Low-Cost Wireless SoC Targets Consumer Products

A lower-cost variant of Nordic’s Bluetooth low-energy and proprietary 2.4-GHz system-on-chip (SoC) offers an identical feature and performance set to the existing nRF51822 and pin-to-pin capability but with a more economic half-sized 128-kbyte on-board flash memory. It can serve as a drop-in replacement for existing nRF51822-based designs where memory demands allow without risk or any EU/FCC requalification requirements. The nRF51822 128-kbyte variant offers the same multiprotocol radio and a 32-bit ARM Cortex-M0 based processor optimized for ultra-low-power (ULP) wireless applications. It will also be 100% on-air compatible with Nordic’s existing nRF24L series ICs. This new part will complement Nordic’s existing nRF51822 (256 kbytes) flash SoC by targeting the most price sensitive ULP wireless applications, typically high-volume consumer products such as entry-level PC mice and keyboards, smart-phone accessories, and toys.
