MC33690 Standalone Tag
Reader Circuit
The standalone tag reader circuit (STARC) is an integrated
circuit dedicated to the automotive immobilizer applications.
It combines the antenna drivers and demodulator necessary to
interface with a transponder.
A low dropout voltage regulator and a physical interface fully
compatible with the ISO 9141 norm are also available.
The STARC is fabricated with the SMARTMOSTM3.5
technology. This process is a double layer metal 1.4µm
45V technology, combining CMOS and bipolar devices.
• Contactless 125 kHz tag reader module:
• Low dropout voltage regulator:
• ISO 9141 transmitter and receiver module:
