GENERAL DESCRIPTION
●The Am29F080B is an 8 Mbit, 5.0 volt-only Flash memory organized as 1,048,576 bytes. The 8 bits of data
●appear on DQ0–DQ7. The Am29F080B is offered in 40-pin TSOP and 44-pin SO packages. This device is
●designed to be programmed in-system with the standard system 5.0 volt VCCsupply. A 12.0 volt VPPis not required for program or erase operations. The device can also be programmed in standard EPROM programmers.
●DISTINCTIVE CHARACTERISTICS
●■5.0 V ±10%, single power supply operation
●— Minimizes system level power requirements
●■Manufactured on 0.32 µm process technology
●— Compatible with 0.5 µm Am29F080 device
●■High performance
●— Access times as fast as 55 ns
●■Low power consumption
●— 25 mA typical active read current
●— 30 mA typical program/erase current
●— 1 µA typical standby current (standard access time to active mode)
●■Flexible sector architecture
●— 16 uniform sectors of 64 Kbytes each
●— Any combination of sectors can be erased.
●— Supports full chip erase
●— Group sector protection:
● A hardware method of locking sector groups to prevent any program or erase operations within that sector group
● Temporary Sector Group Unprotect allows code changes in previously locked sectors
●■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 bytes at specified addresses
●■Minimum 1,000,000 program/erase cycles per sector guaranteed
●■20-year data retention at 125°C
●— Reliable operation for the life of the system
●■Package options
●— 40-pin TSOP
●— 44-pin SO
●■Compatible with JEDEC standards
●— Pinout and software compatible with single-power-supply Flash standard
●— Superior inadvertent write protection
●■Data# Polling and toggle bits
●— Provides a software method of detecting program or erase cycle completion
●■Ready/Busy# output (RY/BY#)
●— Provides a hardware method for detecting program or erase cycle completion
●■Erase Suspend/Erase Resume
●— Suspends a sector erase operation to read data from, or program data to, a non-erasing sector, then resumes the erase operation
●■Hardware reset pin (RESET#)
●— Resets internal state machine to the read mode
●■Command sequence optimized for mass storage
●— Specific addresses not required for unlock cycles
