Am29F100 Known Good Die
1 Megabit (128 K x 8-Bit/64 K x 16-Bit)
CMOS 5.0 Volt-only, Boot Sector Flash Memory—Die Revision 1
DISTINCTIVE CHARACTERISTICS
a73 Single power supply operation
—5.0 V ± 10% for read, erase, and program
operations
— Simplifies system-level power requirements
a73 High performance
— 120 ns maximum access time
a73 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
a73 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
a73 Top or bottom boot block configurations
available
a73 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
a73 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
a73 Minimum 100,000 program/erase cycles
guaranteed
a73 Compatible with JEDEC standards
— Pinout and software compatible with
single-power-supply flash
— Superior inadvertent write protection
a73 Data Polling and Toggle Bits
— Provides a software method of detecting
program or erase cycle completion
a73 Ready/Busy pin (RY/BY#)
— Provides a hardware method for detecting
program or erase cycle completion
a73 Erase Suspend/Erase Resume
— Suspends an erase operation to read data from,
or program data to, a sector that is not being
erased, then resumes the erase operation
a73 Hardware RESET# pin
— Hardware method of resetting the device to
reading array data
a73 Tested to datasheet specifications at
temperature
a73 Quality and reliability levels equivalent to
standard packaged components
