MF0ICU1
MIFARE Ultralight contactless single-ticket IC
8. Functional description
8.1 Block description
The MF0ICU1 chip consists of a 512-bit EEPROM, RF interface and Digital Control Unit
(DCU). Energy and data are transferred via an antenna consisting of a coil with a small
number of turns which is directly connected to the MF0ICU1. No further external
components are necessary. Refer to the document Ref. 6 “MIFARE (Card) Coil Design
Guide” for details on antenna design.
• RF interface:
– Modulator/demodulator
– Rectifier
– Clock regenerator
– Power-On Reset (POR)
– Voltage regulator
• Anticollision: Multiple cards may be selected and managed in sequence
• Command interpreter: Processes commands supported by the MF0ICU1 to access
the memory
• EEPROM interface
• EEPROM: 512 bits, organized in 16 pages of 4 bytes per page.
– 80 bits reserved for manufacturer data
– 16 bits used for the read-only locking mechanism
– 32 bits available as OTP area
– 384 bits user programmable Read/Write memory
