This device has been developed for - Maximum read current 150 A at 6.0V advanced, low-power applications such as personal - Standby current 1 A typical communications, and provides the systems designer 2 Industry standard two-wire bus protocol I C with flexibility through the use of many new user-pro- compatible grammable features. The 24XX65 offers a relocatable 8-byte page, or byte modes available 4K bit block of ultra-high-endurance memory for data that changes frequently. The remainder of the array, or 2 ms typical write cycle time, byte or page 60K bits, is rated at 1,000,000 erase/write (E/W) cycles 64-byte input cache for fast write loads ensured. The 24XX65 features an input cache for fast Up to 8 devices may be connected to the same write loads with a capacity of eight pages, or 64 bytes. bus for up to 512K bits total memory This device also features programmable security Including 100 kHz (1.8V Vcc < 4.5V) and 400 options for E/W protection of critical data and/or code kHz (4.5V VCC 6.0V) compatibility of up to fifteen 4K blocks. Functional address lines Programmable block security options allow the connection of up to eight 24XX65 s on the Programmable endurance options same bus for up to 512K bits contiguous EEPROM memory. Advanced CMOS technology makes this Schmitt Trigger, filtered inputs for noise device ideal for low-power nonvolatile code and data suppression applications. The 24XX65 is available in the standard Output slope control to eliminate ground bounce 8-pin plastic DIP and 8-pin surface mount SOIC Self-timed erase and write cycles package.
