Am29LV128M Product Overview
128 Megabit (8 M x 16-Bit/16 M x 8-Bit) MirrorBit™ 3.0 Volt-only,
Uniform Sector Flash Memory with VersatileI/0™ Control
NOTE: For new designs, S29GL128M or S29GL128N supercedes Am29LV128M and is the factory-recommended migration path for this device. Please refer to the S29GL128M or S29GL128N Family Datasheet for specifications and ordering information.
General Description
The Am29LV128M is a 128 Mbit, 3.0 volt single power supply flash memory devices organized as 8,388,608 words or 16,777,216 bytes. The device has a 16-bit wide data bus that can also function as an 8-bit wide data bus by using the BYTE# input. The device can be programmed either in the host system or in standard EPROM programmers.
Distinctive Characteristics
Architectural Advantages
- Single power supply operation
- 3 volt read, erase, and program operations
- VersatileI/O™ control
- Device generates and tolerates voltages on CE# and DQ I/O as determined by the voltage on the VIO pin; operates from 1.65 to 3.6 V
- Manufactured on 0.23 µm MirrorBit process technology
- SecSi™ (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
- Two hundred fifty-six 32 Kword (64 Kbyte) sectors
- Compatibility with JEDEC standards
- Provides pinout and software compatibility for single-power supply Flash, and superior inadvertent write protection
- Minimum 100,000 erase cycle guarantee per sector
- 20-year data retention at 125°C

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 or byte programming time
- CFI (Common Flash Interface) compliant: allows host system to identify and accommodate multiple flash devices

Hardware Features
- Sector Group Protection: hardware-level method of preventing write operations within a sector group
- Temporary Sector Unprotect: VID -level method of changing code in locked sectors
- WP#/ACC input accelerates programming time (when high voltage is applied) for greater throughput during system production. Protects first or last sector regardless of sector protection settings
- Hardware reset input (RESET#) resets device
- Ready/Busy# output (RY/BY#) detects program or erase cycle completion
