W29C040 Product details

GENERAL DESCRIPTION

The  W29C040 is a 4-megabit, 5-volt only CMOS page mode Flash Memory organized as 512K  ´8 bits. The device can be written (erased and programmed) in-system with a standard 5V power supply. A 12-volt VPPis 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 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 mS

  - Optional software-protected data write

·  Fast chip-erase operation: 50 mS

·  Two 16 KB boot blocks with lockout

·  Page write (erase/program) cycles: 50K (typ.)

·  Read access time: 70/90/120 nS

·  Ten-year data retention

·  Software and hardware data protection

·  Low power consumption

  - Active current: 25 mA (typ.)

  - Standby current: 20 mA (typ.)

·Automaticwrite (erase/program) timing with internal VPP generation

·  End of write (erase/program) detection

- Toggle bit

- Data polling

·  Latched address and data

·  All inputs and outputs directly TTL compatible

·  JEDEC standard byte-wide pinouts

·  Available packages: 32-pin 600 mil DIP, TSOP and PLCC
