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
s Single power supply operation
â 5.0 V ± 10% for read, erase, and program
operations
â Simplifies system-level power requirements
s High performance
â 70 ns maximum access time
s Low power consumption
â 20 mA typical active read current for byte mode
â 28 mA typical active read current for word mode
â 30 mA typical program/erase current
â 25 µA typical standby current
s Flexible sector architecture
â One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
one 64 Kbyte sectors (byte mode)
â One 8 Kword, two 4 Kword, one 16 Kword, and
one 32 Kword sectors (word mode)
â Any combination of sectors can be erased
â Supports full chip erase
s Top or bottom boot block configurations
available
s Sector protection
â Hardware-based feature that disables/re-
enables program and erase operations in any
combination of sectors
â Sector protection/unprotection can be
implemented using standard PROM
programming equipment
â Temporary Sector Unprotect feature allows in-
system code changes in protected sectors
s Embedded Algorithms
â Embedded Erase algorithm automatically
pre-programs and erases the chip or any
combination of designated sector
â Embedded Program algorithm automatically
programs and verifies data at specified address
s Minimum 100,000 program/erase cycles
guaranteed
s Package options
â 44-pin SO
â 48-pin TSOP
s Compatible with JEDEC standards
â Pinout and software compatible with
single-power-supply flash
â Superior inadvertent write protection
s Data# Polling and Toggle Bits
â Provides a software method of detecting
program or erase cycle completion
s Ready/Busy pin (RY/BY#)
â Provides a hardware method for detecting
program or erase cycle completion
s Erase Suspend/Erase Resume
â Suspends an erase operation to read data from,
or program data to, a sector that is not being
erased, then resumes the erase operation
s Hardware RESET# pin
â Hardware method of resetting the device to
reading array data
