W49L201

Preliminary W49L201 128K × 16 CMOS FLASH MEMORY GENERAL DESCRIPTION The W49L201 is a 2-megabit, 3.3-volt only CMOS flash memory organized as 128K × 16 bits. The device can be programmed and erased in-system with a standard 3.3V power supply. A 12-volt VPP is not required. The unique cell architecture of the W49L201 results in fast program/erase operations with extremely low current consumption (compared to other comparable 3.3-volt flash memory products). The device can also be programmed and erased using standard EPROM programmers. FEATURES Single 3.3-volt operations: − 3.3-volt Read/Erase/Program Fast Program operation: − Word-by-Word programming: 50 µS (max.) Fast Erase operation: 100 mS (typ.) Fast Read access time: 70/90 nS Endurance: 10K cycles (typ.) Ten-year data retention Hardware data protection Sector configuration − One 8K words Boot Block with lockout protection − Two 8K words Parameter Blocks − One 104K words (208K bytes) Mai...
