1. Description

The AT27C080 chip 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 90 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 10 mA in active mode and less than 10 µA in standby mode.
The AT27C080 is available in a choice of packages, including; one-time programma­ble (OTP) plastic PLCC, PDIP and TSOP. All devices feature two-line control (CE OE
) to give designers the flexibility to prevent bus contention.
With high density 1-Mbyte storage capability, the AT27C080 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media.
Atmel’s AT27C080 has additional features to ensure high quality and efficient produc­tion use. The Rapid part and guarantees reliable programming. Programming time is typically only 50 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.
Programming Algorithm reduces the time required to program the

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

18. Rapid Programming Algorithm

A 50 µs CE pulse width is used to program. The address is set to the first location. VCC is raised to 6.5V and OE 50 µs CE each address. In the event a byte fails to pass verification, up to 10 successive 50 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. OE are read again and compared with the original data to determine if the device passes or fails.
