GENERAL DESCRIPTION
●The Am29LV081B is an 8 Mbit, 3.0 volt-only Flash memory organized as 1,048,576 bytes. The device is
●offered in a 40-pin TSOP package. The byte-wide (x8) data appears on DQ7–DQ0. This device requires only
●a single, 3.0 volt VCCsupply to perform read, program, and erase operations. A standard EPROM programmer can also be used to program and erase the device.
●DISTINCTIVE CHARACTERISTICS
●■Single power supply operation
●— 2.7 to 3.6 volt read and write operations for battery-powered applications
●■Manufactured on 0.32 µm process technology
●— Compatible with 0.5 µm Am29LV081 device
●■High performance
●— Access times as fast as 70 ns
●■Ultra low power consumption (typical values at 5 MHz)
●— 200 nA Automatic Sleep mode current
●— 200 nA standby mode current
●— 7 mA read current
●— 15 mA program/erase current
●■Flexible sector architecture
●— Sixteen 64 Kbyte sectors
●— 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 in-system or via programming equipment
● Temporary Sector Unprotect feature allows code changes in previously locked sectors
●■Unlock Bypass Program Command
●— Reduces overall programming time when issuing multiple program command sequences
●■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 write cycle guarantee per sector
●■20-year data retention at 125°C
●— Reliable operation for the life of the system
●■Package option
●— 40-pin TSOP
●■Compatibility with JEDEC standards
●— Pinout and software compatible with single power 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
●■Command sequence optimized for mass storage
●— Specific addresses not required for unlock cycles
