The SST39WF800B is a 512K x16 CMOS Multi-Purpose Flash (MPF) manufactured with SST proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared to alternate approaches. The SST39WF800B writes (Program or Erase) with a 1.65-1.95V power supply. This device conforms to JEDEC standard pin assignments for x16 memories.

The SST39WF800B features high-performance Word-Programming which provides a typical Word-Program time of 28 µsec. It uses Toggle Bit or Data# Polling to detect the completion of the Program or Erase operation. On-chip hardware and software data protection schemes protects against inadvertent writes. Designed, manufactured, and tested for a wide spectrum of applications, the SST39WF800B is offered with a guaranteed typical endurance of 100,000 cycles. Data retention is rated at greater than 100 years.

The SST39WF800B is suited for applications that require convenient and economical updating of program, configuration, or data memory. It significantly improves performance and reliability of all system applications while lowering power consumption. It inherently uses less energy during Erase and Program than alternative flash technologies. When programming a flash device, the total energy consumed is a function of the applied voltage, current, and time of application. For any given voltage range, Super- Flash technology uses less current to program and has a shorter erase time; therefore, the total energy consumed during any Erase or Program operation is less than alternative flash technologies. These devices also improve flexibility while lowering the cost for program, data, and configuration storage applications.

SuperFlash technology provides fixed Erase and Program times independent of the number of Erase/Program cycles that have occurred. Consequently, 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 SST39WF800B is offered in a 48-ball TFBGA package and a 48-ball Micro- Package.
