ESP8285 SMD Wifi RF System on a Chip SOC with Secure Boot and built in SPI 1MB Flash

Description

Introduction: Espressif’s ESP8285 delivers highly integrated Wi-Fi SoC solution to meet users’ continuous demands for efficient power usage, compact design and reliable performance in the Internet of Things industry. With the complete and self-contained Wi-Fi networking capabilities, ESP8285 can perform either as a standalone application or as the slave to a host MCU. When ESP8285 hosts the application, it promptly boots up from the flash. The integrated high-speed cache helps to increase the system performance and optimize the system memory. Also, ESP8285 can be applied to any microcontroller design as a Wi-Fi adaptor through SPI/SDIO or UART interfaces. ESP8285 integrates antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules. The compact design minimizes the PCB size and requires minimal external circuitries. Besides the Wi-Fi functionalities, ESP8285 also integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor and on-chip SRAM. It can be interfaced with external sensors and other devices through the GPIOs. Software Development Kit (SDK) provides sample codes for various applications. Espressif Systems’ Smart Connectivity Platform (ESCP) enables sophisticated features including: • Fast switch between sleep and wakeup mode for energy-efficient purpose • Adaptive radio biasing for low-power operation • Advance signal processing • Spur cancellation and RF co-existence mechanisms for common cell
