Description
The EM4056 is a CMOS integrated circuit intended foruse in contactless Read/Write transponders. The user’s configurable 2 kbits EEPROM memory contained in the chip is organised in 125 words of 16 bits, each word can be irreversibly protected against reading or/and writing attempts.
The user can define a password and protect part or all of the memory.
Features
? 2 kBits EEPROM organized in 125 words of 16 bits
? 3 words of 16 Bits Laser ROM for application number and serial number
? Programmable (OTP) Read and/or Write Protection on every word
? Programmable PIN coverage of the memory (0, 25, 50, 75 or 100 )
? Power check for EEPROM Write operation
? Reader Talk First communication protocol
? Data transmission performed by Amplitude Modulation (ASK) and Biphase (CDP) coding
? Data rate 2 KBauds (Bit Period = 64 periods of carrier frequency)
? 100 to 150kHz carrier frequency
? Long range Read/Write operations
? Block check of data transmission (CRC)
? Anticollision protocol based on unique ID number(unlimited number of tags)
? PIN Code identification linked with counter of false attempts
? On chip arithmetic operation (addition, comparison of secret and non secret data, etc.)
? 340pF ± 3 on chip Resonant Capacitor
? No external supply buffer capacitance
? On chip Rectifier and Voltage Limiter
Applications
? Ticketing
