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

Atmel’s scaled CMOS technology provides low active power consumption, and fast programming. 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 programmable (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 guarantees 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 algorithms and voltages.
Switching
Considerations
Switching between active and standby conditions via the Chip Enable pin may produce transient 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 VCC and 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 VCC and Ground terminals. This capacitor should be positioned as
close as possible to the point where the power supply is connected to the array.

A 100 µs CE pulse width is used to program. The address is set to the first location. VCC is
raised to 6.5V and VPP is 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. VPP is then lowered to 5.0V and VCC to 5.0V. All bytes
are read again and compared with the original data to determine if the device passes or fails.
