• Manufacturer Part Number: P4069
• Description: 128 Bit Read/write Contactless Identification Device With Otp Function
• Manufacturer: EM Microelectronic

The EEPROM is organized in 8 words of 16 bits. EEPROM words are counted from 0 to 7. Bits in an EEPROM
word are counted from 0 to 15. When EEPROM readout is initiated (after POR or after return from command to
read mode) read out is started from word 0 and increments to word 7. Readout in a word is started by bit 0 and then
increments up to bit 15. After word 7 bit 15 is read readout continues with word 0 bit 0 without any pause. So it is
very important to organize data written in EEPROM in a way that reader can detect the position of bits in data
stream. For Manchester encoding Word 0 and word 4 are factory programmed and locked (see figure 7a), for BI-
phase encoding the 8 words are user free (see figure 7b and 7c). Following tables show how standard versions are
factory programmed.
EEPROM Configuration for Manchester encoding (Version 1 and 11)
EEPROM Configuration for BI-phase encoding and 64 RF cycles/bit data rate (Version 21)
EEPROM Configuration for BI-phase encoding and 32 RF cycles /bit data rate (Version 31)
