No more than one output shorted at a time.DescriptionThe SST39LF100 devices are 64K x16 CMOS Multi- Purpose Flash (MPF) manufactured with SST's proprietary, high performance CMOS SuperFlash technology. 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 voltage 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 protect 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 guaranteed endurance of 10,000 cycles. Data retention is rated at greater than 100 years.
The SST39LF100 devices are suited for applications that require convenient and economical updating of program, configuration, or data memory. For all system applications, the SST39LF/VF100 significantly improve performance and reliability, while lowering power consumption.
The SST39LF100 inherently use less energy during Erase and Program than alternative flash technologies. The total energy consumed is a function of the applied voltage, current, and time of application. Since for any given voltage range, the SuperFlash technology uses less current 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 Program 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/Program 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.
