Based on nRF5340 Nordic Semiconductor wireless SoC with two Arm® Cortex®-M33 processors and advanced feature set, the ISP2053 module is ideally suited for LE Audio, professional lighting, advanced wearables, industrial, medical, and other complex IoT applications.

  • Low Energy tranceiver from Nordic Semiconductor nRF53
  • Bluetooth 5.2 LE Audio, Direction Finding and Long Range
  • BT Mesh, Thread, Zigbee, 802.15.4, ANT
  • NFC
  • Fully integrated RF Matching and Antenna
  • Integrated 32 MHz & 32 kHz Clocks
  • DC/DC converter with loading circuit
  • Power supply 1.7 to 5.5V
  • Extended Temperature -40 to +105 °C

Ultra-low power consumption and advanced power management enables battery lifetimes up to several years on a coin cell battery. Despite its exceedingly small size 8 x 8 x 1 mm, the module integrates decoupling capacitors, 32 MHz and 32.768 kHz crystals, load capacitors, DC-DC converters, RF matching circuit and antenna in addition to the wireless SoC. Combined with numerous Digital and Analog IOs, System Peripherals, high-speed SPI, QSPI, USB, up to 105 °C operating temperature, the ISP2053 is the most advanced fully certified 2.4 GHz low energy module available on the market.

The ISP2053 supports a large choice of wireless protocols:

  • Bluetooth Low Energy Central, Peripheral, Observer and Broadcaster roles.
  • Angle-of-arrival (AoA) and angle-of-departure (AoD) roles.
  • LE Audio, high-throughput 2 Mbps, Advertising Extensions and Long Range.
  • Mesh protocols like Bluetooth mesh, Thread and Zigbee that can be run concurrently with Bluetooth LE.
  • NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols.

The ISP2053 software platform is fully compatible with the Nordic Semiconductor nRF Connect SDK, which is offering a complete solution that integrates the Zephyr RTOS, protocol stacks, application samples and hardware drivers.

The ISP2053 development kit provides a complete hardware solution for prototyping, testing and programming with the maximum flexibility.
