GENERAL DESCRIPTION
The W39V040A is a 4-megabit, 3.3-volt only CMOS flash memory organized as 512K ×8 bits. For flexible erase capability, the 4Mbitsof data are divided into 8 uniform sectors of 64 Kbytes, which are composed of 16 smaller even pages with 4 Kbytes. The device can be programmed and erased in-system with a standard 3.3V power supply.

FEATURES

−Byte-by-Byte programming: 35 µS (typ.)
• Fast Erase Operation:
−Chip erase 100 mS (max.)
−Sector erase 25 mS (max.)
−Page erase 25 mS (max.)
• Fast Read access time: Tkq 11 nS
• Endurance: 10K cycles (typ.)
• Twenty-year data retention
• 8 Even sectors with 64K bytes each, which is composed of 16 flexible pages with 4K bytes
• Any individual sector or page can be erased
•Hardware protection:
−Optional 16K byte or 64K byte Top Boot Block with lockout protection
−#TBL & #WP support the whole chip hardware protection
•Flexible 4K-page size can be used as Parameter Blocks
• Low power consumption
−Active current: 12.5 mA (typ. for LPC mode)
• Automatic program and erase timing with internal VPPgeneration
• End of program or erase detection
−Toggle bit
−Data polling
• Latched address and data
• TTL compatible I/O
• Available packages: 32L PLCC, 32L STSOP
