128 bit Read Only Low Frequency Contactless Identification Device-EM4200 key card is a CMOS integrated |
|
|
|
| circuit intended for use in electronic Read Only RF transponders. It is designed to replace seamlessly the EM |
|
| Microelectronic-Marin Read Only ICs EM4100/4102 and EM4005/4105. |
|
| EM4200 Key Card |
|
| 1. Chips: EM4200 |
|
| 2. Dimension: CR80 or as customer's requirement |
|
| 3. Frequency: 125KHz |
|
| 4. Standard ISO11785 |
|
| 5. Material: PVC or ABS |
|
| 6. Data saved time: 10 years |
|
| 7. Options: Signature panel, LOCO/HICO Magnetic Stripe, embossing letter and number, barcode, sequential |
|
| numbering, Gold/Silver card, frosted card. |
|
| 8. Application: EM4200 Key Card is widely used in Parking lot system and hotel door locks, for its long inductive |
|
| distance(70-2000px), ISO Thin EM Card is widely used in Access Control System, Time and attendance, parking |
|
| lot and consuming system. |
|
| The circuit is powered by an external coil placed in an electromagnetic field and gets its master clock from the |
|
| same field. By turning on and off the modulation current, the chip sends back the unique code contained in a |
|
| factory pre-programmed laser ROM. |
|
| The 128 bit unique code is stored in laser programmed ROM. Several options are available to use 64, 96 or |
|
| 128 bits of ROM. |
|
| The IC offers also different resonant capacitor versions, selectable by mask option (0pF, 75pF and 250pF) |
|
| providing the same reading performances to ensure seamless replacement. |
