GENERAL DESCRIPTION

The Am29F040 is a 4 Mbit, 5.0 Volt-only Flash memory

organized as 512 Kbytes of 8 bits each. The Am29F040

is offered in a 32-pin package. This device is designed

to be programmed in-system with the standard system

which controls the erase and programming circuitry.

Write cycles also internally latch addresses and data

needed for the programming and erase operations.

Reading data out of the device is similar to reading

from 12.0 Volt Flash or EPROM devices.

5.0 V V

supply. A 12.0 V V

is not required for

write or erase operations. The device can also be

reprogrammed in standard EPROM programmers.

The Am29F040 is programmed by executing the pro-

gram command sequence. This will invoke the Embed-

ded Program Algorithm which is an internal algorithm

that automatically times the program pulse widths and

veriﬁes proper cell margin. Typically, each sector can

be programmed and veriﬁed in less than one second.

Erase is accomplished by executing the erase com-

mand sequence. This will invoke the Embedded Erase

Algorithm which is an internal algorithm that automati-

cally preprograms the array if it is not already pro-

grammed before executing the erase operation. During

erase, the device automatically times the erase pulse

widths and veriﬁes proper cell margin.

The standard Am29F040 offers access times between

55 ns and 150 ns, allowing operation of high-speed

microprocessors without wait states. To eliminate bus

contention the device has separate chip enable (CE),

write enable (WE) and output enable (OE) controls.

The Am29F040 is entirely command set compatible

with the JEDEC single-power-supply Flash standard.

Commands are written to the command register using

standard microprocessor write timings. Register con-

tents serve as input to an internal state machine
