Sony ALT1350 5G cellular IoT chip supports NTN connectivity, integrates sub-GHz and 2.4GHz radios

Sony ALT1350 is a new ultra-low-power 5G LPWA LTE-M/NB-IoT chip that supports Non-Terrestrial Networks (NTN) for satellite connectivity and also integrates sub-GHz and 2.4 GHz radios for short-range communication and improved efficiency.

The chip is comprised of an Arm Cortex-M4 microcontroller core as well as an Arm Cortex-M0+ always-on core for sensors and will be upgradable to 3GPP Release 17 to support higher bitrates for Cat-M1 (eMTC) and Cat-NB2 (NB-IoT). It also implements GNSS, cellular and wifi-based location, supports AI acceleration, and embeds a secure element for secure communication.

  • PCM/I2S audio,
  • LED, GPIOs
  • USIM or eIUCC
  • Auxiliary ADC
  • Capture/compare timer
• Security – Built-in Security Element
• Power Management – Integrated PMU with Voltage Regulators and Real-Time clock (RTC)
• Power Consumption – “optimized standby mode (eDRX) reduces power consumption by 80% when compared to the current generation and by 85% when using it to send short messages”
• Temperature Range – -40 to +85°C

Designed by Sony Semiconductor Israel, previously known as Altair Semiconductor, the chip aims to provide a hybrid solution with cellular, location, and short-range connectivity for smart meters, smart cities, trackers, connected health devices, and more.

Various optimizations and multiple radios enable a much lower power consumption of up to 85% when sending short messages with the company also claiming 4 times longer battery life for a typical device. The 802.15.4 radio also enables protocols such as Wi-Sun, U-Bus Air, and wM-Bus, as well as point-to-point and mesh technologies.

The Sony ALT1350 is currently sampling to “lead customers” and is expected to become commercially available during 2023. More details may be found on the product page.
