The MediaTek MT6897 device is a highly integrated baseband platform that includes a modem and application processing subsystem to support LTE/LTE-a/NR-Sub6 and C2K smartphone applications. The chip integrates four Arm®Makalu cores, four Arm®Klein cores, and a powerful multi-standard video codec. In addition, a wide set of interfaces and connectivity peripherals includes interfaces with cameras, touchscreen monitors and UFS/MMC/SD cards. The application processors, the multi-core Arm®Makalu and Arm®Klein are equipped with the NEON engine, which provides the necessary processing power to support the latest OpenOS and its demanding applications such as web browsing, email, GPS navigation and gaming. All of this is displayed on a high-resolution touchscreen, and the graphics are enhanced with 2D and 3D graphics acceleration. Multi-standard video accelerators and advanced audio subsystems are also integrated to provide advanced multimedia applications and services, such as streaming audio and video, with a large number of decoders and encoders. The combination of high-performance CPU, DSP, and hardware coprocessor provides a powerful modem subsystem capable of supporting NR Sub6, LTE Cat 18, Category 24 HSDPA downlink, and Category 7 HSUPA uplink data rates, as well as Category 12 GPRS, EDGE. The MT6897 also implements Wireless Communication devices, including WLAN, Bluetooth, and GPS. The MT6897 leverages the four advanced radio technologies of the Combo chipset to provide the industry's best and most convenient connectivity solution. The overall quality of simultaneous voice, data, and audio/video transmission on mobile phones and media tablets is improved. The small footprint and low power consumption greatly reduce the PCB layout resources.
