Modern electronic equipment is like a human body system, its working process is a complete information input, output, and processing process. Take the familiar computer as an example. The keyboard, and mouse is the information input device, that complete the interaction between the computer and the outside world. The display is the output device, the internal CPU is the brain, processing a variety of information, and memory hard disk and other equipment is like a memory cell, storing a variety of information data. These are the basic structure of modern electronic devices.
The electronic devices we sell can also be roughly classified in this way, but the content is much richer, and if the following division of the ponderous components is made, the key to the problem is captured.
Starting with the most important
Microcontroller and microprocessor (MCU & CPU)
The microcontroller is the customary domestic call, the general common name is MCU, or microcontroller (Microcontroller). As the name implies, it is the core component of the device, like the brain of the human body, which plays a dominant role over other things. The microprocessor can be seen as a strong processing power MCU, it is different from MCU is that it focuses on computing and MCU focus on control. The more xx microcontroller brands are Intel, Atmel, Microchip, Motorola, Ti, NS, SST of the U.S. Philips, Infenion, ST of Europe, Toshiba, Fujitsu, Mitsubishi, Hitachi of Japan (now these two brands merged into Renesas Semiconductor), Huabang, Holtek, Xinmao of Taiwan, LG, Samsung of South Korea. LG, Samsung.
Our agent brand Taiwan Xinmao (SYNCMOS) microcontroller is the most commonly used 8051 core series of microcontrollers, and the United States ATMEL series of microcontrollers can be interchangeable, and Philips, Huabang's 51 microcontrollers compatible

Memory
There are many types of memory, including SRAM (static memory), DRAM (dynamic memory), EPROM (erasable by UV light), EEPROM (electrically erasable), FLASH (flash memory), FRAM (ferroelectric memory), etc.
The most important indicators of memory are capacity and access time. So many brands of generic models are interchangeable. We have summarized a list of different brands of memory interchangeable, which salespeople can refer to.

Digital Signal Processor (DSP)
A DSP is a digital signal processor. It is also a type of microprocessor, but it has its own distinctive feature of having very strong computing and processing power. This is incomparable to general MCUs. Because of its powerful signal processing capability, it has a very wide range of applications in modern electronic devices. For example, communication, radar, xx control devices, and advanced handheld devices. With the advent of 3G era, the application of DSP becomes more important.
Currently the world's strongest DSP manufacturer is the United States of Texas Instruments (TI), ADI and MOTOROLA is also very strong, with their own special products. Our domestic general application of DSP is TI's TMS320 series, of which TMS3202XX is used in low-end control equipment, TMS3205XX is widely used in the middle xx equipment, and TMS3206XX series is used in xx communication equipment, such as base stations, switches and other products.
