  "textContent": "Nordic Semiconductor’s nRF54LS05A and nRF54LS05B are entry-level, ultra-low-power Bluetooth Low Energy (LE) Arm Cortex-M33 microcontrollers designed to be used as the main wireless SoC in simple applications such as sensors, tags, beacons, remotes, and PC peripherals, or operate as a Bluetooth LE companion device in more advanced products. Both SoCs are clocked at 128 MHz, feature Nordic’s 4th-generation Bluetooth LE radio, analog/digital interfaces, and advanced security. They also come with 0.5 MB of Non-Volatile Memory (NVM), and the only difference is that the nRF54LS05A is equipped with 64 KB of RAM, while the nRF54LS05B offers 96 KB. Nordic Semi nRF54LS05A/B specifications: CPU Arm Cortex-M33 core @ 128 MHz Performance – 250 CoreMark/mA @ 3V, 500 CoreMark Memory nRF54LS05A – 64 KB RAM nRF54LS05B – 96 KB RAM Storage – 508 KB NVM Wireless Bluetooth LE – 1 Mbps, 2 Mbps 2.4 GHz proprietary – GFSK: 4 Mbps, 2 Mbps, 1 [...]\n\nThe post Nordic Semi unveils nRF54LS05A and nRF54LS05B entry-level, ultra-low-power Bluetooth LE SoCs appeared first on CNX Software - Embedded Systems News.",
