AM29F800BB-55SIB - 8 Megabit (1 M x 8-Bit/512 K x 16-Bit) CMOS 5.0 Volt-only, Boot Sector Flash Memory
DISTINCTIVE CHARACTERISTICS
Single power supply operation
— 5.0 Volt-only operation for read, erase, and
program operations
— Minimizes system level requirements
Manufactured on 0.35 µm process technology
— Compatible with 0.5 µm Am29F800 device
High performance
— Access times as fast as 55 ns
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
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
Top or bottom boot block configurations
available
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
Minimum 1,000,000 program/erase cycles per
sector guaranteed
Package option
— 48-pin TSOP
— 44-pin SO
Compatibility with JEDEC standards
— Pinout and software compatible with singlepower-supply Flash
— Superior inadvertent write protection
Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
Ready/Busy pin (RY/BY)
— Provides a hardware method of detecting
program or erase cycle completion
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
Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data
