Details

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 mS (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 power consumption - Active current: 25 mA (typ.) - Standby current: 20 mA (typ.) · Automatic program and erase timing with internal VPP generation · End of program or erase detection - Toggle bit - Data polling · Latched address and data · TTL compatible I/O · JEDEC standard byte-wide pinouts · Available packages: 32-pin DIP and 32-pin TSOP and 32-pin-PLCC
