The EM4200 is a low-frequency (LF) RFID chip developed by EM Microelectronic, designed for use in read-only contactless identification systems. It’s a direct upgrade to the older EM4100/4102 series, offering better performance and flexibility. Here are its key technical characteristics:

  • Operating frequency: 100–150 kHz (typically 125 kHz)
  • Memory: 128-bit laser-programmed ROM (options for 64 or 96 bits)
  • Data encoding: Supports Manchester, Biphase, PSK, and FSK2 encoding schemes
  • Resonant capacitor: On-chip options of 0 pF, 75 pF, or 250 pF (mask selectable)
  • Modulation: Amplitude Shift Keying (ASK)
  • Power supply: Powered by the electromagnetic field from the reader (no battery required)
  • UID: Factory-programmed unique identifier
  • Temperature range: –40°C to +85°C
  • Applications: Access control, animal ID (ISO 11785 FDX-B), logistics, anti-counterfeiting, and industrial automation

It’s a solid, energy-efficient chip for systems that require simple, secure identification without the need for rewritable memory.

 

General description

The circuit is powered by an external coil placed in an electromagnetic field, and gets its master clock from the same field via one of the coil terminals. By turning on and off the modulation current, the chip will send back the 64 bits of information contained in a factor programmed memory array. The programming of the chip is performed by laser fusing of polysilicon links in order to store a unique code on each chip. The CARD has several metal options which are used to define the code type and data rate. Data rates of 64, 32 and 16 periods of carrier frequency per data bit are available. Data can be coded as Manchester, Biphase or PSK. Due to low power consumption of the logic core, no supply buffer capacitor is required. Only an external coil is needed to obtain the chip function. A parallel resonance capacitor of 78pF is also integrated.
