It requires a single 5V power supply in normal read mode operation. Any word can be accessed in less than 100 ns, eliminating the need for speed-reducing WAIT states. The x16 organization makes this part ideal for highperformance 16- and 32-bit microprocessor systems. The AT27C800 can be organized as either word-wide or byte-wide. The organization is selected via the BYTE/VPP pin. When BYTE/VPP is asserted high VIH , the word-wide organization is selected and the O15/A-1 pin is used for O15 data output. When BYTE/VPP is asserted low VIL , the byte-wide organization is selected and the O15/A-1 pin is used for the address pin A-1. When the AT27C800 is logically regarded as x16 word-wide , but read in the bytewide mode, then with A-1 = VIL the lower eight bits of the 16-bit word are selected with A-1 = VIH the upper eight bits of the 16-bit word are selected. In read mode, the AT27C800 typically consumes 15 mA. Standby mode supply current is typically less than 10 µA. The AT27C800 is available in industry-standard, JEDECapproved, one-time programmable OTP PLCC, PDIP, SOIC SOP and TSOP, as well as UV-erasable windowed Cerdip packages. The device features two-line control CE,OE to eliminate bus contention in high-speed systems. With high-density 512K-word or 1024K-bit storage capability, the AT27C800 allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. Atmel’s AT27C800 has additional features that 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 50 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 equipment 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 datasheet 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.
