GENERAL DESCRIPTION

The Am29F100 is a 1 Mbit, 5.0 Volt-only Flash memory organized as 131,072 bytes or 65,536 words. The Am29F100 is offered in 44-pin SO and 48-pin TSOP packages. Word-wide data appears on DQ0-DQ15; byte-wide data on DQ0-DQ7. The 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 programmed or erased in standard EPROM programmers.

DISTINCTIVE CHARACTERISTICS

■ Top or bottom boot block configurations available

■ Sector protection

— Hardware-based feature that disables/re-enables

program and erase operations in any

combination of sectors

— Sector protection/unprotection can be

implemented using standard PROM

programming equipment

— Temporary Sector Unprotect feature allows in

system code changes in protected sectors

■ Embedded Algorithms

— Embedded Erase algorithm automatically

pre-programs and erases the chip or any

combination of designated sector
