I2C serial EEPROM application system’s toughness design
Tuesday, November 11th, 2008 at 22:49 | No commentsCategories: StorageShort Content: Introduction In the embedded control system, usually must use the nonvolatile storage. Regardless of being time the power failure the maintenance needs to preserve establishment, saves the important record, the reliable nonvolatile storage is one kind of ideal choice. Exterior the non-volatility saves uses the serial storage to realize frequently, the I2C connection product is the most commonly used one type. However, this product and other EEPROM memory are the same, when use also has some conditions to meet latent ... -
In high speed data gathering system’s memory and transmission control logic design
Sunday, November 9th, 2008 at 15:49 | No commentsCategories: StorageTags: memory, TransmissionShort Content: Along with information science's swift development, the data acquisition and the storage technology widely apply in domains and so on radar, correspondence, telemetering remote sensing. In the high speed data gathering system, transforms after ADC the data needs to save in the memory, carries on corresponding processing again, guaranteed that fast accurate data transmission processing realizes a high speed data gathering key. Is very high as a result of the high speed ADC transfer ratio, but large capacity RAM the ... -
Green environmental protection memory
Saturday, November 8th, 2008 at 09:49 | No commentsCategories: StorageShort Content: In view of the fact that the environment question receives people's widespread attention more and more, the global electron profession started to devote in promotes the low energy consumption in the market the product. The white electrical appliances' energy consumption rank is the sales data which the people pay attention, the reference energy consumption height is helpful to the control electrical bill; Now, not only we realize the energy consumption to be low may reduce the electrical bill, moreover is ... -
