Industrial flash memory card: CF card, SD card, TF card

  There are many types of industrial flash memory cards. Common ones include CF card, SD card, MMC card, memory stick, SM card, xD card, TF card, etc. Among them, CF card has a long history. Due to its long time to establish standards, , good compatibility, large capacity, low price and other reasons, it has been widely used. It is one of the most versatile memory cards.
SD card

  CF card means "standard flash memory card". As an advanced mobile digital storage product, the advantages of CF card were obvious at that time. It had the advantages of high speed, large capacity, small size, light weight, low power consumption, etc., and it easily gained unanimous recognition.
  The CF card uses flash as the storage medium, which can save data without power supply, and consumes very little power when working. It operates at a voltage of 3.3V or 5V, and its power consumption is only equivalent to traditional storage devices such as tapes and hard disks. 3% or less, suitable for use in mobile devices; CF card consists of two basic parts: control chip and flash memory module, flash memory is used to store information, control chip is used to connect to the host and control data in the flash memory Transmissions in modules.
  Industrial-grade CF flash memory card has larger capacity, faster speed and stronger stability.
  Industrial-grade CF flash memory cards are used in small-sized devices with PATA interface. They are suitable for various industrial fields and any harsh environment. Industrial-grade CF cards are one of the most reliable and very durable flash storage products on the market today. The product adopts the highest Quality NAND for applications requiring data integrity and 100% uptime. It is small in size and sturdy in structure, and is very suitable for embedded flash storage needs.
SD card

  SD card is a secure digital card, which is a new generation memory device based on semiconductor flash memory. It is developed on the basis of MMC and adds two main features: SD card emphasizes the security of data and can set the stored usage permissions to prevent data from being copied by others.
  The industrial-grade SD card has a small size and a small number of gold fingers, making it suitable for use as small embedded storage. If the application has special requirements for the temperature range, you can choose a wide-temperature product that supports -40C to +85C.
  TF card
  T-Flash is abbreviated as TF or Micro SD card. It is the kind of small memory card used in mobile phones. Laptops usually have an SD card slot, but there is no TF card slot, so I want the laptop to read TF directly. card, you also need an adapter from tf card to sd card
  Industrial-grade TF card is light in weight and can withstand relatively high vibrations. If the application has special requirements for the temperature range, you can choose a wide-temperature product that supports -40 to +85C.
