GENERAL DESCRIPTION

The Am29LV008 is an 8 Mbit, 3.0 Volt-only Flash memory organized as 512 Kbytes of 8 bits each. For flexible erase and program capability, the 512 Kbits of data is divided into 19 sectors of one 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and fifteen 64 Kbytes. The data appears on DQ0–DQ7. The Am29LV008 is offered in a 40-pin TSOP package. This device is designed to be programmed in-system with the standard system 3.0 volt VCC supply. The device can also be reprogrammed in standard EPROM programmers.

■ Flexible sector architecture

— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and fifteen 64 Kbyte sectors

— Supports control code and data storage on a single device

— Sector Protection features:

A hardware method of locking a sector to prevent any program or erase operations within that sector

Temporary Sector Unprotect feature allows code changes in previously locked sectors

■ Top or bottom boot block configurations available

■ Embedded Algorithms

— Embedded Erase algorithms automatically preprogram and erase the entire chip or any combination of designated sectors

— Embedded Program algorithms automatically write and verify bytes or words at specified addresses

■ Minimum 100,000 write cycle guarantee per sector

■ Package option

— 40-pin TSOP

■ Compatibility with JEDEC standards

— Pinout and software compatible with single power 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

— Provides a hardware method of detecting program or erase cycle completion

■ Erase suspend/resume feature

— Provides the ability to suspend the erase operation in any sector, read data from or program data to any other sector, then return to the original sector and complete the initial erase operation

■ Hardware reset pin (RESET)

— Hardware method to reset the device to the read mode
