W29F102
64K × 16 CMOS FLASH MEMORY
GENERAL DESCRIPTION
The W29F102 is a 1-megabit, 5-volt only CMOS flash memory organized as 64K × 16 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 W29F102 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:
− Word-by-Word programming: 50 µS (max.)
• Fast Erase operation: 100 mS (typ.)
• Fast Read access time: 45/50/55/70 nS
• Endurance: 1K/10K cycles (typ.)
• Ten-year data retention
• Hardware data protection
• 8K word Boot Block with Lockout protection
• Low power consumption
− Active current: 25 mA (typ.)
− Standby current: 20 µA (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 word-wide pinouts
• Available packages: 40-pin TSOP and 44-pin
