16 Megabit 2M x 8Bit/1M x 16Bit CMOS 3V-only Boot Sector Flash Memory
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

■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
