Description

The AT27C040 chip is a low-power, high-performance, 4,194,304-bit one-time pro-

grammable read-only memory (OTP EPROM) organized as 512K by 8 bits. The

AT27C040 requires only one 5V power supply in normal read mode operation. Any

byte can be accessed in less than 70 ns, eliminating the need for speed reducing

WAIT states on high-performance microprocessor systems.

0189F–EPROM–4/03

Atmel’s scaled CMOS technology provides low active power consumption, and fast program-

ming. Power consumption is typically 8 mA in active mode and less than 10 µA in standby

mode.

The AT27C040 is available in a choice of industry standard JEDEC-approved one-time pro-

grammable (OTP) plastic PDIP, PLCC and TSOP packages. The device features two-line

control (CE, OE) to eliminate bus contention in high-speed systems.

Atmel’s AT27C040 has additional features to ensure high quality and efficient production use.

The Rapid Programming Algorithm reduces the time required to program the part and guaran-

tees reliable programming. Programming time is typically only 100 µs/byte. The Integrated

Product Identification Code electronically identifies the device and manufacturer. This feature

is used by industry standard programming equipment to select the proper programming algo-

rithms and voltages.

Switching

Considerations

Switching between active and standby conditions via the Chip Enable pin may produce tran-

sient voltage excursions. Unless accommodated by the system design, these transients may

exceed datasheet limits, resulting in device non-conformance. At a minimum, a 0.1 µF high

frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This

capacitor should be connected between the V_CCand Ground terminals of the device, as close

to the device as possible. Additionally, to stabilize the supply voltage level on printed circuit

boards with large EPROM arrays, a 4.7 µF bulk electrolytic capacitor should be utilized, again

connected between the V_CCand Ground terminals. This capacitor should be positioned as

close as possible to the point where the power supply is connected to the array.

Absolute Maximum Ratings*

*NOTICE:

Stresses beyond those listed under “Absolute

Maximum Ratings” may cause permanent dam-

age to the device. This is a stress rating only and

functional operation of the device at these or any

other conditions beyond those indicated in the

operational sections of this specification is not

implied. Exposure to absolute maximum rating

Programming

Algorithm

A 100 µs CE pulse width is used to program. The address is set to the first location. V_CCis

raised to 6.5V and V_PPis raised to 13.0V. Each address is first programmed with one 100 µs

CE pulse without verification. Then a verification/reprogramming loop is executed for each

address. In the event a byte fails to pass verification, up to 10 successive 100 µs pulses are

applied with a verification after each pulse. If the byte fails to verify after 10 pulses have been

applied, the part is considered failed. After the byte verifies properly, the next address is

selected until all have been checked. V_PPis then lowered to 5.0V and V_CCto 5.0V. All bytes

are read again and compared with the original data to determine if the device passes or fails.
