Introduction to the latest MTK platform Chip

The MTK platform is a widely used embedded operating system of the basic nucleus OS. Mobile phones on the same MTK platform have different features, different speeds, and different software. All these are due to the chipset. We can use the WM system for comparison. WM is equivalent to MTK. We should always know the kernel version of wmrom, such as 23001,23004 and 23009. Therefore, the chipset 6227,6229 in MTK is, 6235 is similar to the kernel version in WM (for example, it is actually different ).

Different mobile phones use different MTK chips, resulting in different mobile phone functions. So how can I know the version number of my mobile phone? Enter the * #66 * # character (different models) on your keyboard. If you use a mobile phone on the MTK platform, the mobile phone engineering interface is displayed. At this time, in the "version", that is, "version information" column, we flip down and click "BB chip" to display the chip model of the motherboard.

MTK has three chipset types:

The first is the power chip. Currently, MTK has two power chips: mt6305 and mt6318.
The second type is the RF chip. Currently, all RF chips of MTK models use mt6129 and mt6139 chips to receive and transmit signals.
The third is the CPU chip, also known as the master chip. What we usually call MTK chip is the CPU chip.

Mt6205, mt6217, mt6218, mt6219, mt6225, mt6226, mt6227, and mt6228 are all baseband chips. Therefore, the chips all adopt the ARM7 core.

Mtk cpu, such as 6205, 6217, 6218, 6219 and other flash data is not encrypted, the later CPU such as 6223, 6225, 6226ba, 6228, 6230 and so on are encrypted flash data. Here, data encryption means that mobile phones of the same model are incompatible with each other. These chipsets are also rough at the beginning, and gradually mature or even outstanding:

Mt6205 is the earliest Chip Solution for MTK. It only supports the basic functions of GSM and does not support functions such as GPRS, WAP, and MP3. At this time, MTK is just a mobile phone, and there is no third-party extension.

Mt6218 has developed slowly. Based on mt6205, some basic entertainment functions such as GPRS, WAP, and MP3 are added.

Mt6217 is a low-cost mt6218 solution, which is completely compatible with mt6128 pins, but it is different from the software. mt6217 also supports 16 bit data.

Mt6219 adds the 1.3 million camera processing chip with built-in ait on the basis of mt6218, adds the MP4 function, and supports 8-bit data.

Mt6225 is a music mobile phone solution, VGA Camera Mobile Phone, GPRS, excellent power consumption.

Chips from mt6226 and later support the webcam function. That is to say, your mobile phone can be used for QQ videos, or you can connect your mobile phone to your computer as a computer camera.

Mt6226 is a low-cost solution product of mt6219. It has a built-in 0.3 million pixel camera processing chip and supports GPRS, WAP, MP3, and MP4. Its internal configuration is optimized and improved compared with mt6219, for example, you can configure Bluetooth and use the bc03 module usd3 of the cheap chip CSR to support data transmission.

Mt6226m is a high configuration design of mt6226. It has a built-in 1.3 million camera processing chip, extended music standard, and supports Avi and 3GP.

The mt6227 and mt6226 functions are basically the same, but the built-in 2 million camera processing chip is used.

Mt6228 than mt6227 added TV-OUT function, built-in 3 million camera processing chip, support GPRS, WAP, MP3, MP4 and so on.

Mt6229 is an upgraded version of mt6228. Edge, sliding screen, and other functions are added on the basis of 6228. Other functions are the same.

Mt6230 has built-in 1.3 million camera processing chip.

Mt6235 has built-in 2 million camera processing chip. Currently, there are many 6235 mobile phones, and many of the latest MTK models are 6235 chips. For example, all MTK mobile phones of sharp, Tianyu v760, Lenovo I60/i60s/x1/x1m /, osson's T9 and Haier's H2. 6235 supports a maximum resolution of 240*400, and a maximum resolution of 3.2 million pixels.

Mt6238 built-in 3 million camera processing chip, supporting mobile TV

Mt6239 is the latest platform for MTK. It has a built-in processing chip of up to 5 million cameras. The operating interface can be changed to the topic, and because of its high CPU frequency, therefore, the system response speed of mobile phone models using the mt6239 platform is faster and faster than that of other chips.

The mtk6239 platform also supports richer multimedia features. For example, 5 million pixels, 640x480 resolution, 30 frames/second, and 30 frames/second. video Playback in 264 format: supports popular cmmb mobile phones and G-sensor gravity? * ***** The zookeeper Java application. These rich features are beyond the reach of previous MTK platforms, but currently there are only a few models on the market, such as osson M55, using the mt6239 platform design.
