The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings Memory Cell Characteristics (Vcc=2.5V to 5.5V) Limits Parameter Unit Condition Min Typ Max 1,000,000 - - TimesTa85C (Note1) Endurance 500,000 - - TimesTa105C 300,000 - - TimesTa125C 100 - - YearsTa25C (Note1) Data Retention 60 - - YearsTa105C 50 - - YearsTa125C (Note1) Not 100% TESTED Recommended Operating Ratings Parameter Symbol Limits Unit Supply Voltage Vcc 2.5 to 5.5 V Input Voltage V 0 to Vcc IN Input / Output Capacitance (Ta=25C, frequency=5MHz) Parameter Symbol Min Max Unit Conditions (Note1) Input Capacitance C 8 V =GND IN IN pF (Note1) Output Capacitance C 8 V =GND OUT OUT (Note1) Not 100% TESTED Electrical Characteristics (Unless otherwise specified, Ta=-40C to +125C, Vcc=2.5V to 5.5V) Limits Parameter Symbol Unit Conditions Min Typ Max H Input Voltage V 0.7xVcc Vcc+0.3 V 2.5V Vcc5.5V IH L Input Voltage V -0.3 0.3xVcc V 2.5V Vcc5.5V IL L Output Voltage V 0 0.4 V I =2.1mA OL OL H Output Voltage V Vcc-0.5 Vcc V I =-0.4mA OH OH Input Leakage Current I -10 10 AV =0V to Vcc LI IN Output Leakage Current I -10 10 AV =0V to Vcc, CSB=Vcc LO OUT (Note1) Vcc=2.5V, f =5MHz, t =5ms, SCK E/W 2.0 I mA V /V =0.9Vcc/0.1Vcc, SO=OPEN CC1 IH IL (Note2) 2.5 Operating Current Byte Write, Page Write (Note1) (Write) Vcc=5.5V, f =5MHz, t =5ms, SCK E/W 3.0 I mA V /V =0.9Vcc/0.1Vcc, SO=OPEN CC2 IH IL (Note2) 5.5 Byte Write, Page Write Vcc=2.5V, f =5MHz, V /V =0.9Vcc/0.1Vcc SCK IH IL I 1.5 mA CC3 Operating Current SO=OPEN, Read, Read Status Register (Read) Vcc=5.5V, f =5MHz, V /V =0.9Vcc/0.1Vcc SCK IH IL I 2.0 mA CC4 SO=OPEN, Read, Read Status Register Vcc=5.5V Standby Current I 10 A SB CSB=Vcc, SCK=SI=Vcc or GND, SO=OPEN (Note1) BR35H160/320-WC (Note2) BR35H640/128-WC www.rohm.com TSZ02201-0R1R0G100170-1-2 2012 ROHM Co., Ltd.
