nization make this part ideal for high-performance 16- and 32-bit microprocessor systems.

In read mode, the AT27C1024 typically consumes 15 mA. Standby mode supply current is typically less than 10 µA.

The AT27C1024 is available in industry standard JEDECapproved one-time programmable OTP plastic PDIP, PLCC, and VSOP packages. The device features two-line control CE, OE to eliminate bus contention in high-speed systems.

With high density 64K word storage capability, the AT27C1024 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media.

Atmel’s 27C1024 have 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 100 µs/word. 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.

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 data sheet limits, resulting in device non-conformance. At a minimum, a µF 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 µF 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.
