Description
AT27C080 chip low-power, high-performance 8,388,608-bit ultraviolet erasable programmable read only memory (EPROM) organized bits. AT27C080 requires only power supply normal read mode operation. byte accessed less than eliminating need speed reducing WAIT states high-performance microprocessor systems. Atmel's scaled CMOS technology provides active power consumption fast programming. Power consumption typically active mode less than standby mode. (continued)

AT27C080 available choice packages, including; one-time programmable (OTP) plastic PLCC,PDIP, SOIC (SOP), TSOP, well windowed ceramic Cerdip. devices feature two-line control (CE, give designers flexibility prevent contention. With dens byte torage capabi lity, AT27C080 allows firmware stored reliably accessed system without delays mass storage media. Atmel's 27C080 additional features ensure high quality efficient production use. RapidProgramming Algorithm reduces time required program part guarantees reliable programming. Programming time typically only µs/byte. Integrated Product Identification Code electronically identifies device manufacturer. This feature used industry standard programming equipment select proper programming algorithms voltages.
System Considerations
Switching between active standby conditions Chip Enable produce transient voltage excursions. Unless accommodated system design, these transients exceed data sheet limits, resulting device non-conformance. minimum, high frequency, inherent inductance, ceramic capacitor should utilized each device. This capacitor should connected between Ground terminals device, close device possible. Additionally, stabilize supply voltage level printed circuit boards with large EPROM arrays, bulk electrolytic capacitor should utilized, again connected between Ground terminals. This capacitor should positioned close possible point where power supply connected array.
Erasure Characteristics
entire memory array AT27C080 erased (all outputs read VOH) after exposure ultraviolet light wavelength Complete erasure assured after minimum minutes exposure using 12,000 µW/cm2 intensity lamps spaced inch away from chip. Minimum erase time lamps other intensity ratings calculated from minimum integrated erasure dose W.sec/cm2. prevent unintentional erasure, opaque label recommended cover clear window erasable EPROM that will subjected continuous flourescent indoor lighting sunlight.

pulse width used program. address first location. raised 6.5V OE/VPP raised 13.0V. Each address first programmed with pulse without verification. Then verification reprogramming loop executed each address. event byte fails pass verification, successive pulses applied with verification after each pulse. byte fails verify after pulses have been applied, part considered failed. After byte verifies properly, next address selected until have been checked. OE/VPP then lowered 5.0V. bytes read again compared with original data determine device passes fails.
