The SST39LF200A/400A/800Awrite (Program or Erase) with a 3.0-3.6V power supply. TheSST39VF200A/400A/800A write (Program or Erase) with a2.7-3.6V power supply. These devices conform to JEDECstandard pinouts for x16 memories.Featuring high performance Word-Program, theSST39LF200A/400A/800A and SST39VF200A/400A/800A devices provide a typical Word-Program time of 14usec. The devices use Toggle Bit or Data# Polling to detectthe completion of the Program or Erase operation. To pro-tect against inadvertent write, they have on-chip hardwareand software data protection schemes. Designed, manu-factured, and tested for a wide spectrum of applications,these devices are offered with a guaranteed endurance of10,000 cycles. Data retention is rated at greater than 100years.The SST39LF200A/400A/800A and SST39VF200A/400A/800A devices are suited for applications that require conve-nient and economical updating of program, configuration,or data memory. For all system applications, they signifi-cantly improve performance and reliability, while loweringpower consumption. They inherently use less energy dur-ing Erase and Program than alternative flash technologies.When programming a flash device, the total energy con-sumed is a function of the applied voltage, current, andtime of application. Since for any given voltage range, theSuperFlash technology uses less current to program andhas a shorter erase time, the total energy consumed duringany Erase or Program operation is less than alternativeflash technologies. These devices also improve flexibilitywhile lowering the cost for program, data, and configurationstorage applications.The SuperFlash technology provides fixed Erase and Pro-gram times, independent of the number of Erase/Programcycles that have occurred. Therefore the system softwareor hardware does not have to be modified or de-rated as isnecessary with alternative flash technologies, whose Eraseand Program times increase with accumulated Erase/Pro-gram cycles.To meet surface mount requirements, the SST39LF200A/400A/800A and SST39VF200A/400A/800A are offered inboth 48-lead TSOP packages and 48-ball TFBGA pack-ages.
