The 2262 and T19 are two different RFID chips, mainly different in application and mode of operation. The specific differences are as follows:
< br >
1. Application: 2262 is mainly used in remote control, security and smart home and other fields; T19 is mainly used in the field of vehicle gate and access control system.
< br >
2. Operating frequency: The 2262 operates at 315 MHz or 433 MHz, while the T19 operates at 920 MHz.
< br >
3. Working mode: 2262 is a one-way identification chip, that is, it can only recognize the RF signal sent by the transmitter, without feedback function; T19 supports two-way communication, and can achieve multiple functions such as reading and writing, encryption, and verification.
< br >
4. Security: T19 adopts advanced encryption algorithm to ensure the security and privacy of identification data; The 2262 is simpler and less secure.

It should be noted that different chips are suitable for different scenarios and applications, and need to be selected according to actual needs.
The difference between gate chip 2262 and t19 is that their digital composition structure and numerical size are not the same, and the parity is also different. 2262 is made up of four even numbers, which is a four-digit positive even number, and 1527 is made up of three different odd numbers and one even number, which has an odd number. And from the point of view of the value, the value of 2262 is greater than the value of 1527.
Is significant. First of all, the 2262 is an excellent radio frequency receiver chip, and the t19 is a low-power Bluetooth chip. Second, the 2262 can receive 315\/433.92MHz RF signals, which is very suitable for wireless remote controls in the field of security, while the t19 is suitable for low-power Bluetooth iot devices. In addition, 2262 is a traditional wireless remote control solution, and t19 is a new generation of iot device communication solution, more flexible and more convenient. Therefore, although they are both chips, the application areas and performance characteristics are very different.
There are obvious differences between the 2262 and T19 gate chips. First, the 2262 is a single chip, while the T19 is a family of ARM processor-based chips with stronger core processing performance. Second, in use, 2262 is mainly used to decode RF433 wireless remote control signals, and T19 in addition to decoding remote control signals, but also to achieve a variety of complex control logic, such as intelligent interconnection and parking billing.
With the continuous development of intelligent gate, the functions of T19 chip will be more diversified, and it is expected to become the mainstream chip in the future intelligent parking field. At the same time, although the 2262 chip is narrow in use, it still has its advantages in some simple application scenarios because of its simple use and low price.
2262 is PT-2262 coding chip, address code (or transmit\/receive between the system password) can be self-set, the number of adjustable address code is small, the receiver decoding pair PT-2272.
Gate t19 chip generally transmit power less than 10mW, coverage less than 100m or does not exceed the scope of the unit, can be free to use without the approval of the \"radio Management Committee\".
