Description
AT27C2048 low-power, high-performance 2,097,152-bit one-time programmable read-only memory (OTP EPROM) organized 128K bits. requires single power supply normal read mode operation. word accessed less than eliminating need speed-reducing WAIT states. by-16 organization makes this part ideal high-performance microprocessor systems. read mode, AT27C2048 typically consumes Standby mode supply current typically less than AT27C2048 available industry-standard JEDEC-approved one-time programmable (OTP) plastic PDIP, PLCC, VSOP packages. device features two-line control (CE, eliminate contention high-speed systems. With high density 128K word storage capability, AT27C2048 allows firmware stored reliably accessed system without delays mass storage media. Atmel's AT27C2048 additional features that ensure high quality efficient production use. Rapid Programming Algorithm reduces time required program part guarantees reliable programming. Programming time typically only µs/word. 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 datasheet 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.

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