The EM4100 Chip is the first in the EM Series. It is a low-frequency, contactless, and read-only identification system/device with 65 bits. The EM4100 Chip utilizes an improved chip packaged model that is a comprehensive solution and model for contactless-card applications. Similarly, the EM4100 chip model enables special printing services as well as specially designed cards that are useful in the application environment.

 

To summarize, the EM4100 Chip is useful in identity identification systems, attendance systems, property identification systems, and access control systems. The EM4200 Chip is an improved version of the EM4100 Chip.

 

EM4200 

The EM4200 Chip is a 128-bit read-only low-frequency contactless ID device. It is a Complementary metal-oxide-semiconductor (CMOS) integrated circuit that can be used in electronic read-only radio frequency transponders.

 

It is designed to be a viable alternative to the EM Microelectronic Marin EM4005/4105 and EM4100/4102 Read-only Integrated Circuits. When compared to the EM4100/4102 or EM4005/4105 chips, the EM4200 Chip has a wider reading range and higher resonant capacitors on its coil terminals.

 

The 128-bit special code of the EM4200 Chip is safely reserved in a laser-operated ROM. There are several ROM options available, including 64-bit, 96-bit, and 128-bit. Furthermore, its circuit is powered by an extrinsic coil in an electromagnetic field, which also serves as the master clock.

 

When the modulation current is switched on and off, the Chip transmits the special code stored in an automated laser ROM.

 

It may surprise you to learn that the EM4200 Chip is useful in animal identification in accordance with ISO11785 standards. It is also used in anti-counterfeiting and access control systems. The EM4200 Chip is also used in waste management and industrial transponders.

 

Chip EM4205/4305

The EM4205/4305 is a contactless low-frequency multi-purpose ID device with 512 bits. It is a Complementary metal-oxide-semiconductor (CMOS) integrated circuit that can be used in electronic read-only radio frequency transponders.

 

It is effective for low-cost solutions, such as animal tagging applications. The EM4469/4569 family and the integrated circuit-communication protocol are both compatible. Despite some similarities, EM4205 and EM4305 have a significant difference that distinguishes them.

 

The EM4305 now has large bumped pads to accommodate the two coil inputs. These large bumped pads are used for direct antenna connections that do not require a module. The EM4305 also has a 330pF resonant capacitor. The integrated circuit is powered by a 125 kHz magnetic field that runs through an external coil and combines with the integrated capacitor to form a resonant circuit.

 

Following that, the integrated circuit transmits data to the coil from the internal EEPROM. This is accomplished by using a large modulation index to toggle the resistive load on and off. When the 125 kHz magnetic field is modulated with 100 percent AM, the EEPROM data updates and system commands can be triggered.

 

The data and bi-phase encodings are powered by the EM4205/4305 group (Manchester). The operating modules are stored in the EEPROM configuration. And the EEPROM words are protected against write attacks by configuring the protection bits.

 

The integrated circuit has a 32-bit unique identification number. In terms of application, the EM4205/4305 is suitable for access control and animal identification in accordance with ISO FDX-B standards. It is also useful for waste management systems.

 

EM4095

The EM4095, formerly known as the P4095 Chip, has a frequency range of 125 kHz-134 kHz. It is also equipped with a read/write front-end analog to support an RFID base station. The EM4095 is a complementary metal-oxide-semiconductor (CMOS) transceiver circuit that enables RFID base-station for a variety of functions.

 

The EM4095 activates the antenna driving using the carrier frequency and allows microprocessor communication via a simple interface. EM4095 chips are easily found in car immobilizers, low-cost readers, and hand-held readers.

 

 EM4097

The read/write analog front-end integrated circuit is included with the EM4097 Chip, formerly known as the P4097. With a frequency range of 125- 134.2 kHz, it has a serial micro-coulombs interface that is useful in RFID base-station applications. Furthermore, the EM4097 Chip is notable for its low power consumption, making it more cost effective than many RFID chips on the market.

 

Furthermore, the EM4097 Chip incorporates a complementary metal-oxide-semiconductor (CMOS) transceiver circuit that can be used by RFID base-stations to perform a variety of functions.

 

To begin, the EM4097 Chip impacts the antenna driving with carrier-frequency to provide energy to the transponder. The EM4097 Chip also allows the writable transponder to transfer data using field amplitude modulation.

 

Data transfer from the transponder is accomplished through phase or amplitude demodulation. Finally, it includes a micro-coulombs interface for communicating with the microprocessor.

 

The EM4097 Chip can be found in Animal ID readers as well as hand-held low-frequency readers.

 

 EM4450

The EM4450 Chip is one of the most recent EM series chips available. It is a 1-kbit low-frequency contactless ID device. It is a Complementary metal-oxide-semiconductor (CMOS) incorporated circuit useful for electrical read/write radio frequency transponders, as are the majority of the chips mentioned above.

 

It is important to note that the EM4450 Chip includes a 1 Kbit EEPROM that can be remodeled by any user. This remodeling or configuration enables a read-protected area, a write-inhibited area, and a read-area output with continuous switched-on power.

 

The EM4450 Chip's memory can be secured with a 32-bit password for all read and write protected functions. The password can be easily and quickly updated; however, it cannot be read. The serial number code is fixed, and it is laser-programmed along with the device identification. As a result, each Chip is distinct and one-of-a-kind.

 

The EM4450 Chip also sends data to the transceiver via amplitude modulation of the electromagnetic field. It also receives commands and data. The EEPROM can be programmed with simple commands to update the password, read a unique memory region, and reset the logic.

 

The only important external constituent in this case is the tuned circuit's coil. At the same time, the Chip incorporates the rest functions.

 

The EM4450 Chip is useful in ticketing, prepayment, and manufacturing automation applications. It is especially useful when setting up industrial automation with a portable database.

 

What Is the Distinction Between Them?

It is critical to note that before selecting an EM chip, you must be certain of what you need it for. Each EM chip mentioned in this piece has unique characteristics that set it apart from the others. You will also notice that each EM chip has variable characteristics such as bit size, memory capacity, and a slew of others.

 

As a result, depending on what you require the EM chip for, you must be certain of your specific requirements before selecting one.

 

Furthermore, almost all EM chips require low power to operate. This means you shouldn't be concerned about modifying the power capacity of any EM chip you buy. If you are unsure which one to choose, it is critical that you consult with a professional before making a decision.

 

Each EM chip is unique in its own way, and even if they have similar features, it is best to be certain before purchasing any.
