Product Overview

The A29L040AL-70F is a Flash Memory organized as 524288 bytes of 8-bit each. The 512Kbytes of data are further divided into eight sectors of 64Kbytes each for flexible sector erase capability. The 8-bit of data appear on I/O0 - I/O7 while the addresses are input on A0 to A18. This device is designed to be programmed in-system with the standard system 3VCC supply. Additional 12VPP is not required for in-system write or erase operations. However, the A29L040A can also be programmed in standard EPROM programmers. The A29L040A has a second toggle bit, I/O2, to indicate whether the addressed sector is being selected for erase and also offers the ability to program in the Erase Suspend mode. The standard A29L040A offers access times of 70ns, allowing high-speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable, write enable and output enable controls.
  • Single power supply operation

  • Compatible with JEDEC-standards
  • Superior inadvertent write protection
  • Data polling and toggle bits
  • Erase suspend/erase resume
