Description

The IndieSemiC ISC-nRF52840-A module delivers a production-ready wireless node centered on the feature-rich Nordic Semiconductor nRF52840 system-on-chip. Its dual-core architecture separates application logic on the Cortex-M33 from real-time radio protocol tasks on the Cortex-M0+, enabling efficient handling of complex stacks like Matter over Thread or Zigbee 3.0 without compromising RF performance.

Engineered for minimal external component count, the module simplifies PCB design while offering best-in-class power efficiency. The integrated high-precision ADC and ample GPIOs allow direct connection to analog sensors, buttons, and displays, making it ideal for Human Interface Devices (HID), medical monitors, and smart home endpoints. Secure key storage and secure boot features provide a foundation for robust device identity and over-the-air (OTA) firmware updates.

Key Features

  • Dual-core processing with Arm Cortex-M33F application core and Cortex-M0+ configurable MAC core, both running at 64MHz.
  • Supports latest IoT standards: Bluetooth 5.4 LE, Bluetooth Mesh, Matter, Thread, and Zigbee 3.0 for future-proof connectivity.
  • Industry-leading ultra-low power states: 90nA hibernation current and 34µA/MHz active current maximize battery life.
  • High-performance RF link with -97dBm receive sensitivity and up to +6dBm programmable transmit output power.
  • On-board memory includes 256KB RAM and 1MB Flash, expandable via QSPI interface for data logging or complex applications.
  • Integrated 8-channel, 15-bit sigma-delta ADC for precise analog sensor measurements without external components.
  • Built-in PCB antenna simplifies design and reduces BOM, with support for external antenna options if required.
  • WPC (Wireless Planning & Coordination Wing) ETA certification ensures legal operation for commercial products in India.

Applications

  • Smart home automation endpoints (lights, switches, sensors) compatible with Matter and Thread ecosystems.
  • Connected medical devices and wearable health monitors leveraging BLE's low-power profile.
  • Asset tracking beacons and indoor positioning systems using Bluetooth direction finding.
  • Human Interface Devices (HID) like wireless keyboards, mice, and game controllers.
  • Industrial IoT telemetry sensors and meter reading systems with Mesh network reliability.
  • PoS (Point of Sale) readers and secure payment terminals.

Frequently Asked Questions

What development frameworks are supported for programming the ISC-nRF52840-A module?

The module is fully compatible with the Nordic Semiconductor nRF Connect SDK (NCS) and Zephyr RTOS, which provide official support for Bluetooth LE, Mesh, Matter, and Thread. For prototyping, you can also use the Arduino IDE with community-supported cores or the Segger Embedded Studio. Development requires a compatible Segger or Nordic Semiconductor's DK programmer to connect via the module's SWD debug pins for flashing and debugging your application firmware.

How do I configure the module for Bluetooth Mesh or Matter over Thread networks?

For Bluetooth Mesh, use the nRF Mesh mobile app or nRF Connect SDK examples to provision the device as a node. For Matter over Thread, you must first commission the device onto a Thread network using a Thread Border Router. This involves building a firmware image with the Matter stack, flashing it via SWD, and then using the Matter commissioning tool on a smartphone or chip-tool to add the device to your fabric, which requires the correct DAC/PAI certificates programmed into the module's secure storage.

What is the power supply requirement and how do I achieve the lowest sleep current?

The module typically operates at 3.3V. To achieve the specified 90nA hibernation current, you must correctly configure the nRF52840's System OFF or System ON idle mode with RAM retention disabled in your firmware. Ensure all unused GPIOs are configured as inputs with pull-ups/downs disabled and that external circuitry connected to the module does not create leakage paths. Power measurements should be taken with a high-precision ammeter in series with the 3.3V supply line while the device is in the target low-power mode.
