W49F002U Détails du produit

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
