Memories

ST offers a wide range of non-volatile memories. The serial EEPROM family ranges from 1 Kbit to 2 Mbits and offers different serial interfaces: I²C, SPI, Microwire. The wide range of products are also automotive compliant and very thin packages are available for applications where space is critical. 

The innovative family of Dual Interface EEPROMs offers new features and capabilities. The EEPROM memory bank provides read and write access by either a standard I²C interface or by an 
ISO 15693 RF interface. This new type of wireless memory enables on-board energy savings and provides easy and convenient remote access to electronic product parameters. 

ST offers a wide range of RFID reader ICs and tag ICs for contactless short-range and long-range applications. The products comply with the ISO 14443 and ISO 15693 RFID standards based on the 13.56 MHz carrier frequency. They can also communicate with ISO 15693-capable NFC devices.

NVRAMs are battery-backed SRAMs that range from 16 Kbits to 
32 Mbits. They are available in two types of packaging, either a fully-integrated solution in a DIP package that includes a battery, or a surface-mount SOIC package that allows for a SNAPHAT replaceable battery. Timekeeping and clock functions are also available.
