GENERAL DESCRIPTION
The Am29F200A 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 Am29F200A is offered in 44-pin SO and 48-pin TSOP packages. 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

A hardware method of locking a sector to prevent any program or erase operations within hat 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
— Embedded Program algorithm automatically writes and verifies data at specified addresses
■ Minimum 100,000 write/erase cycles guaranteed
■ Package options
— 44-pin SO
— 48-pin TSOP
■ Compatible with JEDEC standards
— Pinout and software compatible with single-power-supply flash
— 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
