GENERAL DESCRIPTION

The Am29LV010B is a 1 Mbit, 3.0 Volt-only Flash memory device organized as 131,072 bytes. The

Am29LV010B has a uniform sector architecture. The device is offered in 32-pin PLCC and 32-pin TSOP packages. The byte-wide (x8) data appears on DQ7-DQ0. All read, erase, and program operations are accomplished using only a single power supply. 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 55 ns

? Ultra low power consumption (typical values at 5 MHz)

— 200 nA Automatic Sleep mode current

— 200 nA standby mode current

— 7 mA read current

— 15 mA program/erase current

? Flexible sector architecture

— Eight 16 Kbyte

— Supports full chip erase

— Sector Protection features:

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 Mode Program Command

— Reduces overall programming time when issuing multiple program command sequences

? 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

— 32-pin TSOP

— 32-pin PLCC

? 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

? Erase Suspend/Erase Resume

— Supports reading data from or programming data to a sector that is not being erased
