General Description
The A29400A is a 5.0 volt only Flash memory organized as 524,288 bytes of 8 bits or 262,144 words of 16 bits each. The A29400A offers the RESET function. The 512 Kbytes of data are further divided into eleven sectors for flexible sector erase capability. The 8 bits of data appear on I/O0 - I/O7 while the addresses are input on A1 to A17; the 16 bits of data appear on I/O0~I/O15. The A29400A is offered in 48- pin TSOP package. This device is designed to be programmed in-system with the standard system 5.0 volt VCC supply. Additional 12.0 volt VPP is not required for insystem write or erase operations.

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
    - 16 Kbyte/ 8 KbyteX2/ 32 Kbyte/ 64 KbyteX7 sectors
    - 8 Kword/ 4 KwordX2/ 16 Kword/ 32 KwordX7 sectors
    - 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
■ Top or bottom boot block configurations available
■ 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
■ Hardware reset pin (RESET )
    - Hardware method to reset the device to reading array
        data
■ Package options
    - 48-pin TSOP (I)
    - All Pb-free (Lead-free) products are RoHS2.0 compliant
