GENERAL DESCRIPTION
The Am29F200B is a 2 Mbit, 5.0 Volt-only Flash memory organized as 262,144 bytes or 131,072 words. The 8 bits of data appear on DQ0–DQ7; the 16 bits on DQ0–DQ15. The Am29F200B is offered in 44-pin SO and 48-pin TSOP packages. The device is also available in Known Good Die (KGD) form. For more information, refer to publication number 21257. This device is designed to be programmed in-system with the standard system 5.0 volt VCC supply. A 12.0 volt VPP is not required for program or erase operations. The device can also be reprogrammed in standard EPROM programmers.

DISTINCTIVE CHARACTERISTICS
■ 5.0 V ± 10% for read and write operations
    — Minimizes system level power requirements
■ Manufactured on 0.32 µm process technology
    — Compatible with 0.5 µm Am29F200A device
■ High performance
    — Access times as fast as 45 ns
■ Low power consumption
    — 20 mA typical active read current (byte mode)

■ Sector erase architecture
    — One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and three 64 Kbyte sectors (byte mode)
    — One 8 Kword, two 4 Kword, one 16 Kword, and three 32 Kword sectors (word mode)
    — Supports full chip erase
    — Sector Protection features:
    A hardware method of locking a sector to prevent any program or erase operations within that sector
    Sectors can be locked via programming equipment Temporary Sector Unprotect feature allows code changes in previously locked sectors
■ Top or bottom boot block configurations available
■ Embedded Algorithms
    — Embedded Erase algorithm automatically preprograms and erases the entire chip or any combination of designated sectors

    — Superior inadvertent write protection
■ Data# Polling and Toggle Bit
    — Detects program or erase cycle completion
■ Ready/Busy# output (RY/BY#)
    — Hardware method for detection of program or erase cycle completion
■ Erase Suspend/Erase Resume
    — Supports reading data from a sector not being erased
■ Hardware RESET# pin
    — Resets internal state machine to the reading array data
