SL900A

EPC Class 3 Sensory Tag Chip

The SL900A is an EPC Class 3 (cool-Log™) sensory tag chip enabling affordable RFID automatic data logging applications with sensor functions. This sophisticated chip makes it practical and affordable to automatically track, monitor, time-stamp and record information about any goods in any supply chain or cold chain transport. Furthermore, the SL900A enables vast new applications in areas such as medical, healthcare and environmental supervision.
Complete development kits including an R902DRM reader board and a SL900A smart data logger board are available. The kits come with demo application and GUI software with source codes.

Description:

The SL900A works in semi-passive mode (battery-assisted passiv) as well as in fully passive mode. The chip is ideal for applications using thin and flexible batteries (1.5V or 3V) for autonomous logging from the integrated temperature sensor or external sensors with time-stamp from on-chip real-time clock. The SPI/IO port allows connection of external circuits.
