ISC-nRF54L15-A Bluetooth 6.0 Multiprotocol Module with Nordic nRF54L15, Integrated Antenna and FCC/CE/WPC Certification
The ISC-nRF54L15-A is a Made-in-India, ultra-low-power Bluetooth 6.0 wireless module built around the Nordic Semiconductor nRF54L15 SoC. Designed and manufactured by IndieSemiC, the compact 36-pin castellated SMD module measures approximately 15.06 x 20.40 mm and integrates a PCB trace antenna for simplified wireless product development. It supports Bluetooth Low Energy, Bluetooth Mesh, Thread, Zigbee, Matter, proprietary 2.4 GHz communication and NFC-A, enabling a single hardware platform to support multiple IoT, smart-home and connected-device architectures through firmware configuration.
At its core, the nRF54L15 combines a 128 MHz Arm Cortex-M33 processor with TrustZone and FPU, 1500 kB RRAM, 256 kB RAM and an integrated RISC-V coprocessor. The multiprotocol radio supports Bluetooth 6.0 Channel Sounding, BLE data rates from 0.125 Mbps to 2 Mbps and proprietary 2.4 GHz communication up to 4 Mbps. Adjustable RF output from -8 dBm to +8 dBm, receiver sensitivity down to -103 dBm in Coded PHY mode and hardware AES/ECB/CCM/AAR acceleration support secure, low-power wireless applications.
For embedded integration, the ISC-nRF54L15-A provides 29 GPIO pins across 3 power domains, up to 5 EasyDMA-enabled serial interfaces, I2S, PDM, an 8-channel ADC, PWM, timers, quadrature decoders, Global RTC, temperature sensing and programmable peripheral interconnect resources. It operates from 1.7 V to 3.5 V and supports temperatures from -40 C to +85 C. Typical measured current is approximately 1.19 uA in System OFF mode and approximately 219.6 uA during BLE advertising at +4 dBm with an approximately 100 ms interval. FCC, CE and WPC ETA certifications support module-level integration for products targeting multiple markets, while final-product regulatory compliance remains the responsibility of the equipment manufacturer.
