General Description
The A29040C is a 5.0 volt-only Flash memory organized as 524,288 bytes of 8 bits each. The 512 Kbytes of data are further divided into eight sectors of 64 Kbytes each for flexible sector erase capability. The 8 bits of data appear on I/O0 - I/O7 while the addresses are input on A0 to A18. The A29040C is offered in 32-pin PLCC, TSOP, and PDIP packages.

FEATUREs
■ 5.0V ± 10% for read and write operations
■ Access time:
    - 55ns (max.)
■ Current:
    - 20mA typical active read current
    - 30mA typical program/erase current
    - 6μA typical CMOS standby
■ Flexible sector architecture
    - 8 uniform sectors of 64 Kbyte each
    - Any combination of sectors can be erased
    - Supports full chip erase
    - Sector protection:
       A hardware method of protecting sectors to prevent any inadvertent program or erase operations within that sector
■ Extended operating temperature range: -40°C~+85°C for –U series
■ Embedded Erase Algorithms
    - Embedded Erase algorithm will automatically erase the entire chip or any combination of designated sectors and verify the erased sectors
    - Embedded Program algorithm automatically writes and verifies bytes at specified addresses
■ Minimum 100,000 program/erase cycles per sector
■ 20-year data retention at 125ºC
    - Reliable operation for the life of the system
■ Compatible with JEDEC-standards
    - Pinout and software compatible with single-powersupply Flash memory standard
    - Superior inadvertent write protection
■ Data Polling and toggle bits
    - Provides a software method of detecting completion of program or erase operations
■ Erase Suspend/Erase Resume
    - Suspends a sector erase operation to read data from, or program data to, a non-erasing sector, then resumes the erase operation
■ Package options
    - 32-pin P-DIP, PLCC, or TSOP (Forward type)
    - All Pb-free (Lead-free) products are RoHS compliant
