read mode, AT27C1024 typically consumes Standby mode supply current typically less than AT27C1024 available industry standard JEDECapproved one-time programmable (OTP) plastic PDIP, PLCC, TSOP packages. device features two-line control (CE, eliminate contention high-speed systems. With high density word storage capability, AT27C1024 allows firmware stored reliably accessed system without delays mass storage media. Atmel's 27C1024 have additional features ensure high quality efficient production use. RapidProgramming 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 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.
