2021 Best Domestic Communication Chip
The Most Promising IC Design Company in 2021
Beijing Zhilianan Technology Co., Ltd. (MLINK) was established in 2013. It is an IC design company specializing in the research and development of cellular Internet of Things communication chips. The company's main products at this stage are 5G NB-IoT chips and 4G LTE communication chips.
We have a highly educated, highly professional and experienced team. The company's founders and core team graduated from famous domestic universities such as Tsinghua University and Zhejiang University. They have an average of more than 15 years of industry experience and rich R&D and management experience. The company's core R&D team previously had 15 years of experience in LTE communication chip design and participated in the development and mass production of the world's first TD-LTE chip.
Since its establishment, the company has always insisted on independent innovation of all core technologies, and has a large number of self-developed IPs and dozens of invention patents in communication algorithms, physical layer technologies, protocol stacks, radio frequency, etc. With the strong innovation ability of the R&D team, Zhilian'an successfully launched the world's smallest NB-IoT chip MK8020 and the first LTE Cat.1bis chip MK8110 for the "Extreme Data Transmission +" market in 2021.
Facing the 5G NR era, Zhilian'an will adhere to the development concept of "Smart IoT Security Innovation" and use a multi-faceted chip product array to meet the end-side chip needs of different market segments and promote the vigorous development of the 5G IoT communication industry!
MK8020
MK8020 is the second-generation NB-IoT communication chip independently developed by Beijing Zhilian'an Technology Co., Ltd. It adopts UMC55nm LP process, supports 3GPP LTE R13/R14 communication standards, and integrates MCU, baseband processor, analog unit, RF power amplifier unit and power management module on a single chip, truly realizing NB-IoT wide-area low-power IoT single-chip solution, aiming to provide highly competitive chip products for the cost- and power-sensitive IoT market (smart cities, smart homes, smart fire protection, smart buildings, wearable devices, etc.).
MK8020 supports 450~1000MHz, 1700~2200MHz frequency bands, and complies with the technical specifications and test requirements of China Mobile, China Telecom, and China Unicom NB-IoT modules. The integrated ARM Cortex-M4 processor cooperates with the hardware accelerator to implement NB-IoT physical layer and protocol stack tasks. At the same time, it can be opened to users for third-party development in OpenMCU mode. Users can flexibly call the various rich peripheral interfaces that come with the chip, thereby saving the cost of board-level MCU. The on-chip integration of DCDC, LDO, and DCXO helps users save board-level power and clock devices, greatly reducing BOM costs. At the same time, MK8020 is the first to adopt the world's smallest QFN 4.5mmx4.5mm packaging form, minimizing the size and complexity of downstream customers' module boards.
In terms of low power consumption, MK8020 can provide PSM current as low as 1uA, which is the industry-leading level. In DRX mode, the multi-level sleep-wake-up power domain technology integrated in the chip can reduce the standby current to hundreds of uA. The minimum supply voltage can be as low as 2.1V, which greatly improves the battery life of the device.
MK8020 further helps downstream customers design more competitive products by supporting many of the industry's most advanced features. The 32K XTALess function allows customers to save an external 32K crystal oscillator, significantly reducing module costs by 5~8%. Through the high-speed LPUART function, AT wake-up can be achieved at 9600 baud rate. The serial port can run up to 3Mbps baud rate in normal mode.
In addition, MK8020 can directly mount common sensor types in IoT applications, including voltage monitoring, current detection, motion sensing, smoke sensing, temperature and humidity, water level, locks, fingerprints, etc., through rich on-chip integrated interfaces such as SPI, I2C, UART, ADC, GPIO, etc., to enrich customers' product designs.
