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 VCC supply. A 12.0 V VPP or 5.0 VCC are 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 0.32 µm process technology ■ High performance — Full voltage range: access times as fast as 80 ns — Regulated voltage range: 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 — 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 ■ 20-year data retention at 125°C — Reliable operation for the life of the system ■ 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 singlepower 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
