EM4450 Datasheet 1-kbit Read/write Contactless Identification Device

Manufacturer: EM Microelectronic (Swatch Group)

Overview: EM MICROELECTRONIC - MARIN SA EM4450 1 KBit Read/Write Contactless Identification.

General Description

The EM4450 is a CMOS integrated circuit intended for use in electronic Read/Write RF Transponders.

The chip contains 1K Bit of EEPROM which can be configured by the user, allowing a write inhibited area, a read protected area, and a read area output continuously at power on.

The memory can be secured by using the 32 bit password for all write and read protected operations.

Key Features

  • 1 K bit of EEPROM organized in 32 words of 32 bits.
  • 32 bit Device Serial Number (Read Only Laser ROM).
  • 32 bit Device Identification (Read Only Laser ROM).
  • Power-On-Reset sequence.
  • Power Check for EEPROM write operation.
  • User defined Read Memory Area at Power On.
  • User defined Write Inhibited Memory Area.
  • User defined Read Protected Memory Area.
  • Data Transmission performed by Amplitude Modulation.
  • Two Data Rate Options 2 KBd (Opt64) or 4 KBd (Opt3.
