C1 C2 C3 C4 C5 C6 C7 C8 Vcc RST CLK FUS GND NC I/O PGM 16-KBIT SECURED SERIAL EEPROM FEATURES • 16K serial EEPROM with security features • Comply with ISO/IEC Standard 7816-3 Synchronous Protocol • Store and validate security codes • Four protected application zones • Provide transport code security • Single 5V power supply for read/write/erase operations • Low power operation: — 15 µA (max.) standby current — 3 mA (max.) read current at 300 KHz — 4 mA (max.) write/erase current • 2 ms read access time at 300 KHz; 5 ms write cycle time • 300 KHz serial clock rate • High ESD protection: > 4 KV • High reliability: — 1,000,000 erase/write cycles — 10 years data retention • Standard CMOS Process • Wide operating temperature range — 0°C to +7 0°C Commercial; –40°C to +85°C Industrial • Data access only after validation of security code • Permanent invalidation of device upon eight consecutive failed attempts to enter the correct security code • Separate read/write/erase access protections for each application zone • Allow the memory chip to be personalized if the internal security fuse is not blown. If the internal security fuse is blown, maximum security protection of the memory will always be enabled. ADVANCE INFORMATION APRIL 2003 DESCRIPTION IS23SC1604 is a low-cost, low-power, highly secured 16K bits (2K x 8) serial EEPROM. It is fabricated using ISSI’s advanced CMOS technology. The security features of IS23SC1604 provide high levels of memory security protection for smart card applications. The memory is partitioned into four application zones. Each individual application zone is protected by multiple security codes from unauthorized read/write/erase access to the zone. In addition, an internal security fuse is available for the card issuer to fully personalize the device before releasing it to customer. The device also features an internal high-voltage charge pump for memory programming, 1,000,000 write/erase cycles and ten years of data retention. Pin Configuration: 8-pin Plastic DIP |
