W29C040  
512K ´ 8 CMOS FLASH MEMORY  
GENERAL DESCRIPTION  
The W29C040 is a 4-megabit, 5-volt only CMOS page mode EEPROM organized as 512K ´ 8 bits.  
The device can be written (erased and programmed) in-system with a standard 5V power supply. A  
12-volt VPP is not required. The unique cell architecture of the W29C040 results in fast write (erase/  
program) operations with extremely low current consumption compared to other comparable 5-volt  
flash memory products. The device can also be written (erased and programmed) by using standard  
EPROM programmers.  
FEATURES  
· Single 5-volt write (erase and program)  
operations  
· Software and hardware data protection  
· Low power consumption  
· Fast page-write operations  
- 256 bytes per page  
- Active current: 25 mA (typ.)  
- Standby current: 20 mA (typ.)  
- Page write (erase/program) cycle: 5 mS  
(typ.)  
· Automatic write (erase/program) timing with  
internal VPP generation  
- Effective byte-write (erase/program) cycle  
time: 19.5 mS  
· End of write (erase/program) detection  
- Toggle bit  
- Optional software-protected data write  
· Fast chip-erase operation: 50 mS  
· Two 16 KB boot blocks with lockout  
- Data polling  
· Latched address and data  
· All inputs and outputs directly TTL compatible  
· JEDEC standard byte-wide pinouts  
· Available packages: TSOP and PLCC  
· Typical page write (erase/program) cycles:  
1K/10K (typ.)  
· Read access time: 90/120 nS  
· Ten-year data retention  
Publication Release Date: May 1999
