NXP immobilizer system solutions Reduced system cost for high-security immobilizer designs NXPs leading portfolio for immobilizer system includes a full range of security options for the transponder side, perfectly complemented by advanced basestation solutions. PCF7938 features ABIC2 features Immobilizer transponder with 96-bit secret key Fully integrated single-chip basestation (PJF7992, PJF7993) 448 Byte of EEPROM with versatile access configuration High-performance adaptive sampling time AM/PM options demodulator Integrated voltage regulator with wide supply-voltage range Benefits (5.6 to 27 V) Easy migration from PCF7936/37 Antenna driver with wave shaping for improved spectral purity High security Serial interface featuring SPI and single-wire operation Fast authentication time Integrated LIN 2.0/SAE J2602 transceiver (compatible with LIN 1.3) The NXP PCF7938, an immobilizer transponder for advanced LIN 2.0-tolerant protocol optimized for reliable transponder security, builds on the success of the field-proven PCF7936/37 data handling and PCF7939 (AES-128-Bit). It offers advanced security with a Buffered communication via single wire interface possible for 96-bit secret key, enabling an easy migration path for customers easier system design using the PCF7936. It offers more memory to store user data, W atchdog and Power On Reset functions with versatile access configuration options. As with other NXP T emperature sensor to protect the device against overheating immobilizer transponders, NXP offers keyless entry/go and 20-pin Heatsink TSSOP (HTSSOP) package remote keyless entry solutions fully compatible to PCF7938. Benefits Reduced system cost through high level of integration Facilitated system design and shorter time to market Low power consumptionThe NXP ABIC2 (PJF7992) is a next-generation immobilizer microcontroller at the basestation obsolete by integrating basestation with a high level of integration. It provides read anda single-wire protocol that is LIN tolerant and does not write access to an identification transponder. It offers a number influence or affect further LIN slaves in the same LIN network. of enhancements over the ABIC (PCF7991), including an An external microcontroller can be added to implement another on-chip voltage regulator and single-wire communication using protocol layer, such as LIN 2.0. For this kind of application the the integrated LIN Transceiver ABIC2 derivative PJF7993 is offered. Bidirectional communication with the device uses a serial The ABIC2 IC is optimized for easy application, featuring a high interface that operates in SPI or single-wire fashion, according level of integration in a small HTSSOP20 package and requiring to the application needs. ABIC2 makes an external very few external components.
