PRELIMINARY
Am29F800B
8 Megabit (1 M x 8-Bit/512 K x 16-Bit)
CMOS 5.0 Volt-only, Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
s Single power supply operation
â 5.0 Volt-only operation for read, erase, and
program operations
â Minimizes system level requirements
s Manufactured on 0.35 µm process technology
â Compatible with 0.5 µm Am29F800 device
s High performance
â Access times as fast as 55 ns
s Low power consumption (typical values at 5
MHz)
â 1 µA standby mode current
â 20 mA read current (byte mode)
â 28 mA read current (word mode)
â 30 mA program/erase current
s Flexible sector architecture
â One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
fifteen 64 Kbyte sectors (byte mode)
â One 8 Kword, two 4 Kword, one 16 Kword, and
fifteen 32 Kword sectors (word mode)
â Supports full chip erase
â 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
â Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
â Embedded Program algorithm automatically
writes and verifies data at specified addresses
s Minimum 1,000,000 program/erase cycles per
sector guaranteed
s Package option
â 48-pin TSOP
â 44-pin SO
s Compatibility 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 operation completion
s Ready/Busy# pin (RY/BY#)
â Provides a hardware method of 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 (RESET#)
â Hardware method to reset the device to reading
array data
