IC REMOTE KEYLESS ENTRY PCF7991AT for car key

We are the IDH of NXP , here the details of the part :

Description:

1.Highly integrated and powerful advanced basestaion IC,ABIC,suited for vehicle immobilisation applications.
2. Incorporates all necessary functions to facilitate reading and writing of transponders.
3.The ABIC,PCF1991employs a unique AM/PM demodulation techique .
4.The carrier frequency can be derived from an on-chiposcillator or an external clock source.
5.The device enables system diagnostic functions byantenna fail detection features.

Features:

1.Extended system operating range due to powerfulAM/PM demodulation technique                                         2. Ideally suited for "Intelligent Antenna" and "ActiveAntenna" architectures                                      

3.High antenna drive capabilities, CW: 200mAp                                            

4.Low antenna driver output resistance, 3.5 om                                 

5.Excellent receiver sensitivity, 2mVpp      

6.Large receiver dynamic range    

7.Programmable clock divider, modulator, receivergain and filter characteristics                                      

8. Fast "read after write" receiver settlingcharacteristics                                

9. On-chip receive EMI filter            

10. Antenna failure mode detection  

11.Few external components                      

12. Operating supply voltage: 4.5 to 5.5 V                                              

13. Power down mode: 7µA @ 5.5 V    

14.14-pin SO package

Applications:

1.vehicle immobilisation applications        

2.can be used in combination withcommonly available transponder that employ ASKmodulation                         3.on-chiposcillator an external clock source.                                                

4.transponder
