Mediatek reveals mt2621 soc for iot with integrated modem.

MediaTek announced this week a new SoC designed for ultra-low power stand-alone IoT applications such as wearables, security sensors, and similar devices. The MT2621 SoC integrates basic computing capabilities, a modem that supports GSM / GPRS and NB-IoT, and a number of input / output interfaces.

SoC MT2621 is a new low power SoC for ioT applications

The MediaTek MT2621 is an ARM v7 MCU chip with a core that runs at 260 MHz, 4 MB of built-in Flash, and 160 KB of PSRAM for microcontroller applications that do not require substantial computational resources or memory. To connect to the outside world, the MT2621 integrates a DSP modem, a broadband module (which supports 3GPP Rel-14 defined ultra-low / low / medium bands), RF capabilities, and even an antenna that can work on existing GSM / GPRS networks (as well as nearby NB-IoT networks).

The SoC supports dual standby functionality and can operate on both networks simultaneously. To connect to local wireless peripherals, the MT2621 can use Bluetooth 4.2. The chip also has an LCM interface for connecting LCDs, an interface for a camera, and audio interfaces for connecting a speaker and a microphone.

The MT2621's highly integrated design allows device manufacturers to minimize the number of additional components, simplifying development cycles and reducing BOM costs. In addition, this MediaTek chip was conceived to be efficient in energy consumption, which would allow a long battery life, something crucial for battery-powered applications, including devices to monitor health, fitness or health, sensors IoT security, smart meters and industrial equipment.

Device manufacturers will also have to program their software for the MT2621 that can run a custom MCU variant of Linux, but not Android or similar operating systems.
