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

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
