2-Mbit SPI Serial Flash  
SST25VF020  
Not Recommended for New Designs  
Microchip Technology's serial Flash family features a four-wire, SPI-compatible  
interface that allows for a low pin count package occupying less board space and  
ultimately lowering total system costs. SST25VF020 SPI serial Flash memory is  
manufactured with 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.  
Features  
• Single 2.7V-3.6V Read and Write Operations  
• End-of-Write Detection  
– Software Status  
• Serial Interface Architecture  
• Hold Pin (HOLD#)  
– SPI Compatible: Mode 0 and Mode 3  
– Suspends a serial sequence to the memory  
without deselecting the device  
• 20 MHz Max Clock Frequency  
• Superior Reliability  
• Write Protection (WP#)  
– Endurance: 100,000 cycles (typical)  
– Greater than 100 years data retention  
– Enables/Disables the Lock-Down function of the  
STATUS register  
• Low Power Consumption:  
• Software Write Protection  
– Active Read Current: 7 mA (typical)  
– Standby Current: 8 µA (typical)  
– Write protection through Block-Protection bits in  
STATUS register  
• Flexible Erase Capability  
• Temperature Range  
– Uniform 4-Kbyte sectors  
– Commercial: 0°C to +70°C  
– Industrial: -40°C to +85°C  
– Extended: -20°C to +85°C  
– Uniform 32-Kbyte overlay blocks  
• Fast Erase and Byte Program:  
• Packages Available  
– Chip-Erase Time: 70 ms (typical)  
– Sector- or Block-Erase Time: 18 ms (typical)  
– Byte-Program Time: 14 µs (typical)  
– 8-lead SOIC 150 mil body width  
– 8-contact WSON (5mm x 6mm)  
• Auto Address Increment (AAI) Programming  
• All non-Pb (lead-free) devices are RoHS compliant  
– Decrease total chip programming time over Byte
