MediaTek this week announced a new SoC designed for ultra-low-power autonomous IoT applications such as wearables, security sensors, and similar devices. The MT2621 SoC integrates basic computational capabilities, a modem that supports GSM/GPRS and NB-IoT, and a number of input/output interfaces. The MediaTek MT2621 features an Arm7 MCU featuring one core running at 260 MHz, 160 KB of SYSRAM and 4 MB of SIPRAM for microcontroller applications that do not require substantial computational resources or memory. To connect to the outside world, the MT2621 integrates a modem DSP, a wideband module (that supports ultra-low/low/mid bands defined by the 3GPP Rel-14), RF capabilities, and even an antenna that can work over existing GSM/GPRS (as well as upcoming NB-IoT networks). The SoC supports dual standby functionality...
