Description

The AT27C512R-70JU is one member of the AT27C512R series.The AT27C512R is a low-power, high-performance 524,288-bit one-time programmable read-only memory (OTP EPROM) organized 64K by 8 bits. It requires only one 5V power supply in normal read mode operation. Any byte can be accessed in less than 45 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems.

Features of the AT27C512R-70JU are:(1)rapid programming algorithm100 s/byte (typical); (2)CMOS and TTL compatible inputs and outputs; (3)integrated product identification code; (4)industrial and automotive temperature ranges; (5)green (Pb/halide-free) packaging option; (6)fast read access time--45 ns; (7)5V±10% supply; (8)high-reliability CMOS technology.The AT27C512R is available in a choice of industry-standard JEDEC-approved one-time programmable (OTP) plastic PDIP, PLCC, SOIC, and TSOP packages. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention. With 64K byte storage capability, the AT27C512R allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media.

The absolute maximum ratings of the AT27C512R-70JU can be summarized as:(1)voltage on any pin with respect to ground:-2.0V to + 7.0V;(2)voltage on A9 withrespect to ground:-2.0V to + 14.0V;(3)Vpp supply voltage with respect to ground:-2.0V to 14.0V;(4)temperature under bias:-55 to 125;(5)storage temperature:-65 to 150.Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied.Exposure to absolute maximum rating conditions for extended periods may affect device reliability.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 0.1 F high frequency, low inherent inductance, ceramic capacitor should be utilized for each device.
