1. Description
The Atmel® AT27C080 is a low-power, high-performance 8,388,608-bit, one-time programmable, read-only memory (OTP EPROM) organized as 1M by 8 bits. The AT27C080
requires only one 5V power supply in normal read mode operation. Any byte can be
accessed in less than 90ns, eliminating the need for speed reducing WAIT states on highperformance microprocessor systems.

Read-only Memory
Atmel AT27C080
The Atmel scaled CMOS technology provides low active power consumption and fast programming. Power consumption is typically 10mA in active mode and less than 10µA in
standby mode.
The AT27C080 is available in a choice of industry standard, JEDEC-approved, one-time programmable (OTP) PLCC and PDIP packages. All devices feature two-line control (CE, OE)
to give designers the flexibility to prevent bus contention.
With high-density, 8Mb storage capability, the AT27C080 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media.
The AT27C080 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 50µs/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.

3. System 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 nonconformance.
At a minimum, a 0.1µF, 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 4.7µF 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.

6. Rapid programming algorithm
A 50µs CE pulse width is used to program. The address is set to the first location. VCC is raised to 6.5V and OE/VPP is raised
to 13.0V. Each address is first programmed with one 50µs
loop is executed for each address. In the event a byte fails to pass verification, up to 10 successive 50µs 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. OE/VPP is then lowered to VIL and
VCC to 5.0V. All bytes are read again and compared with the original data to determine if the device passes or fails.
