Features, Applications

The Standalone Tag Reader Circuit (STARC) is an integrated circuit dedicated to the automotive immobilizer applications. It combines on the same chip all the circuitry to interface with a transponder : antenna drivers and demodulator. A low dropout voltage regulator and a physical interface fully compatible with the ISO 9141 norm are also available. The Standalone Tag Reader Circuit is fabricated with the SMARTMOSTM3.5 technology. This process is a double layer metal, 1.4m, 45V technology, combining CMOS and bipolar devices.

Contactless 125kHz tag reader module : - Self synchronous sample & hold demodulator - Amplitude or phase modulation detection - High sensitivity - Fast "read after write" demodulator settling time - Low resistance and high current antenna drivers @ 150mA (typ.) - Bidirectionnal data transmission - Multi tag, multi scheme operation. Low dropout voltage regulator : - Wide input supply voltage range : from 40V - Output current capability 150mA DC with an external power transistor - 5V output voltage with 5% accuracy - Low voltage reset function - Low current consumption in standby mode : 300A (typ.). ISO 9141 transmitter and receiver module : - Input voltage thresholds ratiometric to the supply voltage - Current limitation - Ouput slew rate control - No external protection device required.
