描述 Description

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
   — 44-pin SO
   — 48-pin TSOP (Continue ...)
