For the strapping pin mapping between the chip and modules, please refer to Chapter 8 Module Schematics. The chip 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: GPIO26, GPIO27, and GPIO28 • SDIO sampling and driving clock edge – Strapping pin: GPIO25 and MTDI • ROM message printing – Strapping pin: GPIO27 – eFuse parameter: EFUSE_UART_PRINT_CONTROL and EFUSE_DIS_USB_SERIAL_JTAG_ROM_PRINT • JTAG signal source – Strapping pin: GPIO7 – 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 to ESP32-C5 Technical Reference Manual > Chapter eFuse 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 4-1. Default Configuration of Strapping Pins Strapping Pin Default Configuration Bit Value GPIO25 Floating – GPIO26 Floating – GPIO27 Pull-up 1 GPIO28 Pull-up 1 GPIO7 Floating – MTMS Floating – MTDI Floating – To change the bit values, the strapping pins should be connected to external pull-down/pull-up resistances. Espressif Systems 13 Submit Documentation Feedback ESP32-C5-MINI-1 Datasheet v1.0 4 Boot Configurations All strapping pins have latches. At Chip 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. For details on Chip Reset, see ESP32-C5 Technical Reference Manual > Chapter Reset and Clock. The timing of signals connected to the strapping pins should adhere to the setup time and hold time specifications in Table 4-2 and Figure 4-1. Table 4-2. 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 Strapping pin V IH_nRST V IH t SU t H CHIP_PU Figure 4-1.

In Joint Download Boot 1 mode, users can download binary files into flash using UART0 or SDIO interfaces. It is also possible to download binary files into SRAM and execute it from SRAM. 4.2 SDIO Sampling and Driving Clock Edge Control The strapping pin GPIO25 and MTDI can be used to decide on which clock edge to sample signals and drive output lines.

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.

ESP32-C5-MINI-1 Peripheral Schematics • Please control the voltage levels of strapping pins. For more details, please refer to Chapter 4 Boot Configurations. • 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-C5 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 = 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-C5’s power-up and reset sequence timing diagram, please refer Section 4.5 Chip Power-up and Reset.

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 12.3 Reflow Profile Solder the module in a single reflow. 50 100 0 150 200 250 200 100 50 150 250 Time (s) 217 25 Preheating 150 – 200 °C 60 – 120 s Ramp-up 25 – 150 °C 60 – 90 s 1 – 3 °C/s Soldering ＞ 217 °C 60 – 90 s Peak temperature: 235 – 250 °C Peak time: 30 – 70 s Soldering time: ＞ 30 s Solder: Sn-Ag-Cu (SAC305) lead-free solder Temperature (°C) 180 230 Cooling ＜ 180 °C –5 ~ –1 °C/s Figure 12-1.
