March 9 - STMicroelectronics has announced the ST87M01, an ultra-compact low-power IoT module with NB-IoT data communication and GNSS geo-location capabilities. The fully programmable, industrial-grade module is also said to integrate an advanced ST4SIM embedded SIM (eSIM) card. The company has already started to offer the ST87M01 prototype to major customers worldwide.

NB-IoT is an emerging technology in the Internet of Things, supporting cellular data connectivity for low-power devices over wide area networks. The ST87M01 is a fully programmable, industrial-grade module certified for LTE Cat NB2 NB-IoT, covering the global cellular mobile network communication bands and integrating advanced security features.

As one of the first 3GPP Release 15 compliant IoT cellular mobile network access chips, the ST87M01 offers greater multi-area LTE network coverage. The highly integrated native GNSS receiver features multiple navigation satellite system connections for more powerful and accurate positioning, while improving power savings while the NB-IoT sleeps.

The ST87M01 module is available in a 10.6mm x 12.8mm LGA package. Certified over the industrial temperature range (-40°C to +85°C), operating at less than 2µA in low-power mode and with a maximum transmit output power of +23dBm, it is suitable for a wide range of IoT devices requiring reliable low-power wide area network (LPWAN) connectivity, including smart meters, smart grids, smart buildings, smart cities and smart infrastructure, as well as industrial condition monitoring and factory It is also suitable for pet, child and elderly tracking and location, remote worker safety monitoring, asset tracking of equipment such as power tools and general smart logistics.

The ST87M01 is a fully programmable IoT platform that brings design flexibility to product developers, allowing users to implement simple application scenarios by simply embedding their own code directly into the module. The module can also be paired with a separate master microcontroller to implement many more complex use cases. To help developers design popular IoT use cases, ST offers a variety of protocol stacks, including IPv6, TCP / UDP, CoAP / LWM2M, MQTT, HTTP / HTTPS and TLS / DTLS. in addition, the ST87M01 supports standardized 3GPP AT commands, as well as ST's enhanced AT commands.

The module also integrates the ST4SIM embedded SIM (eSIM) card. The eSIM card has been certified to the latest industry standards, such as the recent GSMA eSA (Security Assurance) certification, further reducing the size of the device and improving security. The module also has a built-in advanced embedded security unit (eSE).

The ST87M01 can be used with a wide range of ST's technology products, including microcontrollers, AI solutions, sensors, actuators, PMUs, converters, interfaces, memories and other connectivity technologies.
