What is the maximum capacity of the TF card?

It depends on what you're up for.

I now use a 16g mobile phone, and I feel okay.

Theoretically, there is 32G, and it is estimated that general electronic products cannot be supported, because the power does not meet the requirements of the configuration.

Micro SD Card, formerly known as Trans-Flash Card (TF Card), was officially renamed Micro SD Card in 2004 and was invented by SanDisk. Before the introduction of the micro SD, mobile phone manufacturers used embedded memory, and although these modules were easy to install, they were plagued by the fact that they could not meet the needs of the actual trend - the capacity was limited, and there was no room for upgrades. The micro SD imitates the application mode of the SIM card, that is, the same card can be used in different models of mobile **, so that mobile ** manufacturers no longer have to worry about the development and design of the plug-in card.

A micro SD card is enough to be called a removable storage IC.

A micro SD card is a tiny flash memory card with a format derived from the creation of SanDisk, originally called T-Flash, and later renamed Trans Flash; The reason for the renaming of the Micro SD is that it was adopted by the SD Association (SDA). Other memory cards adopted by SDA include Mini SD and SD cards. It is mainly used in mobile **, but due to its small size and increasing storage capacity, it has been used in GPS devices, portable **** devices and some flash memory disks.

At 15mm x 11mm x 1mm, it is about the size of a fingernail, making it the smallest memory card in existence. It can also be used in SD card slots via SD riser cards. MicroSD cards are available in 128MB, 256MB, 512MB, 1G, 2G, 4G, 8G, 16G, 32G and 64G capacities (During MWC 2014, SanDisk broke the tradition of memory cards with a maximum capacity of 64GB and officially released a Micro SD XC memory card with a capacity of up to 128GB.

128g

At present, the main reading and writing of TF cards are Class 4, Class 6, Class 10, etc.

The specific speed is as follows:

Class 0: includes cases below class 2 and without speed class;

Class 2: It can meet the needs of ordinary MPEG4 MPEG2 movies, SDTV, and digital camcorder shooting, with a speed of 2MB s;

Class 6: Meet the requirements of continuous shooting of DSLR cameras and professional equipment, with a speed of 6MB s;

class10: meets the storage requirements of higher speed requirements, with a speed of 10 MB s.

600x: 99MB s.

UHS-i: indicates that the UHS (Ultra High Speed) interface is supported, and its bandwidth reaches 104 MB s.

TF card size 15mm x 11mm x1mm.

Micro SD Card, formerly known as Trans-Flash Card (TF Card), was officially renamed Micro SD Card in 2004.

MicroSD cards are available in 128MB, 256MB, 512MB, 1G, 2G, 4G, 8G, 16G, 32G, 64G, and 128G capacities (During MWC 2014, SanDisk broke the tradition of memory cards with a maximum capacity of 64GB and officially released a Micro SD XC memory card with a capacity of up to 128GB.

At the heart of a memory card is a tiny unit of memory circuitry etched into a silicon wafer. 1 memory circuit unit stores 1 bit (1 or 0), 8 counts as 1 byte, and 1g = 1024 to the third power of bytes. Although a memory circuit unit is small, it still takes up space.

Therefore, the capacity of the TF card is related to the size of the TF card, the volume is there, if the process is not changed (such as using a smaller nano process), the principle is not changed, and the capacity is too large, the TF card will not be able to be made. And not only the size limit, if the memory cells are too dense, the arrangement of the circuit will also become complicated, and they will interfere with each other.

Then, the memory circuit units in the memory chip can be thought of as being made piece by piece. Make more and less pieces, and the capacity will naturally be different. Assuming that the capacity of a piece is 1m (actually very small), then the 1G card is generally 1100 pieces, and then detect, the bad shield, the good retention, enough 1024 (actually 1000 on the line) The good one is 1G.

It's ready to go public.

If there is a 2G card, but there are many bad blocks, only enough for 1G, it will also be marked as 1G after shielding the bad blocks**.

The battery, the computer's CPU, the chips on the circuits actually do this. The production is an approximate quantity, and then according to the factory inspection results, and then marked with different specifications**.

TF card size 15mm x 11mm x1mm.

Micro SD Card, formerly known as Trans-Flash Card (TF Card), was officially renamed Micro SD Card in 2004, invented by SanDisk (SanDisk), mainly used for mobile **.

Currently, MicroSD cards are available in 128MB, 256MB, 512MB, 1G, 2G, 4G, 8G, 16G, 32G, 64G, and 128G capacities (During MWC 2014, SanDisk broke the tradition of memory cards with a maximum capacity of 64GB and officially released a Micro SD XC memory card with a capacity of up to 128GB).

Measuring 15mm x 11mm x1mm, it is almost the size of a finger and is the tiniest memory card available. It can also be used in SD card slots via SD riser cards.

10mmx15mm is mostly the same, there are also non-standard water.
