4 Boot Configurations

Note: The content below is excerpted fromESP32-C6 Series Datasheet> SectionBoot Configurations via Strapping Pins and eFuses. For the strapping pin mapping between the chip and modules, please refer to Chapter8 Module Schematics. The module allows for configuring the following boot parameters through strapping pins and eFuse parameters at power-up or a hardware reset, without microcontroller interaction.

• Chip boot mode – Strapping pin: GPIO8 and GPIO9
• SDIO Sampling and Driving Clock Edge – Strapping pin: MTMS and MTDI
• ROM message printing – Strapping pin: GPIO8 – eFuse parameter: EFUSE_UART _PRINT _CONTROL and EFUSE_DIS_USB_SERIAL_JTAG_ROM_PRINT
• JTAG signal source – Strapping pin: GPIO15 – eFuse parameter: EFUSE_DIS_PAD_JTAG, EFUSE_DIS_USB_JTAG, and EFUSE_JTAG_SEL_ENABLE The default values of all the above eFuse parameters are 0, which means that they are not burnt. Given that eFuse is one-time programmable, once programmed to 1, it can never be reverted to 0. For how to program eFuse parameters, please refer toESP32-C6 Technical Reference Manual> ChaptereFuse Controller. The default values of the strapping pins, namely the logic levels, are determined by pins’ internal weak pull-up/pull-down resistors at reset if the pins are not connected to any circuit, or connected to an external high-impedance circuit. Table 4: Default Configuration of Strapping Pins Strapping Pin Default Configuration Bit Value MTMS Floating – MTDI Floating – GPIO8 Floating – GPIO9 Weak pull-up 1 GPIO15 Floating – To change the bit values, the strapping pins should be connected to external pull-down/pull-up resistances. If the ESP32-C6 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 Espressif Systems 12 Submit Documentation Feedback ESP32-C6-MINI-1 & MINI-1U Datasheet v1.3

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. The timing of signals connected to the strapping pins should adhere to thesetup timeand hold time specifications in T able5 and Figure4. Table 5: Description of Timing Parameters for the Strapping Pins Parameter Description Min (ms) tSU Setup timeis the time reserved for the power rails to stabilize be- fore the CHIP_PU pin is pulled high to activate the chip. 0 tH Hold timeis 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.

4.2 SDIO Sampling and Driving Clock Edge Control

The strapping pin MTMS and MTDI can be used to decide on which clock edge to sample signals and drive output lines. See T able7 SDIO Input Sampling Edge/Output Driving Edge Control.

default configurations.

4.3 ROM Messages Printing Control

During the boot process, ROM message printing is enabled if LP_AON_STORE4_REG[0] is 0 (default), and disabled if LP_AON_STORE4_REG[0] is 1. When ROM message printing is enabled, the messages can be printed to:

The strapping pin GPIO15 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 T able10 JTAG Signal Source Controlshows, GPIO15 is used in combination with EFUSE_DIS_PAD_JTAG, EFUSE_DIS_USB_JTAG and EFUSE_JTAG_SEL_ENABLE.

• Soldering the EPAD to the ground of the base board is not a must, however, it can optimize thermal performance. If you choose to solder it, please apply the correct amount of soldering paste. Too much soldering paste may increase the gap between the module and the baseboard. As a result, the adhesion between other pins and the baseboard may be poor.
• To ensure that the power supply to the ESP32-C6 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 kΩ and C = 1µF. 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-C6’s power-up and reset sequence timing diagram, please refer toESP32-C6 Series Datasheet> SectionPower Supply.

11.2 Module Placement for PCB Design

If module-on-board design is adopted, attention should be paid while positioning the module on the base board. The interference of the base board on the module’s antenna performance should be minimized. For details about module placement for PCB design, please refer toESP32-C6 Hardware Design Guidelines> Section Positioning a Module on a Base Board.

12 Product Handling

12.1 Storage Conditions

The products sealed in moisture barrier bags (MBB) should be stored in a non-condensing atmospheric environment of < 40 °C and 90%RH. The module is rated at the moisture sensitivity level (MSL) of 3. After unpacking, the module must be soldered within 168 hours with the factory conditions 25±5 °C and 60%RH. If the above conditions are not met, the module needs to be baked.

12.2 Electrostatic Discharge (ESD)

• Human body model (HBM): ±2000 V
• Charged-device model (CDM): ±500 V

12.4 Ultrasonic Vibration

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