ESP-12K Specification V1.0

1.PRODUCT DESCRIPTION

ESP-12K is a Wi-Fi module developed by Ensink Technology. The core processor

ESP32-S2 of this module is a highly integrated low-power Wi-Fi system-on-chip (SoC)

designed for the Internet of Things (IoT) , Mobile devices, wearable electronic devices,

smart home and other applications. ESP32-S2 has industry-leading low-power

performance and RF performance, supports IEEE802.11b / g / n protocol, integrates

Wi-Fi MAC, Wi-Fi RF and baseband, RF switch, RF Balun, power amplifier, low noise

Amplifier, etc.

The ESP32-S2 chip is equipped with Xtensa® 32-bit LX7 single-core processor, and its

operating frequency is up to 240 MHz. The chip supports secondary development

without the use of other microcontrollers or processors. The chip has 320 KB SRAM

and 128 KB ROM, and can be connected to flash and RAM through SPI / QSPI / OSPI

and other interfaces. ESP32-S2 supports a variety of low-power operating states to

meet the power consumption requirements of various application scenarios. The

unique fine clock gating function, dynamic voltage clock frequency adjustment function,

and RF output power adjustable function of the chip can achieve the best balance

between communication distance, communication rate and power consumption.

ESP32-S2 provides a wealth of peripheral interfaces, including SPI, I2S, UART, I2C,

LED PWM, LCD interface, Camera interface, ADC, DAC, touch sensor, temperature

sensor and up to 43 GPIO.It supports the expansion of PSRAM on the periphery of the

chip, and the ESP-12K module can be equipped with PSRAM. In addition, it includes a

full-speed USB On-The-Go (OTG) interface that can support the use of USB

communication.

ESP32-S2 has a variety of unique hardware security mechanisms. The hardware

encryption accelerator supports AES, SHA, and RSA algorithms. The RNG, HMAC and

Digital Signature (Digital Signature) modules provide more security features. Other

security features include flash encryption and secure boot (se-cure boot) signature

verification. The perfect security mechanism enables the chip to be perfectly applied to

various encryption products.
