altUltra low power (ULP) RF specialist Nordic Semiconductor ASA (Oslo, Norway) has announced the availability of a lower cost variant of its nRF51822 Bluetooth® low energy and proprietary 2.4GHz SoC (System-on-Chip) that will offer an identical feature, peripherals, and performance set but half the flash memory at 128kB (instead of 256kB) and be based on the same nRF51 Series technology platform. This means it will offer the same multiprotocol radio and a 32-bit ARM Cortex-M0 based processor optimized for ultra-low power wireless applications and deliver -92.5dB RX sensitivity in Bluetooth low energy mode; up to +4dBm output power in all modes; up to 9.5dBm improvement in link budget compared to previous generations of class-leading Nordic chips, and sub-10mA peak currents running off a 3V coin cell battery for months or years of battery life (depending on the application).
