1 / 2 page 1/2 DATA BRIEFING October 1999 Complete data available under NDA. ST1305B Memory Card IC 192 bit High Endurance EEPROM With Secure Logic Access Control s Single Supply Voltage (5 V) s Memory Divided Into: – 16 bits of Circuit Identification – 48 bits of Card Identification – 48 bits of Count Data – 16 bits of Certificate – 24 bits of Transport Code – 64 bits of Issuer Data s Counting Capability up to 262,144 s Circuit Protected by Transport Code for Delivery from ST to the Customer s 5 External Contacts Only (ISO 7816 Compatible) s Answer to Reset (Fully Compatible with ISO 7816-3) s E.S.D. Protection Greater Than 4000 V s Power-On and Low VCC Reset s 1 Million Erase/Write Cycles (minimum) s 10 Year Data Retention (minimum) s 5 ms Programming Time (typical) DESCRIPTION The ST1305B is a 192-bit EEPROM device with associated security logic to control memory ac- cess. The circuit includes counting capabilities and thus is very well adapted to prepaid card ap- plications. The ST1305B is protected by hard-wired security logic and special fuses. The memory is arranged as a matrix of 24x8 cells, accessed in a serial bit- Figure 1. Logic Diagram DS05B01 RST VCC ST1305B GND I/O CLK Table 1.
