RF Access, Monitoring ICs - ST25R3915-AQFT

The ST25R3915-AQFT is a high performance integrated circuit, specifically designed for use in the field of radio frequency identification (RFID). It combines an RF receiver and transmitter for efficient field communication with a sophisticated state machine for monitoring the frequency of operation.The ST25R3915-AQFT is designed to operate in a wide range of frequencies, from 125 kHz to 915 MHz, and is capable of supporting up to four simultaneous channels. It also has two separate input connector ports that can support up to two different RFID standards, allowing it to be used in multiple RFID applications. It has an integrated external oscillator for stable operation and integrated temperature sensing for accurate temperature measurements.The ST25R3915-AQFT works in conjunction with a reader or a host computer. The reader sends a signal to the IC, initiating an identification or read event. The IC then receives the signal and decodes it, verifying the requested command. The integrated decoupling circuit allows the IC to measure the signal with a high degree of accuracy. The IC then passes the requested information to the host computer, either via serial, parallel, or USB interface.The ST25R3915-AQFT also includes a sophisticated state machine for monitoring the frequency of operation. This state machine monitors the signal frequency of the system and can alert the IC if there is any deviation in the frequency of operation. This is particularly useful in applications where stability is essential for successful communication.The ST25R3915-AQFT also features a set of low pin count, low-power, and low-voltage logic interfaces providing an efficient way to access RFID data. This set of tools allows the device to easily connect to a wide variety of embedded systems and other communication systems and networks. Additionally, the device features an integrated button to activate certain functions and a serial port interface for communication with host devices.The ST25R3915-AQFT supports a variety of protocols to enable interoperability with a variety of RFID systems and can also be used to read a wide variety of tags. The device is compliant with the ISO 14443A, ISO 15693, and ISO 18000-3 standards and also includes support for NFC technology.Finally, the ST25R3915-AQFT also includes a duty cycle control capability. It can be used to control the amount of time that each function is enabled. This is essential in applications where timing is critical or for applications that require dynamic power management, such as battery powered systems.Overall, the ST25R3915-AQFT is a high performance integrated circuit designed to meet the needs of a variety of RFID applications. Its sophisticated state machine and wide range of interfaces allow for efficient communication and enable the device to be used in applications that require dynamic power management. In addition, its low pin count and low power consumption makes it ideal for embedded systems and other communication networks.
