THOR NFC Data Logger
The DELTA Microelectronics THOR is a multiprotocol transponder chip (PICC) that can perform measurements and store results with a configurable time interval (0.1s to 10h). It supports both ISO 14443A (NFC Type 2) and ISO 15693. The protocol type is automatically detected.
Measurements can originate from the on-chip high precision temperature sensor, an external differential analog signal or from the SPI master interface. The logging capacity is up to 24 KB (about 8,000 samples of time-stamped data). The data transfer rate is up to 848 kb/s at short distances. With a credit card size antenna, operation 8 cm from reader is possible (26.48 kb/s).
For autonomous (active) logging, the device can be mounted with a 2.7 – 5.5V battery. When no measurement is performed, standby current consumption is below 1 μA. When an RF field is applied, the internal power supply switches to power extracted from the RF field. In this way, data from the memory can be accessed even with an expired battery. The chip can also supply an auxiliary slave, e.g. a sensor with SPI interface, designed for 2.7 – 5.5V range. Typical output from the chip is 3.1V.
The embedded EEPROM memory size is 32 K bytes. Apart from measurement results and default drivers, it can also hold custom SW applications. Tamper detection can also be supported. DES hardware encryption is available for data privacy.
Environment monitoring of objects/parcels using the built-in temperature sensor and external SPI-controlled sensors (e.g. humidity, pressure, tilt, voltage, light, proximity, vibration, etc.).
The manufacturer sells these devices in lots of 1,000 (to keep the unit cost low). Therefore need as many customers as possible to build the volume.
Packaged ASICs in a 32-pin QFN package.
Campaign active, ends when minimum unit count reached
GroupGets will handle the shipment of orders for this product.
The THOR evaluation board is essential to developing the end products the THOR ASIC is going to be used in. Included with the development kit are Linux and Android software development kernals.
