[performance parameters]
Available in (DIP and SOIC) 18-pin packages. Wide operating voltage 2.7V~5.5V, low operating current Typical current 3.7mA sub-serial port is 4800bpsVCC=5.0V?, high working speed 300bps~4800bps (any non-standard baud rate can be set by crystal frequency).
SP2328 is a universal asynchronous serial port UART extended ASIC designed with low-power CMOS technology. It can easily expand any existing 8-bit 16-bit and 32-bit microcontrollers such as AT89C52 and other original UART serial ports into 3 new ones. The full-duplex UART serial port has three baud rates up to 4800bps. All UART serial ports can receive data and transmit data independently. SP2328 is mainly used to solve most embedded microcontrollers. The UART serial port is specially designed for the special low-power UART serial port expansion chip. Compared with other multi-serial MCUs and UART expansion ASICs, the SP2328 multi-serial MCU solution has the following features without purchasing and learning new development. The tool emulator programmer and so on fully utilizes the original development tools and development environment. It can receive data and send data immediately after power-on. It does not need any initialization. The price is very high. The price is not as high as 35% of the similar products. It is very simple to debug the program of many similar products. It is recommended to use the software development kit provided by our company free of charge. It will be more than one hour can significantly reduce development costs and production costs to market.
characteristic:
1, the use of very simple does not require any software initialization settings to power up to work immediately.
2. Full-duplex working serial port and all sub-ports support full-duplex UART transmission mode.
3. The typical quiescent current after the power-saving mode enters the power-saving mode is about 0.5uA.
4. It can automatically wake up the receiving end of any serial port and wake up automatically when receiving data.
5, the output error is small, the data output baud rate error of each serial port is less than 0.25%.
6. Wide receiving range The data baud rate error of each serial port is less than 2.5% and can be received correctly.
7. The bit error rate is extremely low less than 10 9 (when the received data baud rate error is less than 2%).

Compared with traditional battery technology, Lithium Battery technology has drawn our attention because of its characteristics of high energy density, long cycle life, light weight and fast charging. Nowadays, they are the common power source for our daily power supply demands, such as golf carts. The volume of a lithium iron phosphate battery of the same specification and capacity is 2/3 of the volume of a lead-acid battery, and its weight is 1/3 of that of a lead-acid battery, and its energy density is several times that of a lead-acid battery.
Lithium batteries can be widely used for a variety of applications, including solar or wind energy storage, solar power system, telecom base station, camping, boat, fishing, recreational vehicles, golf carts and other applications. UFO lithium batteries are ready to be your reliable battery option.
-- Deep depth of discharge. Lithium batteries are designed to last longer with a deep depth of discharge. It enables some electronics such as high-tech and smart devices to work for a longer time.
-- Fast charging speed. When using lithium batteries for your electronic device, you can save time for charging and improve working efficiency.
-- Long service life. The lithium batteries provides up to 2000 cycle life with proper use. The features of less maintenance and longevity makes it a perfect option for power supply.
-- Wide temperature range. The lithium batteries can withstand extreme temperature. It can work in a cold winter or hot environment without battery failure. It is suitable for outdoor applications.
