... GENERAL DESCRIPTION The Am29F002 Family consists of 2 Mbit, 5.0 volt-only Flash memory devices organized as 262,144 bytes. The Am29F002 offers the RESET# function, the Am29F002N does not. The data appears on DQ7– DQ0. The device is offered in 32-pin PLCC, 32-pin TSOP, and 32-pin PDIP packages. This device is designed to be programmed in-system with the standard system 5 ...

... The system must write the Erase Resume command (address bits are “don’t care”) to exit the erase suspend mode and continue the sector erase operation. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the de- vice has resumed erasing. Am29F002/Am29F002N ...
