The split-gate cell design and thick oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. The SST39LF100 and SST39VF100 write (Program or Erase) with a single volt- age power supply of 3.0-3.6V and 2.7-3.6V, respectively. Featuring high performance Word-Program, the SST39LF/ VF100 devices provide a typical Word-Program time of 14 µsec. The devices use Toggle Bit or Data# Polling to detect the completion of the Program or Erase operation. To pro- tect against inadvertent write, the SST39LF/VF100 have on-chip hardware and software data protection schemes. Designed, manufactured, and tested for a wide spectrum of applications, the SST39LF/VF100 are offered with a guar- anteed endurance of 10,000 cycles. Data retention is rated at greater than 100 years. The SST39LF/VF100 devices are suited for applications that require convenient and economical updating of pro- gram, configuration, or data memory. For all system appli- cations, the SST39LF/VF100 significantly improve performance and reliability, while lowering power consump- tion. The SST39LF/VF100 inherently use less energy dur- ing Erase and Program than alternative flash technologies. The total energy consumed is a function of the applied volt- age, current, and time of application. Since for any given voltage range, the SuperFlash technology uses less cur- rent to program and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash technologies. The SST39LF/ VF100 also improve flexibility while lowering the cost for program, data, and configuration storage applications. The SuperFlash technology provides fixed Erase and Pro- gram times, independent of the number of Erase/Program cycles that have occurred. Therefore the system software or hardware does not have to be modified or de-rated as is necessary with alternative flash technologies, whose Erase and Program times increase with accumulated Erase/Pro- gram cycles. To meet surface mount requirements, the SST39LF/VF100 are offered in 40-lead TSOP and 48-ball TFBGA packages. See Figure 1 for pinout. Device Operation Commands are used to initiate the memory operation func- tions of the device. Commands are written to the device using standard microprocessor write sequences. A com- mand is written by asserting WE# low while keeping CE# low. The address bus is latched on the falling edge of WE# or CE#, whichever occurs last. The data bus is latched on the rising edge of WE# or CE#, whichever occurs first. SST39LF/VF1003.0 & 2.7V 1 Mb (x16) MPF memories |
