Ensure the security and visibility of your assets with IN100 and PIC18F57Q43

NanoBeacon Click is based on the IN100, a versatile and compact part of InPlay's NanoBeacon™ SoC product family that operates as a Bluetooth low energy beacon in the 2.4GHz frequency band. Packed with advanced features, this SoC boasts an efficient and configurable state machine, ensuring optimal performance. It incorporates non-volatile memory for storing user-defined data payload and a data SRAM for dynamic data storage. The IN100 further includes an analog-to-digital converter, a powerful security engine supporting AES-128 and EAX encryption, and a True Random Number Generator (TRNG) for enhanced security. It also offers a unique proprietary beacon mode, available in either the 2.4GHz ISM frequency band or the MedRadio frequency bands. Enclosed in a small QFN package, this device offers a seamless and secure solution for a wide range of Industrial Internet of Things (IIoT) applications. With its user-friendly design, this device eliminates the need for complex Bluetooth-related software programming. Once configured, it automatically transmits either BLE advertising or proprietary-format advertising packets, allowing for effortless operation. The IN100 features two types of built-in memory: a 4Kb OTP memory for storing user advertising data payload, security key, and predefined register settings, and a 4KB SRAM for dynamic advertising data storage. The SRAM retains data in Sleep mode while only the always-on (AON) domain remains active. The IN100 offers an extensive array of supported sensor interface protocols, ensuring compatibility with a wide

range of sensor devices. Additionally, it supports popular beacon formats such as iBeacon, Eddystone, and even custom beacon formats, allowing for seamless integration into various ecosystems. This Click board™ communicates with MCU using the UART interface with commonly used UART RX and TX pins. It operates at 115200 bps by default configuration to transmit and exchange data with the host MCU. Also, the IN100 enables on-the-fly changes to the advertising data payload and control mode through its UART interface. While UART communication can be used as the IN100's primary mode of communication with the MCU, an additionally supported interface, the I2C 2-wire interface, can be used to communicate with additional external sensors connected to this Click board™ via its onboard stacking headers of the mikroBUS™ socket. As previously stated, the OTP memory stores the user's advertising data payload, security key, and predefined register settings. This memory is programmed only once before usage. Switch the OTP SEL switch to ON to program the desired configuration into the device's one-time programmable memory. This action will effectively 'burn' the configuration into the tag's OTP memory. After the configuration has been burned, the power supply to the Click board™ must be disconnected and reconnected (or reset the board) to initiate the tag's execution based on its programmed behavior. This Click board™ comes with a miniature coaxial U.FL series antenna connector, which allows connecting the appropriate antenna for improved range and

received signal strength. Besides the UART pins, the NanoBeacon Click also employs other pins of the mikroBUS™ socket to enhance its functionality. For example, the EN pin is utilized as a chip-enable pin, the AN pin for external analog sensor measurements, one DQ pin as a general-purpose I/O pin, and the device RESET button which can be used to reset the device to its default settings, ensuring efficient and reliable operation. Two orange LED indicators, GP6 and GP7, can be used for optional user-configurable visual indications of some operational states. Additionally, it incorporates two low-leakage load switches for convenient power control of external circuitry and sensor ICs available for users on unpopulated SW0-SW1 pins, SW0 for the external sensor's power supply, and SW1 for its ground connection, respectively. This Click board™ can only be operated with a 3.3V logic voltage level. Also, the IN100 can use a backup supply voltage, selected via BATTERY switch, from a connected coin-cell battery on the back of the board if you need the Click board™ to be a standalone device. For additional low power consumption, unsolder the CT jumper on the back side of the board, which turns off the power LED indicator and reduces power consumption. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
