Guangxin Microelectronics (Guangzhou) Co., Ltd. focuses on new energy, variable frequency motor control, low-power Internet of Things and automotive electronics industry, providing customers with differentiated microprocessor chips, fast charging and digital power management chips, analog and RF front-end chips, as well as low-power Internet of Things solutions, digital power solutions and motor control solutions.
Founded in September 2017, the company is headquartered in Huangpu District, Guangzhou, with subsidiaries or branches in Shanghai, Suzhou and Shenzhen, and has a comprehensive technical team and packaging, testing, mass production production management and operation team from product definition, chip design, software and hardware development to system solution design. Since its establishment, Guangxin Micro has successfully mass-produced a variety of products, which have been widely used in energy storage, industrial control, health care electronics, smart home, sensors and meters, and other fields.
Recently, when sorting out the case of Guangxin Micro, it was found that Guangxin Micro UM3506, a RISC-V architecture fast charging SOC chip, has been adopted by a variety of products, which is detailed for you below.
Guangxin UM3506 series SoC chips have full-featured SRC SNK DRP support capabilities and fully meet PD30，pd3.1 specification, support spr, epr (pd3.)1) mode, as well as the chunk mode of PD packets and 260bytes of long packets. In addition, UM3506 has 2 pairs of DP DM pins, which support BC, QC and other protocols.
UNICmicro UM3506 series products adopt a flexible programmable architecture combining software and hardware, and the TCPM TCPC layered architecture is used inside the chip, integrating a native TCPC-like front-end module, including digital logic and analog circuits for Type-C interface detection and control, block BMC codec at the PD PHY layer, and key functions with strict timing requirements in the PD protocol layer. At the same time, it has a built-in high-performance 32-bit MCU microprocessor core, large-capacity flash memory, SRAM memory, enhanced peripheral interfaces and rich system resources.
The UM3506 chip is committed to creating an open platform and a differentiated application design concept, so that designers can make more reasonable and effective use of the MCU resources on the chip, simplify the design of differentiated application software, shorten the system development time, and better ensure the real-time and reliability of the system, so as to perfectly realize the application development of PD+MCU.
The UM3506 family has multiple package sizes, namely QFN32 and QFN24, which are suitable for engineers to develop and design solutions according to the PCB size layout. The charging head network learned from Guangxin Micro that the UM3506 series adopts the RISC-V architecture, which is also the first in the industry to combine RISC-V and USB PD31 combined fast charging chip.
