STMicroelectronics Push new embedded RFID chip applicable scope once again expansion

RFID is a market prospect in areas such as retail, security inspections. Under the promotion of industry companies, the technology R & D work is steadily, and it is a recently launched an embedded RFID chip in recently, further expanding the application. Radio frequency identification, RFID technology, also known as wireless RF identification, is a communication technology that recognizes a specific target and reads and write related data over a radio signal, without having to identify a system and a particular target to establish mechanical or optical contact. Commonly used low-frequency (125K ~ 134.2K), high frequency (13.56MHz), ultra-high frequency, microwave and other technologies. The RFID reader also is also divided into mobile and fixed. Many industries began to use RF identification technology. Attaching the label in a car that is producing, the plant is convenient to track the progress of this car on the production line. The warehouse can track the pharmaceuticals. The RF label can also be attached to livestock and pets to facilitate positive recognition of livestock and pets (positive recognition means to prevent several livestocks from using the same identity). The identification card of RF identification can enable employees to enter the locked building part, and the RF transponder on the car can also be used to levy the fee section and the parking lot. Currently, the STMicroelectronics has introduced a new embedded RFID chip that makes the near-field communication (NFC) feature easier to join any type of electronic device, from speakers to printers, cookware, washing machine, even electricity, gas and water meter . The M24SR series NFCRFID chip contains three key elements: non-volatile memory (NVM), even if the power supply can also retain its storage data; wireless RF interface communicating with other wireless devices; a wired interface (I2C of industry standard) Host device controller communication. In the M24SR series, NVM is implemented using an erased programmable read-only memory (EEPROM), with a large capacity of 2, 4, 16 or 64. Its wireless interface is compatible with the ISO14443A protocol, up to 106 bits per second. The I2C interface is up to 1MHz in the data transfer between smartphones and target devices. According to the above-described semiconductor, the EEPROM memory allows NFC operation to support NFC data exchange format (NDEF), and use the latest EEPROM technology, data retaining 200 years, one million rubbing, write operation, 128-bit password protection, to achieve the largest Safety. A M24SR series is the most typical example in practical applications, which is a favorable Bluetooth mobile phone and an audio device. It does not have to open the settings of the phone, start the Bluetooth connection (select the audio device code, sometimes enter a password); Now the user can simply shake a smartphone and achieve pairing the NFC audio equipment.
