In order to improve energy efficiency, countries are accelerating the construction of smart grids and promoting smart meters to meet the rising demand for electricity. At the same time as fast-tracking smart meter applications, meter developers, manufacturers of metaware for them and even end-users are focusing on technologies and products that will make smart meters more energy-efficient, with a view to achieving smart controls in the same way that they will be able to obtain an energy-saving, safe and reliable meter product. As a supplier of high-performance, energy-efficient silicon programmes, the ansemian semiconductor possesses a variety of technologies and products that contribute to energy efficiency and can help smart meter manufacturers design products that are more efficient in terms of power efficiency。
Smart meter products need to save electricity
At present, countries in europe and the united states are experimenting with the use of advanced technologies to contain peaks in electricity consumption, and smart meters provide a rich, real-time value-added service for smart electricity while serving as a clearing, management, etc。
The smart meters were initially installed to enhance the efficiency of operations such as remote copying, remote switches, etc. With smart meters, each household's electricity needs can be captured in detail and only the necessary amount of power generation and distribution equipment can be activated as required. While smart meters require costs and installation costs, investments in power generation and distribution equipment can be controlled. In addition, the effectiveness of smart meters to control electricity consumption during peak demand periods has become increasingly evident in recent years. Power companies use smart meters to send electricity-related information (consumption and unit prices, etc.) to users, thus reducing electricity consumption according to demand response。
As one of the most based devices in the smart grid, energy-saving technologies of the smart meters themselves are also receiving increasing attention. Because smart meters require the use of dedicated batteries, if they are very power-consuming, the lifetime of the cells will be shortened and insufficient battery power within the meters will affect the measurement and use of power by users. Tens of millions of smart meter replacement batteries are cumbersome and costly for electricity companies and users。
Ansemi semiconductor solutions
To address the above, some targeted solutions for the ansemian semiconductor could be used to address power consumption of smart meters from the outset of design。
Power management and pressure stabilization programmes:
In this regard, the ac-dc semiconductor has a wealth of equipment at its disposal, such as an ac-dc conversion application, a self-electrical high voltage monovoltage pressurizer for low-power offline power, ncp1010-4, a single switch pressurizer for medium-power offline power, ncp1027, a high-voltage door control booster, ncp1050-5; in the dc-dc conversion application, a 500-ma ldo linear pressurizer, ncp5500, a 200-ma output ldo linear pressurizer, ncp4588, a 50/150a wire pressure stabilizer, lm2594/5/6, a pwm controlr, ncp3020/11, and ncp1034; and a 500-m ldo ldp51, a 500ma output ldo voltressor, ncp4588, 50/150a wire pressure stabilizer, 100d46d461 and lpp51. The position of these products in applications is shown in figure 1. These power supply programmes, which are characterized by high energy efficiency, low energy consumption and abundant conservation properties, are well suited for smart meter applications。

Configure and adapt the eeprom program:
Smart spreadsheets address data storage issues and require the use of secure storage devices. Ansemian semiconductor provides a rich memory (e. G. Eeprom, sram) solution for smart meter applications. Eeprom, which is mainly used for the configuration and calibration of smart meters, covers density from 1 kb to 1 mb and has a programming/wielding cycle of up to 1 million times and can work within extended temperatures. These products use different types of interfaces, such as i2c, spi or microwire, where i2c interface products also cover different types of complete array protection, partial array protection and specialty. Figure 2 shows the classification of eeprom products from the ansemian semiconductor. The ansemian semiconductor also launched a user-friendly portable programming tool, easypro, which can be used by users to program eeprom (i2c, spi, microwire) in a series that is very user-friendly and practical。

Recently, several new eeprom devices, including cat24m01, cat24c512 and cat24m01, were launched by the ansemian semiconductor, with data maintained for up to 100 years. The work temperature ranges from -40°c to +125°c in these serial eeproms, manufactured using the 0. 18 micrometre (μm) low-capacity cios process, are undoubtedly the best option to reduce the energy consumption of smart meters。
I/o extension chip and logical converter:
The i2c i/o extension chip of the ansemian semiconductor provides 16 generic i/o functions via i2c bus or smbus. The i/o mouth extension chip can be used for the mmu/dsp generic i/o extension to 8 or 16 gpio via i2c. Simple solutions can be achieved using i/o extensions when additional i/o vents are required to connect acpi power switches, sensors, buttons, leds, fans, etc. The output of the i/o extended chip can directly drive switch controls such as leds, fans, relays, etc.; enter a test input for keyboards, timers/sensors, etc., with interruptions. The use of i2c i/o extension technology for communications between many remote control contacts and hosts could greatly simplify the problem of multiple wiring. Products in this area are pca9655e, pca9535e, pca9535ec, pca9639e and pca9639er. For example, the pca9655e provides an open-spill breakout output, which is activated when any input state is different from its corresponding input port register. Interrupts the output to provide the system master with a changed input status. Up-to-the-spot sets the default value for the register and initializes the unit status machine. Three hardware drawings (ad0, ad1, ad2) are used to configure the i2c bus from its address. Allowing up to 64 devices to share the same i2c bus and smbus, this feature provides great flexibility for applications。
The ansemian semiconductor logical converter is a dual-power voltage logic converter that can connect to ic and printed circuit boards working under different power voltages. This type of device using a stand-alone power source (vl vcc) with 100 pf high-capacity, over-pressure capacity-enabled and i/o lead, non-priority up-to-power sequence and power outage protection can provide flexible pathways for the connection between printed circuit boards and printed circuit boards, as shown in figure 4。
