FINAL
Am29F100
1 Megabit (128 K x 8-bit/64 K x 16-bit)
CMOS 5.0 Volt-only, Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
■ Single power supply operation
■ Embedded Algorithms
— 5.0 V ± 10% for read, erase, and program
— Embedded Erase algorithm automatically
pre-programs and erases the chip or any
combination of designated sector
operations
— Simplifies system-level power requirements
— Embedded Program algorithm automatically
programs and verifies data at specified address
■ High performance
— 70 ns maximum access time
■ Minimum 100,000 program/erase cycles
■ Low power consumption
guaranteed
— 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
■ Package options
— 44-pin SO
— 48-pin TSOP
■ Compatible with JEDEC standards
■ Flexible sector architecture
— Pinout and software compatible with
single-power-supply flash
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
one 64 Kbyte sectors (byte mode)
— Superior inadvertent write protection
— One 8 Kword, two 4 Kword, one 16 Kword, and
one 32 Kword sectors (word mode)
■ Data# Polling and Toggle Bits
— Provides a software method of detecting
program or erase cycle completion
— Any combination of sectors can be erased
— Supports full chip erase
■ Ready/Busy pin (RY/BY#)
■ Top or bottom boot block configurations
— Provides a hardware method for detecting
program or erase cycle completion
available
■ Sector protection
■ Erase Suspend/Erase Resume
— Hardware-based feature that disables/re-
enables program and erase operations in any
combination of sectors
— Suspends an erase operation to read data from,
or program data to, a sector that is not being
erased, then resumes the erase operation
— Sector protection/unprotection can be
implemented using standard PROM
programming equipment
■ Hardware RESET# pin
— Hardware method of resetting the device to
reading array data
— Temporary Sector Unprotect feature allows in-
system code changes in protected sectors
