Technical Blog

The MediaTek MT6877 (see Figure 1-1) integrates Bluetooth, FM, WLAN, and GPS modules and is a highly integrated baseband platform that integrates a modem and application processing subsystem to support LTE/5G/NR and C2K smartphone applications. The chip integrates two Arm® Cortex-A78 cores running at up to 2.4 GHz, six Arm® Cortex-A55 cores running at up to 2.0 GHz, and a powerful multi-standard video codec. In addition, an extensive set of interfaces and connectivity peripherals for connecting cameras, touchscreen displays, and UFS/MMC/SD cards are included. The application processors are multi-core Arm® Cortex-A78, Arm® Cortex-A55 with NEON engine, which provides the processing power needed to support the latest OpenOS and its demanding applications such as web browsing, email, GPS navigation, and gaming. All content can be viewed on a high-resolution touchscreen display, and 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, multiple decoders and encoders.

The combination of high-performance CPU, DSP, and hardware coprocessors provides a robust 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 MT6877 hardware also embodies Wireless Communication devices, including WLAN, Bluetooth, and GPS. The MT6877 hardware integrates four advanced radio technologies into a single chip, providing the industry's best and most convenient connectivity solution. Improves the overall quality of simultaneous transmission of voice, data, and audio/video on mobile phones and media tablets. The small footprint and low power consumption greatly reduce PCB layout resources.
