●GENERAL DESCRIPTION
●The Am29LV160B is a 16 Mbit, 3.0 Volt-only Flash memory organized as 2,097,152 bytes or 1,048,576 words. The device is offered in 48-ball FBGA, 44-pin SO, and 48-pin TSOP packages. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device is designed to be programmed in-system with the standard system 3.0 volt VCCsupply. A 12.0 V VPPor 5.0 VCCare not required for write or erase operations. 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
●■Manufactured on 0.35 µm process technology
●■Supports Common Flash Memory Interface(CFI)
●■High performance
●— Full voltage range: access times as fast as 90 ns
●— Regulated voltage range: access times as fast as 80 ns
●■Ultra low power consumption (typical values at 5 MHz)
●— 200 nA Automatic Sleep mode current
●— 200 nA standby mode current
●— 9 mA read current
●— 20 mA program/erase current
●■Flexible sector architecture
●— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and thirty-one 64 Kbyte sectors (byte mode)
●— One 8 Kword, two 4 Kword, one 16 Kword, and thirty-one 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 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
●■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 write cycle guarantee per sector
●■Package option
●— 48-ball FBGA
●— 48-pin TSOP
●— 44-pin SO
●■CFI (Common Flash Interface) compliant
●— Provides device-specific information to the system, allowing host software to easily reconfigure for different Flash devices
●■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 (not
●available on 44-pin SO)
●■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
