8 Megabit (1 M x 8-Bit/512 K x 16-Bit)
CMOS 5.0 Volt-only, Boot Sector Flash Memory—Die Revision 1
DISTINCTIVE CHARACTERISTICS
s Single power supply operation
— 5.0 Volt-only operation for read, erase, and
program operations
— Minimizes system level requirements
s Manufactured on 0.35 µm process technology
— Compatible with 0.5 µm Am29F800 device
s High performance
— 90 or 120 ns access time
s Low power consumption (typical values at 5
MHz)
— 1 µA standby mode current
— 20 mA read current (byte mode)
— 28 mA read current (word mode)
— 30 mA program/erase current
s Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
fifteen 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
fifteen 32 Kword sectors (word mode)
— Supports full chip erase
— Sector Protection features:
A hardware method of locking a sector to
prevent any program or erase operations within
that sector
Sectors can be locked via programming
equipment
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
s Top or bottom boot block configurations
available
s Embedded Algorithms
— Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
— Embedded Program algorithm automatically
writes and verifies data at specified addresses
s Minimum 1,000,000 write cycles per sector
guaranteed
s Compatibility with JEDEC standards
— Pinout and software compatible with single-
power-supply Flash
— Superior inadvertent write protection
s Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
s Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting
program or erase cycle completion
s 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
s Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data

PRODUCT TEST FLOW
Figure 1 provides an overview of AMD’s Known Good
Die test flow. For more detailed information, refer to the
Am29F800B product qualification database supple-
ment for KGD. AMD implements quality assurance pro-
cedures throughout the product test flow. In addition,
an off-line quality monitoring program (QMP) further
guarantees AMD quality standards are met on Known
Good Die products. These QA procedures also allow
AMD to produce KGD products without requiring or
implementing burn-in.
