Samsung has just announced their first NB-IoT solution with Exynos i S111 chipset with a single chip integrating an NB-IoT capable LTE modem, RF IC, an on-chip security sub-system, and a PUF (Physical Unclonable Function) security solution along with various components such as CPU, and SRAM. The chip apparently also integrates GNSS hardware with support for GPS, Galileo, etc…
Exynos i S111 specifications:
- CPU – Arm Cortex-M7 @ 200MHz
- On-chip Memory – 512KB SRAM
- Modem – LTE Release 14 NB-IoT
- GNSS – GPS, Galileo, GLONASS, BeiDou
- Interfaces / Peripherals – USI, UART, I2C, GPIO, eSIM I/F, SDIO (Host), QSPI(Single/Dual/Quad IO mode), SMC
- Security – eFuse, AES, SHA-2, PKA, Secure Storage, Security Sub-System, PUF
The chip is also said to features Samsung’s “advanced algorithms for wider coverage”. Many NB-IoT GPS trackers currently implement a two modules solution, so the latest Exynos chip should enable more compact designs.
Samsung did not publish numbers about power consumption, apart from the usual 10-year battery life for NB-IoT, and support for both PSM (Power Saving Mode) and eDRX (extended Discontinuous Reception) that enables nodes to sleep without regular network check-in for up to 40 minutes.
A few more details may be found in the product page.
