• Manufacturer Part Number: sle4406
• Description: Intelligent 88bit Eeprom Counter
• Manufacturer: Infineon Technologies Corporation

SLE 4406/06E is designed for applications in prepaid telephone cards. The chip consists of an
EEPROM memory of 88 bit, a ROM of 16 bits and a control/security unit.
Blocks marked by cross hatch - Defined by chip manufacturer
Counter, Identification Data (e.g. serial number, expiry date) and Data Areas.
Setting of the address counter is synchronously with the CLK.
The programming voltage for the EEPROM/PROM is generated internally.
Ensures a minimum and a maximum frequency and proper logical voltage levels.
