General Description

The SL900A is an EPC tag IC operating in semi-passive mode (battery-assisted passive) 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 (RTC).

This product suits for the following applications:

  • Supply and cold chain
  • Tracking condition and history of constructions
  • Tire pressure monitoring systems (TPMS)
  • Contactless metering
