FEATURES:
Data Sheet
Single 3.0-3.6V Read and Write Operations
Serial Interface Architecture
– SPI Compatible: Mode 0 and Mode 3
33 MHz Max Clock Frequency
Superior Reliability
– Endurance: 100,000 Cycles (typical) – Greater than 100 years Data Retention
Low Power Consumption:
– Active Read Current: 7 mA (typical) – Standby Current: 8 µA (typical)
Flexible Erase Capability
– Uniform 4 KByte sectors – Uniform 32 KByte overlay blocks
Fast Erase and Byte-Program:
– Chip-Erase Time: 70 ms (typical) – Sector- or Block-Erase Time: 18 ms (typical) – Byte-Program Time: 14 µs (typical)
Auto Address Increment (AAI) Programming
– Decrease total chip programming time over Byte-Program operations
End-of-Write Detection
– Software Status
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
