The MT2625 IoT chip is relatively popular now. Many engineers are developing the MT2625 platform. The following is the specification book downloaded from the hacker.com forum, and now I will share it with you.
The mt2625 is a highly integrated chipset featuring an application processor, a low power multi-band narrowband IoT transceiver and a power management unit (pmu).
The mt2625 is arm based with a floating point microcontroller unit (mcu) integrated with 4mb psram and 4mb flash. mt 2625 also supports including uart, i2c, spi, i2s, pwm, sdio, adc, usb,

Kiba and Useem.
The nb-iot transceiver contains 3gpp r13/r14 radio, baseband and mac, designed to meet the requirements of low power and extended battery life.

There are also some MT2625 reference design materials here

The MT2625 is the first NB-IoT dedicated chip carefully crafted by MediaTek. integrated on the same chip platform. The high level of integration not only leads to a smaller package size, but also helps to reduce chip costs and speed up time-to-market for cost-sensitive and small-scale IoT devices. In addition, continuing the consistent advantages of MediaTek chips in overall power consumption control, MT2625 loads MediaTek's unique low-power technology on components such as MCU and PSRAM, so that IoT devices using this solution can be used with rechargeable batteries. Long standby time, meeting the requirements of low-power wide-area IoT.

MT2625 is the first NB-IoT (Narrowband Internet of Things) system-on-chip (SoC) launched by MediaTek, and it has joined hands with China Mobile to create the industry's smallest (16mm X 18mm) NB-IoT general-purpose module. IoT devices offer low-power and cost-effective solutions. The solution supports 450MHz-2.1GHz full-band operation of 3GPP NB-IoT (R13 NB1, R14 NB2), suitable for static or mobile IoT applications such as smart home, logistics tracking, and smart meter reading worldwide
