Functional Description 4.1 MCU ESP8266EX contained in the ESP8266-12H integrates Tensilica L106 32-bit micro controller (MCU) and a 16-bit RSIC. The CPU clock speed is 80 MHz and can reach a maximum value of 160 MHz. The system can readily run a Real Time Operating System (RTOS). Currently, the Wi-Fi stack only takes up 20% of CPU time. The remaining CPU time (80% of total MIPS) can be used for user application. The MCU can work in conjunction with the other parts of the chip through the following interfaces.  Programmable RAM/ROM interface (iBus) that connects to memory controller and can access the external flash.  Data RAM interface (dBus) that connects to memory controller.  AHB interface that accesses the register.

Shenzhen Hysiry Technology Co.,Ltd T：0755-23596457 8 / 14 4.2 Memory 4.2.1 Internal SRAM and ROM ESP8266EX Wi-Fi SoC integrates memory controller including SRAM and ROM. MCU can access the memory controller through iBus, dBus, and AHB interfaces. All these interfaces can access ROM or RAM units. A memory arbiter determines the running sequence in the arrival order of requests. According to our current version of SDK, SRAM space available to users is assigned as below.  RAM size < 50 kB, that is, when ESP8266EX is working in Station mode and connects to the router, available space in Heap + Data sector is around 50 kB.  There is no programmable ROM in ESP8266EX, therefore, user program must be stored in the SPI flash integrated into the ESP8266-12H. 4.2.2 SPI Flash  ESP8266EX supports SPI flash. Theoretically speaking, ESP8266EX can support up to 16 MB SPI flash.  ESP8266-12H. currently integrates 8 Mbit SPI flash memory. ESP8266-12H supports these SPI modes: Standard SPI, DIO (Dual I/O), DOUT (Dual Output), QIO (Quad I/O) and QOUT (Quad Output). 4.3 Interface Description Table -2. Interface Description Interface Pin Functional Description SPI IO12(MISO),IO13(MOSI), IO14(CLK),IO15(CS) S3 can control SPI Slave as a Master or communicate with Host MCU as a Slave. In overlap mode, S3 can share the SPI interface with Flash, shifted by different CS signals. PWM Any available GPIO (EXCEPT GPIO16) Currently the demo provides 4 PWM channels (users can extend to 6 channels). PWM interface can realize the control of LED lights, buzzers, relays, electronic machines, etc. IR Any available GPIO (EXCEPT GPIO16) The functionality of Infrared remote control interface can be implemented via software programming. NEC coding, modulation, and demodulation are used by this interface. The frequency of modulated carrier signal is 38KHz. ADC TOUT ESP8266EX integratesa 10-bit precision SARADC. ADC_IN interface is used to test the power supply voltage of VDD3P3(Pin 3 and Pin 4), as well as the input voltage of TOUT (Pin 6). It can be used in sensors application. I2C IO14(SCL), IO2(SDA) Any available GPIO(EXCEPT GPIO16) Can connect to external sensor and display, etc.

According to802.11 standards (like U-APSD), it saves power to shut down the Wi-Fi Modem circuit whilemaintaining a Wi-Fi connection with no data transmission. E.g. in DTIM3, to maintain a sleep 300mswake 3ms cycle to receive AP’s Beacon packages, the current is about 15mA. ②: During Light-Sleep, the CPU may be suspended in applications like Wi-Fi switch. Without datatransmission, the Wi-Fi Modem circuit can be turned off and CPU suspended to save poweraccording to the 802.11 standard (U-APSD). E.g. in DTIM3, to maintain a sleep 300ms-wake 3mscycle to receive AP’s Beacon packages, the current is about 0.9mA. ③: Deep-Sleep does not require Wi-Fi connection to be maintained. For application with long timelags between data transmission, e.g. a temperature sensor that checks the temperature every 100s,sleep 300s and waking up to connect to the AP (taking about 0.3~1s), the overall average current isless than 1mA. 5.2 RF Performance Table -5.
