The EM chip is a contactless radio frequency identification chip with a read/write function. This EM chip is manufactured by EM Microelectronics in Switzerland with a frequency range of 100-150 kHz. The EM chip is your best choice if you need a contactless RFID chip with minimal power consumption.

The EM chip can transmit multiple data standards efficiently, and with its low power consumption, it can encrypt data smoothly. This RF chip also complies with ISO 11784/11785 and ISO FDX/B (animal identification) standards.

RF chips are also useful in tracking systems, animal identification, and many other applications.

In general, the EM chip has 32-bit password protection, a 10-bit user code, and a 32-bit unique ID code. Furthermore, the EM card has an EEPROM memory of 512 bits and 16 distinct sectors, each with 32 bits.

By setting the lock bits, the EEPROM data block can become read-only. EM4469 provides a wide range of data encodings and rates with low power consumption. With its internally integrated resonant capacitors and mask selectable resonant capacitors, the EM4469 is fully operational. As a result, external capacitors are not required.

In addition, the EM series RFID chip features an internal chip rectifier and voltage limiter that work between -40 degrees Celsius and 85 degrees Celsius.

Chip EM4100

EM4100 is the first chip in the EM Series. It is a low-frequency, contactless, and read-only identification system/device with 65 bits. A comprehensive solution and model for contactless-card applications is provided by the EM4100 Chip.Additionally, the EM4100 chip model provides special printing services and uniquely crafted cards for application-specific needs.

In summary, the EM4100 Chip can be used for identity identification, attendance systems, property identification, and access control. An upgraded version of the EM4100 chip is the EM4200.

Chip EM4200

The EM4200 Chip is a low-frequency, 128-bit contactless ID device. In radio frequency transponders, it is used as a complementary metal-oxide-semiconductor (CMOS) incorporated circuit.

The EM Microelectronic Marin Read-only Integrated Circuits EM4005/4105 and EM4100/4102 are structured to be a worthy alternative. Compared to the EM4100/4102 or the EM4005/4105, the EM4200 Chip has a wider reading range and higher resonant capacitors.

A laser-operated ROM stores the EM4200 Chip's 128-bit special code. ROM options include 64-bits, 96-bits, and 128-bits. Furthermore, its circuit is powered by an extrinsic coil in an electromagnetic field, which also powers its master clock.

In an automated laser ROM, the Chip transmits the special code when the modulation current is switched on and off.

You would be amazed to know that the EM4200 Chip can be used for animal identification according to ISO11785. It is also used in anti-counterfeiting systems and access control systems. EM4200 Chips are also used in waste management and industrial transponders.

A chip with the EM4205/4305 specification

An EM4205/4305 is a 512-bit contactless low-frequency multipurpose ID device. This is a Complementary metal-oxide-semiconductor (CMOS) circuit used in electronic read-only radio frequency transponders.

Applications for animal tagging, for example, are efficient for solutions that don't cost a lot. The EM4469/4569 family is compatible with the integrated circuit-communication protocol. Although EM4205 and EM4305 share some similarities, they have a major difference.

As a result, the EM4305 is equipped with large bumped pads that are suitable for containing the two coil inputs. The big bumped pads are used for direct antenna connection without a module. In addition, the EM4305 provides a 330pF resonant capacitor. Resonant circuits are produced by combining an external coil with an integrated capacitor to produce 125 kHz running magnetic fields.

The integrated circuit transmits the data to the coil from the internal EEPROM. A big modulation index is used to toggle the resistive load on and off. Data updates and system commands can be triggered when the 125 kHz magnetic field undergoes 100% AM modulation.

Data and bi-phase encodings (Manchester) are powered by the EM4205/4305 group. Its operating modules are stored in the EEPROM configuration. Write protection is provided by configuring the protection bits on EEPROM words.

A 32-bit unique identification number is included on the integrated circuit. According to ISO FDX-B, the EM4205/4305 is useful for access control and animal identification. Waste management systems can also benefit from it.

Chip EM4095

It has a frequency range of 125 kHz-134 kHz, and was previously known as the P4095 Chip. An RFID base station can be enabled by a read/write front-end analog. An RFID base-station can be configured with the EM4095, a complementary metal-oxide-semiconductor (CMOS) integrated transceiver circuit.

In the EM4095, antenna driving is activated by a carrier frequency, and microprocessor communication is enabled by a simple interface. The EM4095 chip can easily be found in car immobilizers, low-cost readers, and handheld readers.

Chip EM4097

An analog front-end integrated circuit is included in the EM4097 Chip, formerly known as the P4097. With a frequency range of 125- 134.2 kHz, it is suitable for RFID base-station applications. Additionally, the EM4097 Chip has a low power consumption, making it more economical than many RFID chips.

Furthermore, the EM4097 chip features a complementary metal-oxide-semiconductor (CMOS) incorporated transceiver circuit useful for RFID base-station applications.

In order to power the transponder, the EM4097 Chip impacts the antenna driving with carrier-frequency. Furthermore, the EM4097 Chip enables the writable transponder to transmit data using amplitude modulation.

Data is transferred from the transponder via phase or amplitude demodulation. Finally, it communicates with the microprocessor through a micro-coulombs interface.

Animal ID readers and hand-held low-frequency readers can make use of the EM4097 Chip.

Chip EM4450

EM4450 is one of the latest EM series chips. The device is a 1-kbit, low-frequency, contactless ID. This chip incorporates a complementary metal-oxide-semiconductor (CMOS) circuit useful for electrical read/write radio frequency transponders.

There is an EEPROM of 1 Kbit on the EM4450 Chip that can be remodeled by any user. The remodeling or configuration allows for a read-protected area, a write-inhibited area with a read-area output with a never-ending power supply.

Every read and write protected function of the EM4450 Chip can be secured with a 32-bit password. Although it is easy and feasible to update the password, it cannot be read. Together with the device identification, the serial number code is laser-programmed. This makes every Chip different and unique.

By modulating the electromagnetic field's amplitude, the EM4450 Chip sends data to the transceiver. In the same way, it receives commands and data. The EEPROM can be programmed to update the password, read a unique memory region, and reset the logic with simple commands.

A tuned circuit's coil is the only external component that matters in this case. The Chip also incorporates the rest of the functions.

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

How do they differ?

You must be sure of what you need an EM chip for before you select one. The EM chips mentioned in this piece each have their own unique characteristics. EM chips also have variable features, such as bit size, memory capacity, and many others.

To conclude, you must be sure about your specific needs before choosing an EM chip based on what you need it for.

In addition, most EM chips require low power to operate. Therefore, you shouldn't be concerned about touching the power capacity of any EM chip. Before making any decision, it is important to contact a professional if you aren't sure which one is right for you.

While EM chips all have similar features, it is best to be fully certain before buying any.
