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
■ Single power supply operation
— 5.0 V ± 10% for read, erase, and program operations
— Simplifies system-level power requirements
■ High performance
— 70 ns maximum access time
■ Low power consumption
— 20 mA typical active read current for byte mode
— 28 mA typical active read current for word mode
— 30 mA typical program/erase current
— 25 µA typical standby current
■ Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
one 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
one 32 Kword sectors (word mode)
— Any combination of sectors can be erased
— Supports full chip erase
■ 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
— Embedded Program algorithm automatically
programs and verifies data at specified address
■ Minimum 100,000 program/erase cycles guaranteed
■ 20-year data retention at 125°C
— Reliable operation for the life of the system
■ Package options
