PRODUCT DESCRIPTION
The SST36VF1601/1602 are 1M x16 CMOS Concurrent Read/Write Flash Memory 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 SST36VF1601/ 1602 write (Program or Erase) with a 2.7-3.6V power supply. The SST36VF1601/1602 devices conform to JEDEC standard pinouts for x16 memories.
Featuring high performance Word-Program, the SST36VF1601/1602 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 SST36VF1601/1602 devices have on-chip hardware and Software Data Protection schemes. Designed, manufactured, and tested for a wide spectrum of applications, the SST36VF1601/1602 devices are offered with a guaranteed endurance of 10,000 cycles. Data retention is rated at greater than 100 years.
The SST36VF1601/1602 are suited for applications that require convenient and economical updating of program, configuration, or data memory. For all system applications, the SST36VF1601/1602 significantly improve performance and reliability, while lowering power consumption.
The SST36VF1601/1602 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 SST36VF1601/1602 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 high density, surface mount requirements, the SST36VF1601/1602 are offered in 48-pin TSOP and 48- ball TFBGA packages. See Figures 3 and 4 for pinouts.
