1 Mbit / 2 Mbit / 4 Mbit (x8) Multi-Purpose Flash
SST39SF010A / SST39SF020A / SST39SF040
Data Sheet
The SST39SF010A / SST39SF020A / SST39SF040 are CMOS Multi-Purpose
Flash (MPF) devices manufactured with SST proprietary, high performance
CMOS SuperFlash technology. The split-gate cell design and thick oxide tunnel-
ing injector attain better reliability and manufacturability compared with alternate
approaches. The SST39SF010A / SST39SF020A / SST39SF040 write (Program
or Erase) with a 4.5-5.5V power supply, and conforms to JEDEC standard pinouts
for x8 memories
Features
• Organized as 128K x8 / 256K x8 / 512K x8
• Single 4.5-5.5V Read and Write Operations
• Superior Reliability
– Endurance: 100,000 Cycles (typical)
– Greater than 100 years Data Retention
• Low Power Consumption
(typical values at 14 MHz)
– Active Current: 10 mA (typical)
– Standby Current: 30 µA (typical)
• Sector-Erase Capability

Absolute Maximum Stress Ratings (Applied conditions greater than those listed under “Absolute
Maximum Stress Ratings” may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these conditions or conditions greater than those defined in the
operational sections of this data sheet is not implied. Exposure to absolute maximum stress rating con-
