PRODUCT DESCRIPTION
●The 25 series Serial Flash family features a four-wire, SPI compatible interface that allows for a low pin-count pack age which occupies less board space and ultimately lowers total system costs. The SST25VF040B devices are enhanced with improved operating frequency and even lower power consumption.
●FEATURES:
●• Single Voltage Read and Write Operations
●– 2.7-3.6V
●• Serial Interface Architecture
●– SPI Compatible: Mode 0 and Mode 3
●• High Speed Clock Frequency
●– Up to 50/80 MHz
●• Superior Reliability
●– Endurance: 100,000 Cycles (typical)
●– Greater than 100 years Data Retention
●• Low Power Consumption:
●– Active Read Current: 10 mA (typical)
●– Standby Current: 5 µA (typical)
●• Flexible Erase Capability
●– Uniform 4 KByte sectors
●– Uniform 32 KByte overlay blocks
●– Uniform 64 KByte overlay blocks
●• Fast Erase and Byte-Program:
●– Chip-Erase Time: 35 ms (typical)
●– Sector-/Block-Erase Time: 18 ms (typical)
●– Byte-Program Time: 7 µs (typical)
●• Auto Address Increment (AAI) Programming
●– Decrease total chip programming time over
●Byte-Program operations
●• End-of-Write Detection
●– Software polling the BUSY bit in Status Register
●– Busy Status readout on SO pin in AAI Mode
●• Hold Pin (HOLD#)
●– Suspends a serial sequence to the memory
●without deselecting the device
●• Write Protection (WP#)
●– Enables/Disables the Lock-Down function of the
●status register
●• Software Write Protection
●– Write protection through Block-Protection bits in
●status register
●• Temperature Range
