W49F002U

W49F002U 256K × 8 CMOS FLASH MEMORY GENERAL DESCRIPTION The W49F002U is a 2-megabit, 5-volt only CMOS flash memory organized as 256K × 8 bits. The device can be programmed and erased in-system with a standard 5V power supply. A 12-volt VPP is not required. The unique cell architecture of the W49F002U results in fast program/erase operations with extremely low current consumption (compared to other comparable 5-volt flash memory products). The device can also be programmed and erased using standard EPROM programmers. FEATURES Single 5-volt operations: − 5-volt Read − 5-volt Erase − 5-volt Program Fast Program operation: − Byte-by-Byte programming: 35 µS (typ.) Fast Erase operation: 100 mS (typ.) Fast Read access time: 70/90/120 nS Endurance: 10K cycles (typ.) Ten-year data retention Hardware data protection One 16K byte Boot Block with Lockout protection Two 8K byte Parameter Blocks Two Main Memory Blocks (96K, 128K) Bytes Low po...
