Product Overview

The SST39SF040-70-4C-PHE is a CMOS Multi-purpose Flash (MPF) device 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 with alternate approaches. The SST39SF040 write (program or erase) with a 4.5 to 5.5V power supply and conforms to JEDEC standard pinouts for x8 memories. Featuring high performance Byte-Program, the SST39SF040 device provide a maximum Byte-Program time of 20μsec. This device use toggle bit or data# polling to indicate the completion of Program operation. To protect against inadvertent write, they have on-chip hardware and Software data protection schemes. Designed, manufactured and tested for a wide spectrum of applications, this device is offered with a guaranteed typical endurance of 100000 cycles. Data retention is rated at greater than 100 years.
  • Latched address and data
