ADVANCE INFORMATION
APRIL 2003
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 +70°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.
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.
