EM4550 Datasheet 1 Kbit Read/write Contactless Identification Device

Manufacturer: EM Microelectronic (Swatch Group)

Overview: EM MICROELECTRONIC - MARIN SA EM4450 EM4550 1 KBit Read/Write Contactless Identification.

General Description

The EM4450/4550 is a CMOS integrated circuit intended for use in electronic Read/Write RF Transponders.

The difference between EM4450 and EM4550 is that EM4550 are bumped and has megapads for the two coils.

The chip contains 1 KBit 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.

Key Features

  • 1 KBit 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 (Opt32) Bit Period = 64 or 32 periods of field frequency 170 pF ±.
