Espressif Systems 13 Submit Documentation Feedback ESP32-S3-PICO-1 Series Datasheet v1.1 2 Pin Definition 2.3 Strapping Pins At each startup or reset, the ESP32-S3-PICO-1 requires some initial configuration parameters, such as in which boot mode to load the SiP, voltage of flash memory, etc. These parameters are passed over via the strapping pins. After reset, the strapping pins operate as regular IO pins. The parameters controlled by the given strapping pins at SiP reset are as follows: • Chip boot mode – GPIO0 and GPIO46 • VDD_SPI voltage – GPIO45 • ROM messages printing – GPIO46 • JTAG signal source – GPIO3 GPIO0, GPIO45, and GPIO46 are connected to the chip’s internal weak pull-up/pull-down resistors at chip reset. These resistors determine the default bit values of the strapping pins. Also, these resistors determine the bit values if the strapping pins are connected to an external high-impedance circuit. Table 2-2. Default Configuration of Strapping Pins Strapping Pin Default Configuration Bit Value GPIO0 Pull-up 1 GPIO3 Floating – GPIO45 Pull-down 0 GPIO46 Pull-down 0 To change the bit values, the strapping pins should be connected to external pull-down/pull-up resistances. If the ESP32-S3-PICO-1 is used as a device by a host MCU, the strapping pin voltage levels can also be controlled by the host MCU. All strapping pins have latches. At system reset, the latches sample the bit values of their respective strapping pins and store them until the chip is powered down or shut down. The states of latches cannot be changed in any other way. It makes the strapping pin values available during the entire chip operation, and the pins are freed up to be used as regular IO pins after reset. Regarding the timing requirements for the strapping pins, there are such parameters as setup time and hold time. For more information, see Table 2-3 and Figure 2-2. Table 2-3. Description of Timing Parameters for the Strapping Pins Parameter Description Min (ms) t SU Setup time is the time reserved for the power rails to stabilize before the CHIP_PU pin is pulled high to activate the chip. 0 t H Hold time is the time reserved for the chip to read the strapping pin values after CHIP_PU is already high and before these pins start operating as regular IO pins. 3 Espressif Systems 14 Submit Documentation Feedback ESP32-S3-PICO-1 Series Datasheet v1.1 2 Pin Definition Strapping pin VIL_nRST VIH t SU t H CHIP_PU Figure 2-2.

The ROM messages printing to UART or USB Serial/JTAG controller can be respectively disabled by configuring registers and eFuse. For detailed information, please refer to ESP32-S3 Technical Reference Manual > Chapter Chip Boot Control. 2.3.4 JTAG Signal Source Control The strapping pin GPIO3 can be used to control the source of JTAG signals during the early boot process. This pin does not have any internal pull resistors and the strapping value must be controlled by the external circuit that cannot be in a high impedance state. As Table 2-6 shows, GPIO3 is used in combination with EFUSE_DIS_PAD_JTAG, EFUSE_DIS_USB_JTAG, and EFUSE_STRAP_JTAG_SEL. Table 2-6.

ESP32-S3-PICO-1 Peripheral Schematics To ensure that the power supply to ESP32-S3-PICO-1 is stable during power-up, it is advised to add an RC delay circuit at the CHIP_PU pin. The recommended setting for the RC delay circuit is usually R = 10 kΩ and C = 1 µF. However, specific parameters should be adjusted based on the power-up timing of the SiP 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 ESP32-S3 Series Datasheet > Section Power Supply.

The SiP is rated at the moisture sensitivity level (MSL) of 3. After unpacking, the SiP must be soldered within 168 hours with the factory conditions 25±5 °C and /60%RH. If the above conditions are not met, the SiP needs to be baked. 7.2 Reflow Profile Solder the SiP in a single reflow. 50 150 0 25 1 ~ 3 ℃/s 0 200 250 200 –1 ~ –5 ℃/s Cooling zone 100 217 50 100 250 Reflow zone 217 ℃ 60 ~ 90 s Temperature (℃) Preheating zone 150 ~ 200 ℃ 60 ~ 120 s Ramp-up zone Peak Temp. 235 ~ 250 ℃ Soldering time > 30 s Time (sec.)

Reflow Profile 7.3 Ultrasonic Vibration Avoid exposing Espressif SiPs to vibration from ultrasonic equipment, such as ultrasonic welders or ultrasonic cleaners. This vibration may induce resonance in the in-SiP crystal and lead to its malfunction or even failure. As a consequence, the SiP may stop working or its performance may deteriorate.
