Murata claims that its cellular IoT solutions will deliver high benefits in terms of size as well as power and cost efficiency. The CAT-M/NB1 module with GNSS will be the world’s smallest form factor solution enabling new possibilities and applications that were not possible before. Furthermore, the solutions will reduce time to market because of their simplicity and high level of integration, the company said.

Murata selected Altair’s feature-rich and highly compact ALT1250 chipset to power its Type 1SE and Type 1SC end device and module, respectively. The ALT1250 is the most integrated and advanced chipset that supports CAT-M1 and NB1. It incorporates Altair’s OneSKUTM RF technology to enable multiple LTE band combinations, as well as CAT-M1 and NB1 functionality with a single hardware design. Additional features include GNSS and cellular-based positioning engines, an IoT-optimized security framework, and integrated VoLTE support. The ALT1250’s ultra-low power consumption – including both 3GPP power saving mode (PSM) and eDRX – increases battery life to up to 15 years in certain use cases. The ALT1250 will be firmware-upgradable to support NB2.    


The CAT-M1/NB1 module measuring 11.1×11.4×1.4 mm, which is less than half the area of many other commercial solutions; the 1SC module is the flexible option. IoT solution providers can pair this module with any of the 700+ part numbers of STMicroelectronics’ STM32 MCU portfolio to address a wider range of IoT applications.

Measuring 15 x 17 x 1.4 mm, the Type 1SE device is the optimized choice, with minimum power consumption and size. The STM32L462REY6 is an ultra-low-power MCU which features an Arm Cortex-M4 running at 80MHz with 512KB Flash and 160 KB SRAM. The STM32L4 MCU series features the best-in-class ultra-low-power architecture available on the market with several ultra-low-power modes, including a Standby mode that consumes only 450nA while retaining 16 KBytes of SRAM and RTC running; a super-optimized Shutdown mode draws only 8nA. The ST33J2M0 Secure Microcontroller is based on the 32-bit Arm SecurCore SC300 processor, features 2 Mbytes of embedded flash to store securely sensitive data, hardware accelerators for advanced cryptographic functions and additional security features to help protecting against advanced form of attacks.

Murata and Altair will showcase the new module and device at Mobile World Congress in Barcelona, Spain, from February 26 to March 1 and at Embedded World in Nuremberg, Germany from February 27 to March 1.
1SC Type samples will be available in March and 1SE Type samples are expected in June.
