AM29LV081B-90EC
NOR Flash Parallel 3V/3.3V 8Mbit 1M x 8Bit 90ns 40Pin TSOP
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
