Distinctive Characteristics

Architectural Advantages

■ Single Power Supply Operation

– Full voltage range: 2.7 to 3.6V read and write operations

■ Memory Architecture

– Uniform 64 kB sectors

– Top or bottom parameter block (Two 64-kB sectors

broken down into sixteen 4-kB sub-sectors each) for

each Flash die

– Uniform 256 kB sectors (no 4-kB sub-sectors)

– 256-byte page size

■ Program

– Page Program (up to 256 bytes) in 1.5 ms (typical)

– Program operations are on a page by page basis

– Accelerated programming mode via 9V W#/ACC pin

– Quad Page Programming

■ Erase

– Bulk erase function for each Flash die

– Sector erase (SE) command (D8h) for 64 kB and 256 kB

sectors

– Sub-sector erase (P4E) command (20h) for 4 kB sectors

(for uniform 64-kB sector device only)

– Sub-sector erase (P8E) command (40h) for 8 kB sectors

(for uniform 64-kB sector device only)

■ Cycling Endurance

– 100,000 cycles per sector typical

■ Data Retention

– 20 years typical

■ Device ID

– JEDEC standard two-byte electronic signature

– RES command one-byte electronic signature for backward

compatibility

■ One-time programmable (OTP) area on each Flash die for

permanent, secure identification; can be programmed and

locked at the factory or by the customer

■ CFI (Common Flash Interface) compliant: allows host

system to identify and accommodate multiple flash devices
