• Flexible Erase Capability
– Uniform 4 KByte Sectors
– Uniform 16 KByte overlay blocks
– Top Boot Block protection: 16 KByte
– Chip-Erase for PP Mode Only
• Single 3.0-3.6V Read and Write Operations
• Superior Reliability
– Endurance: 100,000 Cycles (typical)
– Greater than 100 years Data Retention
• Low Power Consumption
– Active Read Current: 6 mA (typical)
– Standby Current: 10 µA (typical)
• Fast Sector-Erase/Byte-Program Operation
– Sector-Erase Time: 18 ms (typical)
– Block-Erase Time: 18 ms (typical)
– Chip-Erase Time: 70 ms (typical)
– Byte-Program Time: 14 µs (typical)
– Chip Rewrite Time: 4 seconds (typical)
– Single-pulse Program or Erase
– Internal timing generation
• Two Operational Modes
– Low Pin Count (LPC) Interface mode for in-system operation
