Overview
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 Fast page-write operations − 256 bytes per page − Page write (erase/program) cycle: 5 mS (typ.
) − Effective byte-write (erase/program) cycle time: 19.
5 µS − Optional software-protected data write • • Software and hardware data protection Low power consumption − Active current: 25 mA (typ.
) − Standby current: 20 µA (typ.
) • • Automatic write (erase/program) timing with intern...
