Overview
- Address specification system using opcode input over a 3-wire interface (CLK, I/O, and RST)
- Automatic erasing and writing using a single 5 volt power supply Flexible memory-layout The memory is divided into 11 areas. Six areas containing 500 bytes are freely usable. Advanced security features
- Verification of IC card authenticity The IC passes entered data through a random number generator circuit on its way to output to provide a check of card validity.
- Protection against malicious experimentation Four or more unsuccessful attempts to access the IC card render it permanently unusable.
- Protection of individual memory areas on the card Read or write access to a memory area requires matches for both security and condition codes. There is also a condition code for permanently disabling re-write.
- Mixed configuration of EPROM and EEPROM Individual areas consist of EPROM or EEPROM. High reliability
- Write cycles: 10,000 times
- Data storage interval: 10 years I/O 2 3 (TOP VIEW) Note: This product is sold as wafers.
