W29C020C - 256K x 8 CMOS FLASH MEMORY

General Description

The W29C020C is a 2-megabit, 5-volt only CMOS flash memory organized as 256K × 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.

Key Features

  • Single 5-volt write (erase and program) operations.
  • Fast page-write operations.
  • 128 bytes per page.
  • Page write (erase/program) cycle: 10 mS (max. ).
  • Effective byte-write (erase/program) cycle time: 39 µS.
  • Optional software-protected data write.
  • Fast chip-erase operation: 50 mS.
  • Two 8 KB boot blocks with lockout.
  • Whole chip cycling: 10K (typ. ).
  • Read access time: 70/90/120 nS.
  • Twenty-year data retent.

W29C020C 256K × 8 CMOS FLASH MEMORY GENERAL DESCRIPTION The W29C020C is a 2-megabit, 5-volt only CMOS flash memory organized as 256K × 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 W29C020C results in fast write (erase/program) operations with extremely low current consumption compared to other comparable 5volt 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 − 128 bytes per page − Page write (erase/program) cycle: 10 mS (max.
