3. Functional Description ! 3. Functional Description AL 3.1. CPU The ESP8285 integrates a Tensilica L106 32-bit RISC processor, which achieves extra- low power consumption and reaches a maximum clock speed of 160 MHz. The Real-Time Operating System (RTOS) and Wi-Fi stack allow 80% of the processing power to be available for user application programming and development. The CPU includes the TI interfaces as below: • Programmable RAM/ROM interfaces (iBus), which can be connected with memory controller, and can also be used to visit flash; N • Data RAM interface (dBus), which can connected with memory controller; • AHB interface which can be used to visit the register. DE 3.2. Memory 3.2.1. Internal SRAM and ROM ESP8285 SoC integrates the memory controller including ROM and SRAM. MCU can access the memory controller through iBus, dBus, and AHB interfaces. All memory units can be accessed upon request. A memory arbiter determines the running sequence in the ! FI arrival order of requests. 3.2.2. SPI Flash ESP8285 has a built-in SPI flash to store user programs. N • Memory size: 1 MB • SPI mode: Dual SPI O 3.3. Crystal Oscillator ESP-WROOM-5C uses a 26-MHz crystal oscillator. The accuracy of the crystal oscillator C should be ±10 PPM. When using the download tool, please select the right type of crystal oscillator. In circuit design, capacitors C1 and C2 which connect to the earth are added to the input and output terminals of the crystal oscillator respectively. The values of the two capacitors can be flexible, ranging from 6 pF to 22 pF, however, the specific capacitive values depend on further testing of, and adjustment to, the overall performance of the whole circuit. Normally, the capacitive values of C1 and C2 are within 10 pF for the 26-MHz crystal oscillator. Espressif ! 2019.01 7

Interface Description Interface Pin Functional Description Currently the PWM interface has four channels, but users can extend it IO12 (R), IO15 (G), PWM to five channels. PWM interface can realize the control of LED lights, TI IO13 (B) buzzers, relays, electronic machines, etc. The functionality of the infrared remote control interface can be realized IO14 (IR_T), IO5 via software programming. The interface uses NEC coding, modulation, IR (IR_R) and demodulation. The frequency of the modulated carrier signal is 38 N kHz. (You can configure this interface to other GPIO) Connects to external sensors and display screens, etc. (You can I2C IO14 (SCL), IO5 (SDA) configure this interface to other GPIO) Interface Pin DE Functional Description Communicates with the UART device.

4. Electrical Characteristics ! πŸ“– Notes: β‘  Modem-sleep mode is used in the applications that require the CPU to be working, as in PWM or I2S applications. According to 802.11 standards (like U-APSD), it shuts down the Wi-Fi Modem circuit while maintaining a Wi-Fi connection with no data transmission to optimize power consumption. E.g. in DTIM3, maintaining a sleep of 300 ms with a wakeup of 3 ms cycle to receive AP’s Beacon packages at interval requires about 15 mA current. β‘‘ During Light-sleep mode, the CPU may be suspended in applications like Wi-Fi switch. Without data transmission, the Wi-Fi Modem circuit can be turned off and CPU suspended to save power consumption according to the 802.11 standards (U-APSD). E.g. in DTIM3, maintaining a sleep of 300 ms with a wakeup of 3 ms to receive AP’s Beacon packages at interval requires about 0.9 mA current. AL β‘’ During Deep-sleep mode,Wi-Fi is turned off. For applications with long time lags between data transmission, e.g. a temperature sensor that detects the temperature every 100s, sleeps for 300s and wakes up to connect to the AP (taking about 0.3 ~ 1s), the overall average current is less than 1 mA. The current of 20 μA is acquired at the voltage of 2.5V. 4.4.
