Section Power Scheme in ESP32-S3 Series Datasheet.
