| General Description The Am29LV160M 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 a 48-ball Fine-pitch BGA, 64-ball Fortified BGA, and 48-pin TSOP packages. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. The device requires only a single 3.0 volt power supply for both read and write functions, designed to be programmed in-system with the standard system 3.0 volt VCC supply. The device can also be programmed in standard EPROM programmers. Distinctive Characteristics Architectural Advantages ■ Single power supply operation — 3 V for read, erase, and program operations ■ Manufactured on 0.23 µm MirrorBitTM process technology — Fully compatible with Am29LV160D device ■ Secured Silicon Sector region — 128-word/256-byte sector for permanent, secure identification through an 8-word/16-byte random Electronic Serial Number, accessible through a command sequence — May be programmed and locked at the factory or by the customer ■ 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) ■ Compatibility with JEDEC standards — Provides pinout and software compatibility for single power supply flash, and superior inadvertent write protection ■ Top or bottom boot block configurations available ■ Mini-mum 100,000 erase cycle guarantee per sector ■ 20-year data retention at 125°C Performance Characteristics ■ High performance — Access times as fast as 70 ns — 0.7 s typical sector erase time ■ Low power consumption (typical values at 5 MHz) — 400 nA standby mode current — 15 mA read current — 40 mA program/erase current — 400 nA Automatic Sleep mode current ■ Package options — 48-ball Fine-pitch BGA — 64-ball Fortified BGA — 48-pin TSOP Software Features — Program Suspend & Resume: read other sectors before programming operation is completed — Erase Suspend & Resume: read/program other sectors before an erase operation is completed — Data# polling & toggle bits provide status — Unlock Bypass Program command reduces overall multiple-word programming time — CFI (Common Flash Interface) compliant: allows host system to identify and accommodate multiple flash devices Hardware Features — Sector Protection: hardware-level method of preventing write operations within a sector — Temporary Sector Unprotect: VID-level method of changing code in locked sectors — Hardware reset input (RESET#) resets device — Ready/Busy# output (RY/BY#) indicates program or erase cycle completion |
