FINAL Am27C64 64 Kilobit (8 K x 8-Bit) CMOS EPROM DISTINCTIVE CHARACTERISTICS s Fast access time s Latch-up protected to 100 mA from –1 V to VCC + 1 V — Speed options as fast as 45 ns s High noise immunity s Low power consumption s Versatile features for simple interfacing — 20 µA typical CMOS standby current s JEDEC-approved pinout — Both CMOS and TTL input/output compatibility s Single +5 V power supply — Two line control functions s Standard 28-pin DIP, PDIP, and 32-pin PLCC packages s ±10% power supply tolerance standard s 100% Flashrite™ programming — Typical programming time of 1 second GENERAL DESCRIPTION The Am27C64 is a 64-Kbit, ultraviolet erasable programmable read-only memory. It is organized as 8K words by 8 bits per word, operates from a single +5 V supply, has a static standby mode, and features fast single address location programming. Products are available in windowed ceramic DIP packages, as well as plastic one time programmable (OTP) PDIP and PLCC packages. Data can be typically accessed in less than 45 ns, allowing high-performance microprocessors to operate without any WAIT states. The device offers separate Output Enable (OE#) and Chip Enable (CE#) controls, thus eliminating bus contention in a multiple bus microprocessor system. AMD’s CMOS process technology provides high speed, low power, and high noise immunity. Typical power consumption is only 80 mW in active mode, and 100 µW in standby mode. All signals are TTL levels, including programming signals. Bit locations may be programmed singly, in blocks, or at random. The device supports AMD’s Flashrite programming algorithm (100 µs pulses), resulting in a typical programming time of 1 second.
