GENERAL DESCRIPTION
The Am29LV002 is a 2 Mbit, 3.0 Volt-only Flash memory organized as 262,144 bytes. The device is offered in a 40-pin TSOP package. The byte-wide (x8) data appears on DQ7–DQ0. All read, program, and erase operations are accomplished using only a single power supply. The device can also be programmed in standard EPROM programmers.
DISTINCTIVE CHARACTERISTICS
■ Single power supply operation
— Full voltage range: 2.7 to 3.6 volt read and write operations for battery-powered applications
— Regulated voltage range: 3.0 to 3.6 volt read and write operations and for compatibility with high performance 3.3 volt microprocessors
■ High performance
— Full voltage range: access times as fast as 100 ns
— Regulated voltage range: access times as fast as 90 ns
■ Ultra low power consumption (typical values at 5 MHz)
— Automatic Sleep Mode: 200 nA
— Standby mode: 200 nA
— Read mode: 10 mA
— Program/erase mode: 20 mA
■ Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and three 64 Kbyte sectors
— Supports control code and data storage on a single device
— Sector Protection features:
A hardware method of locking a sector to prevent any program or erase operations within that sector
Temporary Sector Unprotect feature allows code changes in previously locked sectors
■ Top or bottom boot block configurations available
■ Embedded Algorithms
— Embedded Erase algorithms automatically preprogram and erase the entire chip or any combination of designated sectors
— Embedded Program algorithms automatically write and verify bytes or words at specified addresses
■ Typical 1,000,000 write cycles per sector
(100,000 cycles minimum guaranteed)
■ 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 feature
— 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 the read mode
