available
s
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
s
Minimum 100,000 write cycle guarantee per
sector
s
Package option
— 40-pin TSOP
s
Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash

s
Data Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
s
Ready/Busy pin
— Provides a hardware method of detecting
program or erase cycle completion
s
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
s
Hardware reset pin (RESET)
— Hardware method to reset the device to the read
mode
GENERAL DESCRIPTION
The Am29LV008 is an 8 Mbit, 3.0 Volt-only Flash mem-
ory 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 pro-
grammed in-system with the standard system 3.0 volt
V
CC
supply. The device can also be reprogrammed in
standard EPROM programmers.
The Am29LV008 provides two levels of performance.
The first level offers access times as fast as 100 ns with
a V
CC
range as low as 2.7 volts, which is optimal for
battery powered applications. The second level offers a
