RN1723 Overview
rn1723.png
The RN1723 is a stand-alone, embedded 802.11 b/g Wireless Local Area Network (WLAN) module. The module incorporates an on-board TCP/IP networking stack, cryptographic accelerator, power management subsystem, real-time clock, versatile sensor interface, 2.4 GHz transceiver, and RF power amplifier (see figure below):

The RN1723 provides cost and time-to-market savings as a self-contained, Internet-enabling solution. The module has been designed to provide you with a simple Wi-Fi solution that features:
  • Ultra-low power for years of battery life
  • Firmware configurable transmit power: 0dBm to +12dBm
  • Hardware interfaces: UART and SPI Slave
  • Supports SoftAP and Infrastructure networking modes
  • RF pad for external antenna
  • User programmable GPIO & ADCs
  • Real-time clock for time-stamping, auto-sleep, and auto-wakeup modes
  • Run directly from batteries or regulated power supplies
  • ASCII interface for ease of development
  • Over the air firmware upgrade
  • WPS Mode for secure wireless setup
  • Secure Wi-Fi authentication schemes (WEP/WPA/WPA2)
  • Advanced SSL/TLS security (running on external PIC® MCU)
  • Full on-board TCP/IP/UDP stack (no external drivers required)
  • Efficient active and standby modes:
    • 4µ Sleep mode
    • 15mA DOZE (Standby) mode
    • 40mA Receive
    • 120mA Transmit

MCU Interface (Basic)

In the simplest configuration, the module requires only power, ground, and UART Transmit (TX) and Receive (RX) connections. The RN1723 module can interface to low-cost microcontrollers using only two wires, UART TX and RX.

Note: The Module RESET connection is also recommended to be able to synchronize the MCU firmware with the Module as shown.
