Indiesemic ISC-nRF52840-A An advanced multiprotocol ultra-low power BLE module V0.3

The nRF52840 is a mid-range Bluetooth^® Low Energy (LE) SoC that offers the lowest power consumption and smallest solution footprint in its class. This SoC features multi-core processing (Arm^® Cortex^®-M33™, Arm Cortex-M0+) and includes on-chip memory (RAM/ROM/Flash) sized to support a broad range of applications while maintaining cost-effectiveness. Typical applications include connected medical devices, asset tracking, human interface devices, metering systems, PoS readers, and crowdsourced location (CSL) tracking. Notably, the nRF52840 also includes a high-precision sigma-delta ADC, up to 32 GPIOs, and a QSPI for external memory (Flash or RAM) expansion, which is uncommon for this class of Bluetooth LE SoC.

The nRF52840 maintains Renesas’ leadership in lowest radio power consumption by leveraging its new low-power mode, enabling a radio transmit current of only 2.3mA at 0dBm and a radio receive current of 1.2mA. Furthermore, it supports an ultra-low hibernation current of 90nA, which extends the shelf-life of end-products shipped with a connected battery. For products that require extensive application processing, it also boasts an ultra-low active current of 34µA/MHz.

The nRF52840 typically requires only 6 external components, delivering best-in-class eBOM and offering the lowest solution cost and size. Its high accuracy on-chip RCX removes the need for an external, sleep mode crystal with most applications only requiring a 32MHz crystal. Package options include WLCSP (3.32mm x 2.48mm) and FCQFN (5.1mm x 4.3mm) offering an attractively small solution footprint. Additionally, it comes with a comprehensive suite of support tools, programming examples, Renesas’ professionally staffed support forum, and industry-leading customer technical support.
